20kva diesel generator,20kva diesel generator engine set for sale

① diesel dirty, there are impurities in the high-pressure tubing, force a lonely spray curved a needle even wear member, the needle valve even pieces of closed lax anti-combustion chamber pressure gas channeling burned needle Couples. In addition, the dirt on the part of the fuel injector pressure regulator spring, tappet and so on through the injector tappet moved to the upper part of injector needle, or oil on the road to prevent oil spills cotton rope, lead wire into the high-pressure spray hose oil, will cause the needle stuck Couples.

② machine temperature is too high Defective cooling spray song, making tiger valves of stuck. And oil too late, too much cooling water scale or blockage, water pump impeller face wear, engine overload, etc. will make the long-term engine overheating.

③ the pumping valve wear, the fuel injector to stop fuel injection drip phenomenon occurs to cause the spray nozzle song coke coke combustion occurs stuck fault.

④ spray Qu pressure is too low, resulting in combustion chamber pressure gas channeling anti-;

When ⑤ injector installation, drain installation gasket or gasket damage caused by leak, causing the injector local temperature is too high and stuck

⑥ parts manufacturing reasons, such as the cylinder head fuel injector mounting hole injector with tight, needle valve body and the cylinder head mounting hole gap is too small, the cylinder head injector mounting hole too deep processing and so on.
