The discharge shape on mechanical fuel injection systems is achieved by using:
A)a stepped-camshaft"
B)buttons in the injection pump"
C)a stepped-type nozzle valve
D)a hydraulic control valve"

Question

Quizplus · Accepted Answer

A stepped-type nozzle valve is used to achieve the discharge shape on mechanical fuel injection systems. This is because the stepped-type nozzle valve has a different cross-sectional area at different points along its length, which causes the fuel to flow at different rates through the valve. This results in a discharge shape that is tailored to the specific requirements of the engine.
