How many more years can China V diesel vehicles run?
1 Answers
With the implementation of the China VI standard, China V diesel vehicles are not affected in normal use, and there are no restrictions or bans on their operation. They can continue to be driven indefinitely. Below is an introduction to diesel engines: 1. Advantages: Diesel engines offer high torque and excellent fuel efficiency. The working process of a diesel engine shares many similarities with that of a gasoline engine, with each working cycle also going through four strokes: intake, compression, power, and exhaust. However, since diesel engines use diesel fuel, which has higher viscosity and lower volatility compared to gasoline, and a lower auto-ignition temperature, the formation of the combustible mixture and the ignition method differ from those of gasoline engines. 2. Differences: In diesel engines, the mixture in the cylinder ignites through compression. During operation, only air enters the cylinder. When the air in the cylinder is compressed to its maximum, the temperature can reach 500-700°C, and the pressure can reach 40-50 atmospheres. As the piston approaches top dead center, the fuel injection nozzle of the supply system injects fuel into the combustion chamber at extremely high pressure within a very short time. The diesel forms fine droplets, mixes with the high-pressure and high-temperature air, and the combustible mixture ignites spontaneously, expanding violently to produce explosive force, which pushes the piston downward to perform work.
