WORKING PRINCIPLE OF 20R-1269 INJECTOR
The Caterpillar 20R-1269 injector functions as a high-pressure fuel metering and atomization device. Fuel supplied from the fuel gallery enters the injector body where pressure is generated through the fuel system.
The injector nozzle converts liquid diesel fuel into finely atomized particles. These microscopic fuel droplets mix efficiently with compressed air inside the combustion chamber, resulting in complete combustion, maximum power output, lower emissions, and improved fuel economy.
The injector opening pressure, spray pattern, injection timing, and fuel quantity are engineered to Caterpillar factory specifications.
Key operating stages include:
Fuel charging
Pressure generation
Needle valve opening
Fuel atomization
Combustion injection
Needle valve closing
