Sounds Coming from the Vehicle and Their Meanings

 

                                           Sounds coming from a vehicle can indicate certain malfunctions. If sounds from the car are ignored, problems that could be solved quickly can escalate. These sounds can be caused by various reasons. They can range from noises from the exhaust and front suspension to engine or braking system malfunctions. Based on these sounds, it's appropriate to discuss common issues seen in most cars.

                                                        Noises coming from the engine   

                          • Clicking Sound: This is a sound coming from the top of the engine block. It originates from the valves and pistons. If the oil level is low, a clicking sound will come from the engine. Insufficient oil level prevents the valves from being adequately lubricated. Checking the engine oil level and taking precautions beforehand will prevent the problem.

                           • Humming Sound: The humming sound coming from the engine is primarily caused by the lower section. It's a humming sound that increases with wear on the belt. The V-belt can wear down and loosen over time. When it loosens, the humming sound gradually increases. Malfunctions in the alternator, water pump, or air conditioning components can also cause a humming sound.

                                                        Sounds Coming from the Brakes     

                             • Squeaking Sound: This is the most common sound heard when braking. The main cause of the sound is the brake pads. Wear on the brake pads prevents them from making full contact with the disc when the brakes are applied. If contact with the disc is lost, squeaking sounds will occur.

                            • Grinding or Friction Sound: If you hear a sound like metal rubbing against something when you press the brake, this is a serious problem. It indicates that the brake pads are completely worn out. If not resolved quickly, there will be a sudden drop in braking performance.

                                                  Noises Coming from the Steering System

                           • Clicking or Knocking Sound: Clicking noises coming from the steering wheel are related to the steering box or tie rods. If a clicking sound is heard when the steering wheel is turned, it means that wear has begun in the box section. This fault should be suspected if the steering response is slow.

                         • Humming or Buzzing Sound: If you hear a buzzing or excessive humming sound from the wheel while turning the steering wheel, it indicates wear on the connection between the steering wheel and the wheel. Addressing the problem before it worsens can prevent major malfunctions.

                                                    Noises coming from the transmission 

                Noises originating from the transmission are usually due to a decrease in transmission oil. A decrease in oil level or the use of poor quality oil can increase the noise coming from the transmission. The noise is most noticeable during gear changes. Thorough inspection of transmission components and resolution of wear problems will improve the situation.

                                                         Sounds coming from the exhaust

                  A rattling sound from the exhaust indicates a problem caused by a puncture or wear on the exhaust surface. It's normal for the exhaust to develop punctures over time due to excessive heat. If the sound is very loud when accelerating, it indicates gas leaks. A decaying exhaust system causes these leaks, and the sound intensifies with each acceleration.

                                                            Suspension Noises

                    Squeaking noises coming from the suspension indicate that the shock absorber part is broken or severely worn. If the squeaking noise increases on bumpy roads, checking the shock absorber bushings will solve the problem.

Self-Charging Electric Car Models

 

                            Electric vehicle models have approached modern technology with the initiative of major brands. Vehicles that derive their motor power from electricity have become remarkable with their long-range capability. Recently, the most talked-about are self-charging electric vehicles. By generating their own electrical current, the problem of connecting to an external power source is eliminated. Self-charging vehicles are hybrid models. Hybrid models are systems based on the simultaneous operation of the motor and electricity. Hybrid technology does not rely on external power. It renews energy when braking or when the vehicle is stopped. It extends the battery life in a short time. Simultaneously, gasoline use is activated, converting the energy it receives from there into charging. Some prominent brands are switching to hybrid systems in their electric vehicle models, completely eliminating the need to stop and recharge on the road.

                                                  Self-Charging Electric Vehicles  

                         1. Toyota Corolla Hybrid: This model, developed by Toyota using entirely hybrid technology, features a self-charging system. It generates energy independently by recharging itself during frequent stop-and-go city driving, eliminating external dependence. With a full charge, it has a range of 1000-1200 km.

                        2. Honda CR-V e:HEV: This Honda model, capable of fully self-charging, draws its power from hybrid operation for short distances. It recharges itself when braking in traffic or while waiting at red lights. There's no need to recharge the battery in city driving. With a full tank, it can travel 800-1000 km on a long range.

