It mainly depends on the usage of the vehicle and the quality of the car. Domestic cars generally require major repairs after running about 100,000 kilometers, while imported cars can run more than 100,000 kilometers. Within the first 3,000 kilometers, the maximum engine speed should be 70% of the rated speed, and the maximum speed should not exceed 80 kilometers per hour. After a car has been driven for a certain number of years or kilometers, due to severe wear and aging of internal engine components, the power performance significantly declines. At this point, it is necessary to replace engine components such as valves, pistons, cylinder liners, perform cylinder boring, and crankshaft grinding. After a major overhaul, the engine performance can be restored to more than 90% of its original state.

What's the Difference Between D and S Gears in an Automatic Transmission Car?

D stands for "Drive", representing the forward gear, while S stands for "Sports", representing the sport mode. The specific descriptions are as follows: 1. D gear covers all the forward gears in the car's automatic transmission. When the car is in D gear, the driver does not need to control the gear shift, but directly operates the throttle and brake, which is suitable for daily driving. When driving on mountain roads or climbing slopes, it is recommended to shift to a lower gear. 2. S gear is the sport mode. When the car is in this mode, the transmission can shift gears freely, but there is a delay in shifting. The engine maintains high-speed operation to obtain more power and faster acceleration capability, which is suitable for climbing slopes and quick overtaking.

What is a fuel injector composed of?

A fuel injector is mainly composed of a nozzle and the injector body. The following is an introduction to the working principle and types of fuel injectors: Working principle of a fuel injector: Its main working principle is to atomize the fuel and then distribute it in the combustion chamber to mix with air. The fuel injector has good anti-clogging, anti-contamination, and atomization properties. Classification of fuel injectors: Common types include hole-type fuel injectors and pintle-type fuel injectors. Hole-type fuel injectors are mostly used in direct injection combustion chambers, while pintle-type fuel injectors are mainly used in divided combustion chambers. They can also be classified according to the number of injection ports or holes.

Should You Shift Gears or Engage the Handbrake First When Starting a Car?

When starting a car, first engage the handbrake, then shift to P gear, and press the accelerator to start. For automatic transmission models with an electronic handbrake, after closing the door, fastening the seatbelt, and with the engine idling, pressing the accelerator will automatically release the electronic handbrake. The specific reasons are as follows: 1. The letter 'P' in P gear stands for 'park,' meaning parking gear. When in P gear, a pawl installed on the transmission housing engages with the internal gears of the transmission, locking the entire transmission drive components and the car's entire drive system to prevent situations like the car rolling away if the handbrake is forgotten. 2. The handbrake activates the braking system, locking the wheels to secure the vehicle.

What are China III and China IV Vehicles?

China III and China IV vehicles refer to the automobile exhaust emission standards, corresponding to the policy standard named 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China Phase II, III, IV)'. Below is an introduction to the emission standards: 1. Introduction to Emission Standards: Emission standards regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust. These standards are established to prevent environmental pollution caused by exhaust from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Technical Measures: To stably meet the vehicle emission standards, vehicles must be equipped with technical measures that ensure pollutant emissions comply with the national standards, and they must use fuel that meets the standards.
