Abstract
An engine includes a starter motor and a filter, both of which are positioned to a side of a cylinder that faces an exhaust port with respect to a direction that is perpendicular to both a reciprocating direction of a piston and an axial direction of a crankshaft. Moreover, the starter motor is positioned to a side of the cylinder that faces a crankcase, and the filter is positioned to a side of the starter motor that faces a cylinder head, with respect to the reciprocating direction of the piston.
Claims6
An engine comprising:
- a crankshaft which converts a reciprocal motion of a piston to produce a rotary motion;
- a crankcase supporting the crankshaft;
- a cylinder extending from the crankcase to protrude in a reciprocating direction of the piston;
- a cylinder head coupled to a protruding end of the cylinder;
- a starter motor which rotates the crankshaft to initiate an operation of the engine;
- a filter which filters a lubricant fluid circulating through the engine;
- and
- an air intake port and an exhaust port defined in one and the other of opposite sides of the cylinder head, respectively, in a direction perpendicular to both a reciprocating direction of the piston and an axial direction of the crankshaft, wherein
- the starter motor and the filter are positioned to a side of the cylinder that faces the exhaust port with respect to the perpendicular direction,
- the starter motor is positioned to a side of the cylinder that faces the crankcase, and the filter is positioned to a side of the starter motor that faces the cylinder head, with respect to the reciprocating direction of the piston.
