What Causes Incomplete Engine Combustion?

Engine incomplete combustion is caused by damaged spark plugs, poor fuel quality, and excessive carbon deposits. Damaged Spark Plugs: The most common issue is damaged spark plugs. Worn spark plug electrode gaps result in insufficient ignition, leading to unburned air-fuel mixture and engine vibration during acceleration. Poor Fuel Quality: Low-quality gasoline leads to poor fuel injector atomization, causing incomplete combustion in the cylinder. It's recommended to switch to higher-octane gasoline after using up the current tank and perform a fuel system cleaning. Excessive Carbon Deposits: A dirty throttle body or carbon-clogged fuel injectors can cause throttle valve leakage or idle speed control motor jamming, resulting in high idle speed. Carbon buildup during engine operation also contributes to incomplete combustion.

How many years is the validity period of the driving test?

The validity period of the driving test is 3 years. Here is some information about the validity period of the driving test: 1. Validity period: The study driving certificate becomes invalid 3 years after issuance. If you fail to complete all subjects within 3 years, all passed subject scores will be invalidated. If you still need to obtain a driver's license, you will need to re-register and retake all subjects. 2. Specific regulations: Applicants who study driving on the training ground and roads must obtain a study driving certificate as required. The study driving certificate is valid for three years, and applicants must complete the subject two and subject three tests within the validity period.

How High is a Car's Chassis Generally?

Car chassis should be no less than 140mm. Ground clearance: Ground clearance is a very important parameter when choosing a car. Most European passenger cars have a ground clearance between 100 and 140mm, while most Japanese and Korean passenger cars range from 140 to 180mm. Generally, off-road vehicles have a ground clearance between 180 and 220mm. Purpose of car chassis height: The higher the chassis, the better the vehicle's passability, but the stability is relatively poor. If you want to maintain stability while increasing the vehicle height, the tires need to have greater grip, which comes at the cost of higher fuel consumption. This is also why off-road vehicles consume so much fuel. A lower chassis brings comfort and lower fuel consumption, but when encountering ditches or bumps, the passability is not as good.

What Causes a Car Key to Get Stuck?

Car keys get stuck due to incorrect parking gear position and steering wheel lock. Here are some explanations about why car keys get stuck: 1. Incorrect parking gear position: This may occur when an automatic transmission's P (Park) gear isn't fully engaged. Sometimes it appears to be in position but hasn't triggered the electronic sensor, or there might be obstacles like coins in the gear slot preventing proper engagement. 2. Steering wheel lock: The inability to turn the key after insertion might result from the steering wheel not being properly aligned during the last parking, causing abnormal locking. To resolve this, try gently turning the key with your right hand while simultaneously wiggling the steering wheel left and right with your left hand - this should allow the key to turn.

What is the Problem of Abnormal Noise in the Vehicle Rear Axle?

Abnormal noise in the vehicle rear axle is caused by improper clearance in the differential housing. Below are some explanations regarding the abnormal noise in the vehicle rear axle: 1. Improper side gear clearance: Incorrect fit between the differential cross shaft journal and the differential housing, improper side clearance between the axle spline gear and the differential side gear keyway, and improper meshing clearance between the differential side gear and the planetary gear. 2. Cause analysis: Insufficient gear oil or decreased viscosity, improper adjustment of the support bearing tightness, improper adjustment of the main reducer gear engagement clearance, and excessive gear wear or damage are all reasons for abnormal noise in the vehicle rear axle.
