Although the existing problems in the use of diesel vehicles, but this is caused by inadequate technical level, rather than the nature of the diesel engine, it can be solved through technological progress. So, including home cars, diesel engines are a trend
At the same time, the fuel supply system of diesel engines is relatively simple, so the reliability of diesel engines is better than that of gasoline engines. The diesel engine has a high compression ratio because it is not limited by deflagration and the need for spontaneous combustion of diesel fuel.
Second, the load of freight cars consumes more natural fuel, and diesel engines are more fuel-efficient than gasoline engines. Because the heat efficiency of diesel is 15% higher than that of gasoline vehicles, the average fuel economy of diesel engines is 30% compared with that of gasoline engines.
First of all, the most important thing is that the diesel engine has large torque, large vibration, high gasoline engine speed and small vibration. These characteristics fully meet the needs of the truck, because the truck is often suitable for harsh conditions in the operation of the environment, the need for full load work for a long time, the general load is relatively large. Can also be simply understood as diesel engine strength.
