How many kilometers can domestic cars run at most
1 Answers
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.
