摘要:
An engine where a crankshaft (12) and a camshaft (36) are connected by a timing transmission device (37) composed of a drive rotation member (45), a driven rotation member (46), and an endless transmission member (47), a working window (55) for attaching and detaching the driven rotation member (46) to and from the cam shaft (36) is opened in an outer end surface (5c) of a cylinder head (5), and a lid body (57) for closing the working window (55) is joined to the outer end surface. The outer end surface (5c), to which the lid body (57) is joined, of the cylinder head (5) is the inclined surface (5c) inclined such that that outer peripheral section of the driven rotation member (46) which is on the opposite side of the drive rotation member (45) is exposed from the working window (55). The construction improves workability in installation of the endless transmission member on the driven rotation member, installation of the driven rotation member on the camshaft, etc., and in addition, the construction contributes to downsizing of the engine.

A housing (10) for abating noise and receiving an air cleaner (40) is disclosed. The housing (10) is configured for separable coupling to an internal combustion engine (98) of an automobile. The engine (98) includes a plurality of belt driven accessories (150) driven by a crankshaft. The housing includes an internal air cavity (30) disposed in the housing. The cavity (30) provides an air induction chamber adjacent (24) an intake for inducing air into the air induction chamber (24) from an external source and a filtering chamber (28) adjacent an air discharge for venting air from the filtering chamber (28). The filtering chamber (28) is configured to receive a filter (40) for purifying air disposed intermediate the intake and the discharge. The engine (98) further includes a shroud integral with the exterior of the housing. The shroud (58) provides a peripheral wall defining a recess configured to at least partially surround at least a portion of at least two belt driven accessories. The shroud (58) substantially reduces noise generated by the engine (98).
摘要:
An oil pump is provided. The oil pump comprises a shell, a rotor mounting part on the shell, and a rotor mechanism disposed on the rotor mounting part. The shell has an inlet and an outlet and defines a low-pressure oil chamber and a high-pressure oil chamber therein. A buffer chamber is defined between the low-pressure oil chamber and the high-pressure oil chamber, and a barrier wall is disposed between the buffer chamber and the low-pressure oil chamber. An engine cover comprising the oil pump and an engine comprising the engine cover are also provided.
