Factors Affecting The Fuel Injection Quality of Generator Set Injectors

Mar. 23, 2022

What are the factors that endanger the fuel injection quality of the Volvo generator set injector? It is necessary to know that the poor fuel injection quality of the Volvo generator set injector will easily lead to poor mixture formation and incomplete combustion, which will lead to the output power of the generator set after startup. Drop, unstable speed, increased fuel consumption, black smoke from exhaust, easy to stop the Volvo generator set at low speed, and sometimes knocking sound and other undesirable phenomena. So what are the reasons for the poor fuel injection quality of Volvo generator set injectors?

Poor atomization of the Volvo generator set injector: the nozzle hole is worn, the carbon deposit is blocked or burned out. The needle valve and the needle valve body are not tightly sealed. The spring force that adjusts the fuel injection pressure is weakened or broken, so that the spray pressure is too low.


The spray shape of the Volvo generator set is wrong: the nozzle holes and shaft needles of the fuel injector are not uniformly worn or there is carbon deposits at the nozzle holes. The injection pressure is too high or too low.


The reason why the fuel injector of the Volvo generator set cannot be stopped quickly (oil dripping): the oil outlet valve is not closed tightly or the pressure relief ring of the oil outlet valve is worn. The needle valve does not seal with the needle valve body. The needle valve is glued to the carbon deposit or stuck in the open position. The elastic force of the spring that adjusts the fuel injection pressure is weakened or broken, so that the fuel injection pressure is too low.
