Injector Working Principle

The Cummins 4914328 injector operates as a precision fuel metering device responsible for delivering atomized diesel fuel directly into the combustion chamber.

Operating Sequence

Fuel is supplied from the PT fuel pump.

Injector receives pressurized fuel.

Internal plunger and nozzle assembly control injection timing.

Fuel is atomized through precision-machined nozzle holes.

Atomized fuel mixes with compressed air.

Combustion generates engine power.

Excess fuel returns to the fuel circuit.

Benefits

Improved combustion efficiency

Reduced fuel consumption

Lower exhaust emissions

Increased engine power output

Extended engine life

Stable cold starting performance
