Caterpillar fuel injectors are a critical component of any Caterpillar engine. They are responsible for injecting the precise amount of fuel into the combustion chamber at the right time, which is essential for optimal engine performance.
How Caterpillar Fuel Injectors Work
Cat injectors are typically unit injectors. This means that the injector contains all of the components necessary to inject fuel, including a plunger, a nozzle, and a solenoid valve.
The plunger is a piston that is driven by the camshaft. As the camshaft rotates, it raises the plunger, which creates high pressure in the injector. The nozzle is located at the top of the injector and is responsible for atomizing the fuel and spraying it into the combustion chamber. The solenoid valve controls the flow of fuel to the injector.