                      3. Hyundai Tucson Hybrid: This model has two different power outputs. With its self-charging hybrid system, it can travel 80 km in the city. There is no need for external charging. The range will increase slightly when the battery is fully charged. Charging is not necessary in the city; you can continue driving using its self-charging feature.

                     4. Kia Sportage Hybrid: The Sportage model, produced by the KIA brand with hybrid technology, has become independent of external power sources by charging itself. Thanks to its self-renewing technology, it can travel 70-80 km in city driving. Its range increases with a fully charged battery.

                     5. Lexus NX Hybrid: Lexus, experimenting with hybrid technology, achieved a range of 96 km in urban areas. This electric vehicle, notable for its self-recharging technology, allows for comfortable long-distance travel on a full tank.

                     6. Renault Austral E-Tech: Renault's shift towards electric vehicles has greatly contributed to its self-charging system. Its latest model can activate its own charging capacity in city driving, covering 80% of the range. When the hybrid battery mode is activated, it has a range of up to 1200 km.

                     7. Nissan X-Trail e-Power: Nissan has implemented its own brand of electric vehicle technology and developed a self-charging vehicle. It has demonstrated advancement by generating its own electricity in urban areas and achieving long-distance travel. With its dual-motor technology, its range can exceed 1000 km.

                                             How does the self-charging feature work?

             Hybrid technology helps the vehicle convert its own electrical current into power. Electric vehicle models can operate with the power of two motors. Self-charging electric vehicles derive their operating principle from hybrid power. When braking in the city, the motor generator current is activated. The generator converts the electricity it receives from the motor into a charge. The charge is replenished with stop-start driving. It is entirely based on the principle of converting energy from the motor into electricity and charging.

Car Engine RPM Increase Problem and Solution

 

                           A vehicle engine provides performance by operating at a specific RPM level. Sudden increases in RPM, or the engine's inability to regulate itself, can cause malfunctions. When an RPM surge malfunction occurs, the vehicle may exhibit erratic behavior. Problems can progress to spontaneous acceleration, rapid starting, or noisy engine operation. Sudden RPM surges lead to increased fuel consumption. Wear and tear on engine parts can occur, and serious problems may arise over time. The spontaneous increase and decrease in RPM, and its continuation while driving, causes the vehicle to consume more energy than normal. If an RPM surge malfunction occurs, prompt inspection and repair are recommended.

                                                 Reasons for Increased Car Engine RPM

                 1. Dirty or Faulty Throttle Body: The throttle body is responsible for regulating engine speed. If the throttle body becomes dirty, it cannot deliver enough airflow to the engine compartment. This dirt can lead to throttle body malfunction. It is the first part to be checked.

                2. Vacuum Leaks: If vacuum leaks occur along with the part called the intake manifold, the engine will draw in unnecessary air. This airflow, outside of its normal settings, will cause sudden increases and decreases in engine speed. Parts that can cause vacuum leaks should be regularly maintained. 

               3. Sensor Errors: Fluctuations in engine speed can be caused by malfunctions in the engine coolant temperature sensor, temperature sensor, airflow regulator parts, and the accelerator pedal. These parts directly regulate the engine's own settings.

               4. LPG Adjustment Problem: Improper adjustment of the LPG system in vehicles, or failure to check the LPG settings for an extended period, can trigger engine speed problems. If there are gas leaks in the vehicle, the engine speed cannot be adjusted to its full capacity.

            5. Electrical System Problems: If the battery voltage is low or there is wear and tear on the battery, it cannot transmit electrical current properly. A system that does not receive a proper electrical voltage will experience deviations in speed regulation.

         6. Clutch Disc Slippage: If the engine speed increases while moving when the gas pedal is pressed but the vehicle doesn't accelerate, the clutch disc is worn out. The necessary parts should be replaced as soon as possible.

                                           Solution to the Engine Speed ​​Increase Problem

               • Diagnostic tool to identify the problem. 

              • Throttle body cleaning or replacement. 

             • Checking vacuum hoses and related parts. 

            • Maintenance and repair of necessary sensor components.

