The technical level of the diesel generator set is originally closely related to the skill level of the diesel engine. The trade-off and evaluation of the function of the diesel generator set also regards the diesel engine as a critical content, because the usual use of care and regular labor, the focus is on diesel. Engine, so a well-functioning diesel engine is the basic strength of contemporary generator sets.
The overseas diesel generator sets use diesel engine power Daewoo 50KW. They all use turbocharged technology to improve the specific power. At the same time, there are different intercooling skills. The multi-valve technology is combined to further deepen the specific power of the diesel engine. Up to 1.98kg/kw, and the ordinary diesel engine has a specific quality of 8.0-20kg/kw.
It can be seen that the resolution is disparity. Due to the deepening of the specific power, the raw material functions of the intake system, the fuel supply system, the piston group and the crankshaft connecting rod structure must be continuously improved and improved. The production process level is also put forward higher requirements. Ordinary use of high-speed diesel engines, medium and small power has been below 2000KW units) widely used high-speed diesel engines, from the situation of the units ordered around the world in the past decade, 80% of the diesel engine with a speed of 1500r / min, so that the function of the combination of the machine is raised high.
The use of EFI technology, electronic governor, and electronic hydraulic governor increased the power quality of the unit and reduced the pollution of the exhaust to the environment. The dual-fuel technology was used to design the diesel engine fuel system to use both diesel and diesel. It can also use natural gas to improve its adaptability. It has high precision and is close to zero production. It has good mechanical function. The first overhaul operation time is 25000-30000 hours, usually less than 20,000 hours.
The high-pressure common rail fuel supply system is adopted. After careful electronic fuel-emission device, it can control the fuel injection time, fuel injection quantity and fuel injection pressure to reach the maximum control of diesel engine fuel noise, and it is useful to control the diesel engine’s non-product gas emission. And can achieve obvious economic benefits, reducing fuel consumption.
