Is Annual Inspection Difficult for Household Diesel SUVs?
1 Answers
Annual inspection for household diesel SUVs is not troublesome, following the same process as gasoline vehicles. Annual Inspection Regulations: According to the latest clear regulations in China, non-operational passenger vehicles with 9 seats or fewer (including 9 seats), such as sedans and off-road vehicles, have a service life of 15 years. If they continue to be used after reaching the scrapping standard, they must undergo annual inspection twice a year starting from the 16th year. After exceeding 20 years, they must undergo annual inspection four times a year starting from the 21st year. Diesel Engine: The advantages of diesel engines are high torque and good economic performance. The working process of a diesel engine shares many similarities with a gasoline engine, with each working cycle also going through four strokes: intake, compression, power, and exhaust. However, since diesel engines use diesel as fuel, which has higher viscosity than gasoline and is less prone to evaporation, and its auto-ignition temperature is lower than gasoline, the formation of the combustible mixture and the ignition method differ from gasoline engines. The main difference is that the mixture in the cylinder of a diesel engine is ignited by compression rather than by spark.
