How Long Can National V Diesel Vehicles Continue to Be Driven?

[DeEllie]

With the implementation of the National VI standard, National V diesel vehicles are not affected in normal use, with no driving bans or restrictions. They can continue to be driven indefinitely. Details are as follows: 1. Advantages: Diesel engines offer high torque and excellent fuel efficiency. The working process of a diesel engine shares many similarities with gasoline engines, with each cycle also going through intake, compression, power, and exhaust strokes. However, since diesel fuel has higher viscosity than gasoline, is less volatile, and has a lower auto-ignition temperature, the formation of the combustible mixture and ignition method differ from gasoline engines. 2. Differences: The mixture in a diesel engine's cylinder is ignited by compression rather than spark. During operation, only air enters the cylinder. When compressed to the maximum, the air temperature can reach 500°C-700°C, and the pressure can reach 40-50 atmospheres.
