Abstract
An assembly of auxiliary apparatus for an internal combustion engine includes a coolant pump, an oil cooler device, and an oil filter unit combined and interconnected as a unitary unit for mounting on the internal combustion engine. The oil cooler device includes a housing having an oil pathway and a coolant pathway formed therein. The pathways are arranged to allow heat exchange between oil and coolant flowing through the pathways. The housing has a mounting surface for attachment to the internal combustion engine such that the oil pathway and the coolant pathway both extend beyond the mounting surface and into a recess of a wall of the engine. The assembly allows the engine envelope size to be reduced.
Claims18
An auxiliary assembly for an internal combustion engine, said auxiliary assembly comprising:
- a coolant pump, an oil cooler device and an oil filter unit combined and interconnected as a single unitary unit for mounting on the internal combustion engine, wherein said oil cooler device comprises a housing having an oil pathway and a coolant pathway formed therein, wherein said housing has a mounting surface for attachment to the internal combustion engine, and wherein the oil pathway and the coolant pathway each extend beyond the mounting surface.
A unitary base structure for mounting an oil cooler device, an oil filter unit and a coolant pump on an internal combustion engine, said base structure comprising:
- a housing for at least partially enclosing, in a spaced relationship thereto, an oil cooler element;
- a first device being formed integrally with said housing and including a part of the coolant pump;
- and a second device being formed integrally with said housing and including a filter head for the filter unit, the first and second devices being located closely adjacent to each other on the unitary base structure.
An internal combustion engine comprising:
- (A) an engine block including a wall having a recess formed therein;
- and
- (B) an auxiliary apparatus mounted on said wall and comprising a coolant pump, an oil cooler device, and an oil filter unit combined as a single unitary unit, wherein
- (1) said oil cooler device comprises a housing having an oil pathway and a coolant pathway formed therein,
- (2) said housing includes a mounting surface for attachment to said wall of said engine block, and wherein
- (3) said oil pathway and said coolant pathway both extend beyond said mounting surface to said recess in said wall.