Car Ignition Failure Symptoms and Repair

 

                                 Ignition failures in vehicles can lead to increasingly serious problems. When the ignition system malfunctions, the vehicle experiences unforeseen problems. The ignition system, which enables the vehicle to start, prevents the vehicle from running if it doesn't receive the necessary electricity. Without ignition, the engine cannot reach full capacity. Ignition engages during the initial start-up. If the ignition doesn't fully reach the spark plugs when the ignition is turned, the engine speed decreases. The car experiences shaking and difficulty starting the engine. It can also lead to sudden stalling. Early detection and repair of ignition system failures will prevent major damage.

                                                  Ignition System Malfunction Symptoms

                        Difficulty Starting the Engine: If the car is difficult to start in the morning or in cold weather, or if it stalls after starting, it indicates an ignition problem. If the engine vibrates excessively and makes a loud noise when the car starts, the problem may be related to the ignition.

                        Engine Misfiring and Shaking: If the vehicle fails to reach a stable RPM after starting and shakes excessively, it means the ignition system is not transmitting electrical power properly. If misfiring occurs while the vehicle is in motion, it indicates a problem with the ignition system and the spark plugs.

                        Power Loss and Acceleration Problem: If the acceleration time drops below normal when the accelerator is pressed, there is a power loss due to the ignition. A decrease in speed again during acceleration is a problem stemming from the same fault.

                         Increased Fuel Consumption: Power loss and strain on the vehicle are factors that increase fuel consumption. Hard operation and inefficient running while the vehicle is in motion lead to rapid fuel depletion.

                       Gasoline Smell from Exhaust: When the ignition doesn't burn sufficiently, the gasoline can't reach the required temperature. This causes a smell or smoke to come from the exhaust.

                                               Ignition System Malfunction Repair     

                   1. Repairing Spark Plugs and Spark Plug Wires: The chrome plating on spark plugs can wear down, preventing them from transmitting power properly to the engine. If the spark plug wires are broken or malfunctioning, they must be replaced as a set. Repairing or restoring them is not possible.

                  2. Ignition Coil: A malfunction in the coil means that insufficient electricity is reaching the cylinder. Ignition coils cannot be repaired. Replacing the coil with a new one after a malfunction will solve the problem.

                 3. Distributor Replacement: Distributor failures are common in older model vehicles. The surface of the part can easily absorb moisture, preventing the clutch from reaching the spark plugs. The part cannot be repaired; replacement with a new one is recommended when it fails.

              4. Ignition Sensor Repair: If the sensor inside the ignition module malfunctions, it can cause the vehicle to stall along with the crankshaft. Identifying and directly replacing the faulty part in the ignition system is the definitive solution to the problem.

How to Choose the Right Oil for Your Vehicle Model

 

                         There are several factors to consider when choosing the right oil for your vehicle model. Selecting the correct oil involves careful calculations, from the car's make to its fuel consumption. Since each brand has its own unique engine operating system, using the wrong engine oil can lead to serious malfunctions. Engine oil selection should be done at professional service centers. For new vehicles, it's wise to entrust the process to experts to ensure optimal performance.

                                                        How should oil be chosen?

                 Fluidity: Oil containers have numbers on the front. Each number represents the appropriate fluidity for the engine of the vehicle make. Using oil that does not provide sufficient performance in terms of fluidity will gradually shorten the engine life.

                 Oil Type: In newer generation vehicles, the oil type is generally synthetic. A synthetic oil type suitable for seasonal conditions is required. Oil types that are not compatible with the vehicle engine and do not transmit fluidity properly will cause damage.

                 Driving Conditions: For continuous city driving, very high-quality oils should be selected. Those who drive long distances should use oils that can withstand high temperatures. If the vehicle is used in dusty environments or harsh weather conditions, frequent oil changes should be performed.

                Fuel Type: Selectivity is key in diesel vehicles. Additive changes are different in diesel engines. Oils that sense the vehicle's operating system are the first choice. In other engine types, quality-enhancing options will be accepted.

                                         Malfunctions Caused by Incorrect Oil Selection

               Using the wrong engine oil can cause malfunctions in the parts that enable the vehicle to operate. The engine will overheat, leading to wear and tear on other parts. Engine components that cannot withstand the heat will quickly fail. Using incompatible oil can cause leaks and, combined with high temperatures, can even lead to a fire in the car. Choosing oil quality that matches the vehicle's engine and the car's brand is paramount to avoid causing further damage.

What to do if the brakes fail while the vehicle is in motion?

