Embodiment Construction

[0027] Preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0028] Such as Figure 1 to Figure 3 As shown, the engine 1 consists of a single cylinder engine comprising an engine body 2 with a rearwardly inclined cylinder axis. The engine main body 2 includes: a crankcase 4, which internally defines a crankcase chamber 3; The cylinder 5 communicated with the chamber 3; the cylinder head 7, which is connected to the upper end of the cylinder block 6 and closes the upper end of the cylinder 5; and the head cover 9, which is connected to the cylinder head 7 to define valves together with the cylinder head actuation chamber. A transversely extending crankshaft 10 is rotatably supported by the crankcase 4 and a piston 13 connected to the crankshaft 10 via a connecting rod 12 is accommodated in the cylinder 5 for reciprocating movement along the cylinder axis in a manner known per se. A plurality of legs 14 are provided ...

Abstract

An air cleaner (32) comprises a base member (41) including a base wall (41A) extending substantially horizontally, and a cover member (42) attached to an upper side of the base wall to jointly definea filter chamber (70) for receiving a filter element (43) therein. The air cleaner further includes a passage member (44) communicating with the filter chamber and incorporated with a plurality of airejection pipes (44C) each surrounded by an annular air inlet passage (44E) fitted with guide vanes (44D) for rotating the air flow, and a case member (45) defining separation chambers (45C) for separating dust from the rotating air flow. The passage member (44) is interposed between the cover member (42) and the case member (45).

Description

technical field [0001] The present invention relates to an air cleaner for an internal combustion engine, in particular to an air cleaner provided with a plurality of cyclone dust collection units and filter dust collection units. Background technique [0002] A known air cleaner for an internal combustion engine is provided with a cyclone dust collection unit and a filter dust collection unit which are connected in series in such a way that in the cyclone dust collection unit there will be Dust with a relatively large particle diameter is removed from the intake air, and then the intake air discharged from the cyclone dust collection unit is conveyed to the filter dust collection unit to remove dust with a relatively small particle diameter from the conveyed intake air. See, for example, JPS61-108861A. According to this arrangement, clogging of the filter element in the filter dust collection unit is reduced, and thus the interval for replacing the filter element can be ex...
