Abstract
An engine enclosure (100, 200) for an agricultural work vehicle has a plurality of walls (114, 210, 216, 218, 230) that surround an internal combustion engine (102, 202) and a fan (122, 236) coupled to an air inlet (120, 238) in the plurality of walls for maintaining the inside of the engine enclosure (100, 200) at a pressure slightly higher than atmospheric pressure.

An engine enclosure (100, 200) for an internal combustion engine (102, 202) comprises a plurality of walls (114, 210, 216, 218, 230) surrounding the internal combustion engine (102, 202), wherein the walls define an air inlet (120, 238) opening into a space between the internal combustion engine (102, 202) and the plurality of walls (114, 210, 216, 218, 230), and the fan (122, 236) coupled to the air inlet (120, 238) to provide air under pressure to the space between the internal combustion engine (102, 202) and the plurality of walls (114, 210, 216, 218, 230), and to maintain the air in the space at a pressure above the air pressure outside the plurality of walls (114, 210, 216, 218, 230).
