What is a diesel engine?

Diesel generator setsThe diesel engine used is a power output portion. It is done with high temperature high pressure air injected into the inserted mist-like diesel in the cylinder, and converts thermal energy into mechanical energy. Since the diesel is ignited by the compressed high temperature air, the diesel engine is also referred to as a compressed povered internal combustion engine. Diesel engines used in diesel generator groups are generally four stroke water-cooled high-speed diesel engines. The so-called four-stroke diesel engine is intake, compressed, done (expansion), and four processes of exhaust, complete a work cycle diesel engine.
Various types of visual machines, the classification methods can also be divided into single cylinders and multi-cylinder diesel engines according to the form of the body structure, where the multi-cylinder diesel engine is divided into a straight-oriented and V-shaped arrangement; The intake method is divided into self-combustible intake and boost type; divided into two strokes and four strokes according to the working cycle process; according to the cooling method, it can be divided into power generation, marine, vehicle according to the purpose. , Agricultural irrigation, engineering machinery and other industrial supporting diesel engines; the rated speed is divided into high speed (rated speed at 1000R / min), medium speed (rated speed is within 600 ~ 1000R / min) and low speed (rated speed) Under 600R / min), the rated speed of the diesel engine used in diesel generator sets is generally 1500r / min or 3000 r / min.
The generator set is much more, and the power is different, in which the large generator sets are mostly diesel, the power generator set is typically fuel with gasoline.
The diesel generator set with diesel engine as a power generator is multi-purpose advantages compared to gasoline generator sets as generator power source:
○ 1 Fuel economy. The diesel engine is high, the fuel consumption rate is low, and when the working condition changes, the fuel pump curve changes are relatively flat, which is very important for diesel engines that are often working under partial load.
○ 2 is reliable and durable. Diesel engine has no ignition system, so the fault is relatively small, and the work reliability is high.
○ 3 is wide.
○ 4 There is less harmful emissions.
○ 5 Good fire safety.
