Fuel Injectors
The diesel fuel injector is a pressure valve fitted to
individual engine cylinders with operation pressure and flows calibrated for each particular model and make of engine. Injector components are designed to disperse fuel in a set pattern within the combustion chamber. Fuel injectors represent a high quality of workmanship, reliability and accuracy.
Operation is achieved by the injector body being connected by piping to the high-pressure fuel pump which delivers fuel under pressure to the injector. A drilled passage then conveys the pressurised fuel to the nozzle assembly. Construction of the nozzle consists of a nozzle valve and seat; the nozzle valve being the only moving part. A tight seal is created at the outlet by the valve being forced on to the seat by a strong spring.
When in operation the compression of the spring is overcome by hydraulic pressure at the correct angle of rotation of the engine. This is achieved by fuel delivered from the fuel pump. The importance for the fuel to be free from ontaminates cannot be [Read more...]
