Air handling system for engines

摘要

A skid steer loader has an engine compartment that is enclosed with walls, and an engine mounted in the engine compartment. The engine has components such as an exhaust manifold and a muffler inside the engine compartment which can get quite hot under certain operating conditions. A radial fan is provided for withdrawing air from the engine compartment and discharging it to ambient conditions to reduce the temperature in the engine compartment. The fan is in a housing that has apertures that directs air under pressure against the exhaust manifold and muffler and other hot components of the engine to reduce the maximum temperature such components reach.
