An engine compartment of a fork-lift truck has a noise-proof bottom plate for shielding the compartment bottom, and lateral intake air ports and passages for admitting outside air to the engine compartment, the incoming air being drawn over the walls of an hydraulic working oil tank mounted adjacent to the engine compartment, to continuously cool the oil within the tank. Introduction of the air through intake ports formed in the side of the truck body prevents entry of dust, splashing water and the like from the ground beneath the truck. The noise-proof bottom plate also serves to suppress noise emissions from the engine. A variety of air intake passage arrangements are described.

A fork-lift truck having an internal engine compartment bounded on one side by a tank for hydraulic fluid, said tank having top, bottom and side walls, and said compartment being bounded by additional walls including a bottom plate, the latter shielding said compartment from dust and reducing emission of engine noise, said tank having one of said side walls facing out of said truck on one side of said truck, said truck further comprising: means defining a substantially horizontal and horizontally elongated intake port adjacent said hydraulic fluid tank external to said engine compartment on the outside of said truck extending along said one side of said truck in the front-to-back direction along substantially the entire front-to-back length of said tank for admitting outside air; and means including at least one of said top, bottom and said one side wall of said hydraulic tank for defining a passage between said intake port defining means and the interior of said engine compartment for conveying outside air from said intake port to the interior of said engine compartment in contact with substantially the entire length of a lengthwise extending wall of said hydraulic fluid tank for cooling said hydraulic fluid in addition to an engine in said engine compartment.
