Noise silencer assembly

摘要

A noise silencer covering an air discharge opening in front of a radiator is used for noise control for an earthmoving vehicle. The silencer encloses a radiator grill which is removably attached to a forward end of an engine enclosure. The noise silencer is provided with upper and lower discharge openings with the open area of the upper opening being larger than that of the lower opening. The walls of the silencer are lined with sound absorbing materials.
