The difference between gasoline and diesel
Gasoline has low boiling points and easy gasification compared to diesel, while diesel has low self-fired temperatures。
Diesel machines use compressed air to increase air temperature, allowing air temperatures to exceed diesel self-combustion tests, at which time diesel, diesel spray and air blends are ignited。
Compared to petrol, diesel engines have the advantage of being cheaper, more economical and less malfunctioning because they do not have a ignition system. However, because of the stress of the operation, which requires high structural strength and rigidity of the parts involved, diesel engines are heavy and larger in size; the oil pumps and nozzles of diesel engines are expensive because of their high accuracy; in addition, diesel engines work rough and vibrate with high noise; diesel fuel is not easy to evaporate; and it is difficult to start in cold vehicles during winter。
Compared to diesel engines, the working method of petrol machines is to use the ignition system to ignite gasoline-air mixtures under relatively low pressure and then to act。
Owing to differences in working principles, diesel engines can be used at relatively low speeds to achieve a significant twirl, while petrol engines can move at a much faster rate than diesel engines to maximum twirl。
So diesel engines are used more in situations requiring low-speed large twists, such as heavy vehicles, ships, warships, tanks, etc. The more important reason is that diesel flash points are safer than gasoline。
Start-up diesel vehicles are better than petrol vehicles, and high-speed petrol vehicles are better than diesel vehicles。
Daily maintenance of diesel trucks is better than that of petrol vehicles, as there is no power-control equipment such as a ignition system. Extreme repairs and maintenance of petrol trucks are better than diesel trucks。
