Diesel engine nozzle is an integral part of diesel engine fuel supply system , its performance will directly affect the power, economy and reliability of diesel engines. Proper maintenance is the nozzle normal work and extend the life of an important prerequisite .
Following is a brief introduction, five major elements about aspect of life impact nozzle , to ensure a diesel engine at normal working temperatures :
( 1 ) Do not allow the engine to idle time . When prolonged idling , the engine speed is low, the fuel pump speed is low , injection pressure decreases, will result in poor atomization of diesel combustion poor indoor air quality hybrid , fuel is injected into the combustion is not complete, the formation of coke . Coke easy to nozzle clogging , more diesel fuel atomization quality is bad, causing the engine power down, exhaust black smoke , but also accelerated the damage to the fuel injector .
( 2 ) Do not overload the engine for a long time , to prevent the body from overheating and even pieces of the injector needle stuck , tests showed that when the engine speed constant while the load increased by 2 -fold increase in engine wear is also nearly 2 times .
( 3 ) Ensure that the engine lubrication system technology cooling system in good condition . If the engine cooling , poor lubrication , can easily cause the engine to overheat ,
Thereby accelerating nozzle damage , reducing its service life.
( 4 ) Ensure that the engine exterior cleaning .
( 5 ) In the engine to avoid prolonged high temperature environment .
