A typical fuel injector can be seen to be two basic parts, the nozzle and the nozzle holder or body. The highpressure 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 ...
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
