A typical fuel injector can be seen to be two basic parts, the nozzle and the nozzle holder or body. The high-pressure fuel enters and travels down a passage in the body and then into a passage in the nozzle, ending finally in a chamber surrounding the needle valve. The needle valve is held closed on a mitred seat by an intermediate spindle and ...

Jun 14, 1977· This invention relates to a fuel injection pump for Diesel engines capable of controlling the beginning and rate of fuel injection in response to variations in engine load and speed, thereby to abate the noise due to irregular combustion and reduce pollutants in the exhaust gases during part load operation as well as in idling.
fuel injection systems. As a critical component of the diesel fuel injection system, it’s the nozzle’s function to atomize fuel under extreme pressures (up to 26,000 psi) to ensure perfect combustion, exact emissions and peak engine performance. On average, each nozzle fires 1,000 times per minute, so precision design and durability are key