 

                         This is the most serious malfunction that can occur in cars. This type of malfunction, which can reach a very dangerous level, brings with it major problems. If the brakes fail while the vehicle is in motion and the car accelerates, it causes great panic for the driver. It's a malfunction caused by brake failure. If the brakes fail, they lose all function. No matter how hard you press the brake pedal, it won't work. Staying calm will prevent a potentially bad scenario.

                                                       What to do if the brakes fail   

                           1. Taking Your Foot Off the Gas: If braking has no effect while the vehicle is traveling at a normal speed, you need to take your foot off the gas. Panicking and holding down the gas pedal will only cause the vehicle to continue increasing its speed.

                          2. Pumping the Brake Pedal: Repeatedly pressing and releasing the brake pedal helps to disperse any air pockets that may have formed. Pressing and holding the brake pedal down quickly won't help. Pumping the brake pedal by pressing and releasing it repeatedly can be beneficial.

                         3. Downshifting Method: In manual cars, it is necessary to reduce speed by downshifting. The vehicle is slowed down by downshifting in a controlled manner. The handbrake is applied and released depending on the decrease in speed. In automatic cars, the gear should be put into "S and L" mode.

                         4. Using the Handbrake Carefully: Pulling the handbrake too quickly will cause the vehicle to swerve. This poses a significant risk of accident. It is advisable to pull and release it slowly and carefully. When downshifting, the handbrake should be used according to the vehicle's deceleration rate.

                      5. Warning the Surroundings by Turning On the Hazard Lights: If the brakes fail and the vehicle is in a crowded area, it's necessary to immediately turn on the car's hazard lights to warn those around you. Hand gestures can also be used to signal a warning to oncoming vehicles or those in front.

                      6. Steering the Vehicle to a Safe Location: Calmly driving the car to the side of the road, into an empty field, or onto an escape ramp will be advantageous. Turning the vehicle towards a steep, inclined area like a ramp will greatly help in reducing speed.

                                                  Things to Avoid Doing in a Panic

                   • Not taking your foot off the gas pedal. 

                  • Pulling and releasing the handbrake suddenly. 

                 • Driving into a crowded area instead of a quiet road. 

                • Trying to stop the vehicle by turning off the ignition.

Reasons for Smoke Coming from the Hood While the Vehicle is in Motion

 

                                  This is a type of malfunction that can occur in vehicles. Smoke rising from the front of the vehicle while it is in motion is a risky situation. It requires calm handling. While smoke from the hood may be normal in some cases, it can sometimes indicate a very serious malfunction. If smoke starts rising from the hood and its intensity increases, it is recommended to stop the vehicle immediately and take precautions. The causes of smoke vary. A malfunction starting in the engine can change as other parts become involved due to overheating. If the cause of the smoke from the hood is correctly identified, repairs can be carried out quickly. Solving the source of the malfunction that triggers the smoke is the primary goal.

                                                Reasons for Smoke Coming Out of the Hood

                     Overheating: The vehicle overheats due to an increase in engine temperature. This can be caused by overheating due to a malfunction in the engine cooling system, resulting in cracks in the pipes. Smoke can also result from a combination of radiator leaks and engine heat.

                     Oil Leak: Oil leaks, such as seepage of engine oil or similar spills, can cause smoke to be produced when combined with heat.

                     Cylinder Head Gasket Failure: Excessive heat is generated after coolant leaks into the combustion chamber. This causes the smoke to rise and increase.

                     Electrical System Malfunction: A cable malfunction in the electrical box produces a small amount of smoke along with high heat. If the electrical system malfunction is significant, the intensity of the smoke gradually increases.

                                                     What to do if smoke starts coming from the hood?

                        1. Stop the Vehicle Safely: After smoke starts coming out, the vehicle needs to be stopped safely. Bring the vehicle to a safe location. Allow the engine to cool down

                         2. Don't Open the Hood Immediately: The hood shouldn't be opened immediately. Because the engine temperature is very high, opening the hood can cause excessive smoke to fill the vehicle. This creates an environment for the release of more heat than necessary.

                         3. Check: Once the engine temperature returns to normal, check the oil level and coolant. This will identify any leaks or pipe cracks.

                      4. Call for Help: If the problem persists after the checks, starting the vehicle will likely lead to a major breakdown. It's wise to call for help if the problem continues.
