Engine enclosure
First Claim
1. An engine enclosure comprised of a hood having a baffle secured thereto to provide air passages between the hood and bafflethe hood having adjoining front, left and right side and top members, the front member including an inlet opening therein, the baffle operatively being attached to the inside of the hood and including adjoining front, left and right side and top surfaces, said side surfaces including a generally triangularly shaped portion therein, each of which surfaces are in closely spaced relationship with the respective front, left and right side and top members of the hood to form first, second and third air passages therewith, said first passage being formed between the front member and front surface, said second passage being formed between one side member and side surface and the third passage being formed between the top member and top surface, and the top surface includes an air outlet opening through which air received from the inlet opening of the front member and moved along the first, second and third passages can be exhausted.

Abstract
A modular engine enclosure comprised of a hood and baffle is provided to channel cooling air along passages formed between their adjacent surfaces to the radiator of a water cooled engine. The passages provide acoustic air barriers and along with selected enclosure surfaces covered with sound absorbing foam, serve to contain engine sounds within the enclosure. The passages receive air from a generally upright inlet opening and direct it evenly over the top surface of the horizontally oriented radiator. After being drawn through the radiator, the air is exhausted generally horizontally out the back of the engine compartment. The modular construction of the enclosure allows it to be easily raised and/or removed so that maintenance and service activities can be performed on the engine and its components.

15. An engine enclosure comprising a hood having a baffle operatively coupled therewith to provide air passages between the hood and baffle,
the hood including a top member, a front member with an inlet opening therein, left and right side members attached to the top and front members and extending back from the front member, the baffle operatively mounted within the hood to form therewith passages for receiving air from the inlet opening in the front member, said baffle having a first generally upright surface in closely spaced relationship with the front member and the inlet opening of the hood to provide a first air passage between the front member and the upright surface, left and right side surfaces extending laterally from the upright surface of the baffle, said side surfaces including a generally triangularly shaped portion therein and being in closely spaced relationship with the respective left and right members of the hood to provide second air passages between said side members and side surfaces, and a top surface coupled with the upright, left and right side surfaces of the baffle and extending laterally to form a third air passage with the top member, said top surface including a vertical opening therein for permitting air which has been received from the inlet opening of the hood and moved along the first, second and third air passages to pass therethrough.

26. An engine enclosure comprised of
a hood with adjoining front, side and top members, the front member including an inlet opening therein, a baffle attached to the inside of the hood and including adjoining front, side and top surfaces, said side surface including a generally triangularly shaped portion therein, each of which surfaces are in closely spaced relationship with the respective front, left and right side and top members of the hood, said baffle and hood being in registry with one another to form an air passage therebetween, said passage being formed between the front member and front surface, the top member and top surface and the respective side members and side surfaces, and the top surface includes an air outlet opening through which air received through the inlet opening of the front member can be moved along the air passage and to and through the outlet opening in the top surface.
