TM 9-2320-365-10 1-15. ENGINE AIR INTAKE SYSTEM Figure 1-10. Engine Air Intake System The Engine Air Intake System consists of a dry-type intake air cleaner (1, Figure 1-10), turbocharger (2), and a Charge Air Cooler (CAC) (3). The turbocharger increases engine horsepower by delivering a higher volume of air to the engine. The turbocharger compresses the air and delivers it to the CAC. The air flows through the CAC which cools the air before it is delivered to the engine cylinders. The air aspiration tubes (4) pass the cooled and compressed air to the engine inlet manifold (5). The compressed air/fuel mixture allows more complete burning of the fuel. The result is an increase in horsepower and lower emissions. 1-34
