The technical level of the diesel generator set we are talking about is originally closely related to the technical level of the diesel engine. Weighing and evaluating the functions of the diesel generator set also takes the diesel engine as an important part. Because the common use of care and regular labor focuses on the diesel oil engine, so the diesel engine with good functions is the solid foundation of contemporary generator sets
Overseas diesel generator sets with diesel engine power of Daewoo 50KW are widely used to improve the specific power. At the same time, there are different intercooling technologies. The integration of multi valve technology further deepens the specific power of diesel engines, with the highest specific quality of 1.98kg/kw, while the specific quality of ordinary diesel engines is 8.0-20kg/kw
It can be seen that there is a huge difference in its resolution. Due to the deepening of specific power, the raw material functions of the air intake system, fuel supply system, piston set, crankshaft and connecting rod organizations should be constantly improved and improved. Higher requirements have also been put forward for the level of manufacturing technology. High speed diesel engines are commonly used, and small and medium power units have reached 2000KW.) High speed diesel engines are widely used. From the situation of units ordered around the world in the past decade, 80% of the engine is a diesel engine with a speed of 1500r/min, which improves the function of engine block
The electronic injection technology, electronic governor and electronic hydraulic governor are selected to improve the power supply quality of the unit and reduce the pollution of exhaust to the environment. The dual fuel technology is selected to design the diesel engine fuel system to be able to use both diesel and natural gas to improve its adaptability. The precision is high, it is made close to the zero handyman, and the mechanical function is good. The first overhaul operation time is 25000-30000 hours, usually the unit is within 20000 hours
High pressure common rail fuel supply system is selected. Through careful electronic control fuel radiation device, the fuel injection time, fuel injection volume and fuel injection pressure can be controlled freely to reach the goal of maximum control to reduce diesel engine fuel noise and effectively control diesel engine emissions of unwanted gases, and obvious economic benefits can be achieved to reduce fuel delivery
