How Often Should a Car's Timing Belt Be Replaced?

Car timing belts should be replaced approximately every 60,000 to 80,000 kilometers. Other situations that require replacement include: 1. The car lacks power and cannot accelerate when going uphill; 2. The engine shakes severely at idle; 3. The exhaust pipe makes a popping sound when accelerating; 4. There is a knocking sound inside the engine when starting the motor; 5. The timing belt shows cracks or wear. The car timing belt is a critical component of the engine's valve system. As a rubber part, its function is to ensure the accuracy of intake and exhaust timing, synchronize the engine's ignition with cylinder movement, and guarantee smooth power output from the engine.

What does SM in engine oil mean?

SM in engine oil refers to the API oil quality grade. API is the abbreviation for the American Petroleum Institute. The API grade represents the quality grade of engine oil, using simple codes to describe the working capability of engine oil. It is divided into SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, and SN grades, with the later letters indicating higher grades. The main components of engine oil are: 1. Base oil: The main component of lubricating oil, determining the basic properties of the lubricating oil; 2. Additives: They can compensate for and improve the shortcomings of the base oil's performance.

What is the Basic Function of a Car Chassis?

The basic function of a car chassis is to support and mount the car engine and its various components and assemblies, forming the overall shape of the car, receiving the engine's power to enable the car to move and ensure normal driving. The main components of a car chassis are: the transmission system, the running system, the steering system, and the braking system. The maintenance methods for a car chassis include: 1. Avoid driving over large rocks or bumpy areas to prevent damage to chassis components; 2. Install an engine guard or chassis armor; 3. After the chassis comes into contact with rainwater, rinse it thoroughly with plenty of fresh water or a neutral cleaning agent as soon as possible.

What is the Difference Between Electronic Fuel Injection and Direct Injection?

Electronic fuel injection and direct injection mainly differ in the way the engine injects fuel: in an electronic fuel injection engine, the fuel mixes with air in the intake manifold before entering the cylinder for combustion; in a direct injection engine, the fuel is injected directly into the cylinder for combustion. Features of electronic fuel injection include: 1. The gas mixes with gasoline in the intake manifold, resulting in a more uniform mixture; 2. The angle of the fuel injector is precisely aimed at the intake valve, allowing the gasoline to clean carbon deposits on the valve to some extent during injection; 3. High reliability and easy maintenance, as the fuel injector is not inside the cylinder and is unaffected by high temperature and pressure. Features of direct injection include: 1. High precision in fuel injection, eliminating concerns about gasoline adhering to the intake manifold; 2. Direct injection into the cylinder allows for a higher compression ratio, and the atomized gasoline can directly lower the temperature inside the cylinder; 3. Enables stratified combustion.

What Causes Car Jerking?

The reasons for car jerking are: 1. Engine oil passage blockage; 2. Dirty transmission oil clogging the oil passage; 3. Damaged transmission solenoid valve; 4. Forgetting to release the handbrake; 5. Irregular wear of the clutch; 6. Damaged solenoid valve; 7. Some engine cylinders not working; 8. Poor volatility of low-quality fuel. The solutions for car jerking are: 1. Check the transmission temperature and cooling system; 2. Replace the transmission oil; 3. Check if the internal valve body of the transmission is damaged and needs replacement; 4. Check for carbon deposits in the engine valves and intake pipe that need cleaning.
