How Long is the National Standard Warranty for Engine Overhaul?
1 Answers
Our country currently mandates that manufacturers provide a warranty for engines of no less than 40,000 kilometers or two years. Key points for engine maintenance: Use the appropriate grade of engine oil and change the oil and filter regularly (every 5,000 kilometers); frequently maintain the air filter and replace it periodically (every 20,000 kilometers); regularly clean the fuel system and replace the fuel filter (every 30,000 kilometers); maintain the radiator mesh (every 30,000 kilometers); and replace spark plugs (every 40,000 kilometers or based on driving conditions). The three major components of a car's warranty are: Engine, chassis, and transmission. An engine (Engine) is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), and electric motors. The term engine can refer to both the power-generating device and the entire machine including the power unit (e.g., gasoline engine, aircraft engine). The chassis refers to the combination of the transmission system, running gear, steering system, and braking system in a car. It supports and mounts the car's engine and its various components and assemblies, forming the overall shape of the car, bearing the engine's power, and ensuring normal operation. The transmission mainly refers to the car's gearbox. It is divided into manual and automatic types. A manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations. An automatic transmission (AT) consists of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.
