Fuel Vehicle

A: It may be caused by insufficient battery power, aging spark plugs or fuel system blockage.

A: It may be caused by fuel system blockage, engine wear, emission system failure or bad driving habits (such as slamming on the accelerator, sudden braking).

A: The lack of power may be caused by engine wear, intake system blockage, fuel system failure or insufficient tire pressure.

A: The brake pads and brake fluid should be checked regularly to ensure that the brake system is working properly. If the braking performance is significantly reduced, it should be promptly inspected and repaired at a professional repair shop.

A: The tire pressure should be checked regularly and adjusted according to the recommendations of the vehicle manufacturer. Normally, the front wheel air pressure is between 240-280kPa, and the rear wheel air pressure is between 220-260kPa (may vary depending on different models).

A: Coolant is used to cool the engine and prevent it from overheating. The coolant level should be checked regularly and added or replaced when necessary.

A: It is recommended to replace the air filter every 10,000 kilometers to prevent impurities from entering the engine.

A: The fuel filter is used to filter impurities in the fuel to prevent it from entering the engine. It is recommended to replace the fuel filter every 30,000 kilometers (or as recommended by the manufacturer).

A: Spark plugs are very important for the normal operation of the engine. It is recommended to replace the spark plugs every 60,000 kilometers for naturally aspirated engines and every 50,000 kilometers for turbocharged engines.

A: Black smoke indicates that the engine mixture is too rich, resulting in incomplete combustion; white smoke may be caused by poor injector atomization, water in the gasoline or water in the cylinder; blue smoke indicates that the engine oil enters the combustion chamber to participate in combustion, which may be caused by piston ring wear, excessive engine oil and other reasons.

A: Yes, the vehicle must be turned off when refueling to ensure safety.

A: When a fuel vehicle is not used for a long time, you should ensure that there is enough fuel in the tank to prevent the tank from rusting, and start the vehicle regularly to keep the engine and battery in normal condition.

A: The three-way catalytic converter is a purification treatment device used to reduce exhaust pollutants discharged by the engine. Carbon deposition will block the filter holes of the three-way catalytic converter, resulting in its performance degradation, increased fuel consumption and exhaust emissions.

A: You should choose an engine oil that meets the vehicle manufacturer's recommended specifications. Usually, the engine oil specifications will be stated in the vehicle manual.

A: Suspension system failure may manifest as unstable vehicle driving, abnormal noise, steering wheel shaking and other problems.

A: Air conditioning system failure may be caused by insufficient refrigerant, air conditioning filter blockage or air conditioning pipe leakage. You should go to a professional repair shop for inspection and repair.

A: Electrical system failure may be caused by insufficient battery power, generator failure, line short circuit or aging of electrical components.

A: Avoiding long-term low-speed driving, regularly cleaning the throttle and engine internal carbon deposits, and using high-quality fuel can help reduce carbon deposits.

A: Regular maintenance includes changing the engine oil and oil filter, air filter and air conditioning filter, checking tire pressure and wear, checking the brake system and coolant level, etc.

A: Fuel vehicles work by using a combustion engine to convert the energy in the fuel into mechanical energy to power the vehicle.
