Reasons for abnormal combustion causing engine shaking, the common causes of abnormal combustion are usually: 1. Abnormal ignition, such as spark plug damage, ignition module failure, etc. 2. Intake and exhaust problems, mainly caused by valve erosion. 3. Engine misfire, this reason is more complex, from the ignition system, to the air-fuel ratio, even the self-learning function of the ECU, can lead to misfire. Reasons for vehicle body shaking during idle: 1. Severe engine carbon buildup. 2. Ignition system problems. 3. Unstable oil pressure. 4. Aging of engine components.

Will smoke come out of the intake pipe if smoke is blown into the oil filler port?

Will smoke come out of the intake pipe if smoke is blown into the oil filler port. Smoke from the intake pipe: When the engine is running, the oil splashes inside the machine. Combined with the influence of temperature, the oil atomizes and produces smoke. This is a normal phenomenon and there is no need to worry. Crankcase exhaust gases: Crankcase exhaust gases are the result of oil frying the piston. This phenomenon is common. There is a thin pipe on the cylinder head that sucks the exhaust gases back into the engine for re-combustion before emission, to avoid environmental pollution. This is called crankcase exhaust gas recirculation. Some posts mention installing an oil catch can to filter these exhaust gases, which is a normal phenomenon. Shape of the engine intake port: The position of the intake port varies among different car models. Some car models have the intake port at the front of the engine, while others have it at the rear. The location and shape may differ from car to car. The air filter is installed between the intake port and the throttle port, shaped like a rectangular plastic box.

Are German Cars Noisier Than Japanese Cars in Terms of Engine Noise?

The reasons for loud engine noise in cars are as follows: Weather Conditions: Cold weather can cause the engine idle speed to increase. When the engine remains at high RPM while cold, it may feel like the engine noise is louder, which is a normal phenomenon. Loose Plastic Components in the Engine Compartment: For example, the engine cover or intake pipe may be loose and need tightening. Noises from engine belts, including power steering belts and alternator belts, can occur if they are aged, too loose, or too tight. Replace or adjust the tension as needed. Incorrect Engine Oil Condition: Engine oil is crucial for lubrication. Issues with the oil can affect engine performance. If the oil viscosity is too high, it can cause operational problems, reduce lubrication efficiency, and lead to increased friction and noise during engine operation.

Does Traffic Jam Consume Fuel?

Being stuck in traffic for ten minutes with the engine running consumes a certain amount of fuel. However, you can avoid wasting fuel by turning off the engine during those ten minutes of traffic congestion. Definition of Fuel Consumption: Fuel consumption refers to the amount of fuel used corresponding to the distance traveled by a vehicle. Constant-speed fuel consumption is an indicator of fuel efficiency when a car is driven at a constant speed on good road conditions. The commonly mentioned "liters per 100 kilometers" refers to how many liters of fuel a vehicle consumes for every 100 kilometers traveled, where "liters" is equivalent to "L" (liters). Factors Affecting Fuel Consumption: Vehicle fuel consumption is influenced by many factors, including driving conditions and driving habits. Examples include prolonged engine idling, sudden braking, inconsistent driving speeds, insufficient tire pressure, aggressive acceleration, and long-distance driving at high speeds in low gears. Additionally, road conditions significantly impact fuel consumption, especially in urban traffic situations where traffic jams are common.

What Causes Engine Shaking After Cylinder Head Assembly Replacement?

The causes of car accelerator pedal shaking include engine misfire, dirty engine throttle, and aging rubber components inside the mounts. Below are the specific reasons for car accelerator pedal shaking: Engine Misfire: This may be due to an engine misfire fault, causing one or more cylinders to stop working, resulting in severe engine shaking transmitted to the accelerator pedal. Common fault points for misfires include: faulty spark plugs, malfunctioning ignition modules, or poor fuel quality. Dirty Engine Throttle: It could be caused by a dirty engine throttle, leading to engine shaking. It is recommended to inspect the throttle and clean it if excessively dirty. Aging Rubber Components Inside Mounts: The shaking may be due to aging rubber components inside the engine and transmission mounts, which can no longer absorb the vibrations generated during engine operation, causing the shaking to be transmitted to the accelerator pedal.

Do I need to go to the local DMV to sell a car?

Selling a car and transferring ownership must be processed at the DMV in the city where the vehicle's license plate is registered. Documents required for selling a car: Vehicle Registration Certificate: The vehicle must be within the valid inspection period, and the registration certificate must have proof of the valid inspection. Vehicle Title (Registration Certificate): If the vehicle title is missing, it must be reissued before the transfer can proceed. Proof of Vehicle Purchase Tax: Generally, legally traded vehicles have this document, but special cases like "black plate" vehicles, smuggled cars, or confiscated vehicles lack this proof. The purchase tax must be paid, and the proof must be issued before the transfer. Invoice for the Vehicle: The original purchase invoice or the last transfer receipt is required. If the seller loses it, an individual can write and sign a statement, while a company must affix its financial seal on the statement. Identity Proof: The original ID of the vehicle owner is needed. For company-owned vehicles, the company seal and organization code certificate are required. If the company has changed its name or gone out of business, a proof from the industrial and commercial department is necessary.

What Size of Car Cleaning Cloth is Suitable?

Fogging on the windshield when using the heater is mainly caused by the temperature difference between the inside and outside of the car. Due to the warm interior and cold exterior, water vapor condenses on the cold glass, forming fog in a short time. Wiping with a cloth: This method is simple and easy, but the effect is short-lived, as the glass quickly becomes foggy again. Additionally, wiping the windshield while driving is not very practical, as it can seriously interfere with normal driving and may even pose a danger. Using hot air to defog: However, this method should not be used while driving. It is best to stop the car and use the heater to blow hot air directly onto the glass. Initially, the fog may increase, but after a few minutes, the moisture inside the car will dry out, preventing recurring fogging. Homemade defogging solution: You can easily make your own 'anti-fog solution' by mixing dish soap and water in a ratio of 1:10. Then, use a clean, soft cloth to dip into the solution and apply it to the inside of the front and rear windshields. This method is both simple and cost-effective.
