One major advantage of a diesel generator is its high fuel efficiency. Compared with a gasoline generator, a diesel generator is much more fuel-efficient. Due to their higher compression ratio, they can extract more energy from the same amount of fuel. Diesel generators are more durable than gasoline generators and feature a much longer service life. Working mechanisms of diesel generators and gasoline generators are the same, that is, transforms fuel into kinetic energy. However, their practices are different. Diesel generator ignites fuel by compression, and the gasoline generator ignites fuel by spark. For diesel generators, air is compressed to high pressure, causing the temperature to rise. And then the fuel is then injected into the hot compressed air for ignition. This process is called compression ignition or auto-ignition. On the other hand, gasoline generators adopt a spark ignition system. Fuel and air are mixed, then ignited by the spark plug. The spark plug produces an el...
