Diesel engines operate by compression ignition while gasoline engines operate on spark ignition. In diesel generator air is drawn into the engine, which results in greater compression-warming. The engine temperature increases, which is much higher than the temperature reached a petrol engine. At the height of the temperature and pressure, ignites the diesel engine is left as regards temperature extremes.
The air and fuel are infused into the diesel generator at various stages during a gas generator of an air and gas mixture are introduced. In diesel engines, the fuel is injected through a nozzle as a carburetor is used for gasoline engines. diesel generator compresses air and the proportion is much higher. Diesel generators compresses in a ratio of 14: 1 to 25: 1, whereas gasoline has a compression ratio of 8: 1 and 12: 1. In particular air cooled and liquid cooled engines are variants to be selected as appropriate. Benefits of diesel generators:
Diesel generators are much better and effective and, compared with a petrol engine. Some of the reasons are the following:
The old diesel generators models have higher noise and higher maintenance costs. But modern diesel engines require less maintenance and are quiet compared with gas engines.
They are the most robust and reliable
The cost of fuel per kilowatt diesel engine is thirty to fifty percent lower than gas engines.
The absence of spark plugs or spark son reduced maintenance costs.
Diesel engine is 1800 rpm water cooled engine running for 12,000 to 30,000 hours before major maintenance is required. Gas burns more than diesel, so they have a shorter life compared to diesel units.
