Working Principle of Caterpillar 20R-1280 Fuel Injector
The Caterpillar 20R-1280 injector functions as a high-precision fuel metering and atomization device within the engine's electronic fuel injection system.
Fuel enters the injector body under high pressure through the fuel supply circuit. The injector's internal valve assembly precisely controls fuel flow according to engine operating conditions and ECM commands.
When injection timing is initiated, fuel passes through the injector nozzle and is atomized into microscopic droplets. This process dramatically increases the fuel's surface area, enabling rapid mixing with compressed air inside the combustion chamber.
