Injector Working Principle Database

The Caterpillar 387-9428 injector operates through a high-pressure common rail fuel injection system.

Operating Process

High-pressure fuel is delivered from the fuel pump.

Fuel enters the common rail accumulator.

Engine ECU controls injector timing electronically.

Solenoid valve opens precisely.

Fuel passes through precision nozzle holes.

Fuel atomizes into microscopic droplets.

Combustion efficiency increases.

Emissions decrease.

Power output improves.

Benefits

Better fuel economy

Reduced smoke emissions

Improved cold start performance

Enhanced combustion efficiency

Lower engine noise
