312-8339
Radiator Model 312-8339 is specifically designed for the CAT 320D Excavator. Aftercoolers serve in internal combustion engines to enhance efficiency, power output, and overall performance. Specifically, they cool the compressed air from the turbocharger—boosting the air's density and oxygen content prior to it entering the combustion chambers.
Features
Enhances combustion efficiency and boosts the engine's power output.
Prevents pre-ignition or knocking—issues that can cause damage to the engine.
Improves the combustion process, resulting in lower emissions and better fuel effciency.
Reduces intake air temperature to ease stress on engine components and extend their lifespan.
