Claims15
An internal combustion engine of which a cylinder is slanted toward a crankcase, the engine having a combustion chamber, said combustion chamber disposed inside said cylinder and capped by a cylinder head comprising:
- intake and exhaust valves provided in said cylinder head and below said combustion chamber;
- a camshaft provided below said intake and exhaust valves for driving said intake and exhaust valves through a rocker arm;
- and
- wherein said rocker arm having a first end and a second end opposite said first end, the first end making contact with said intake and exhaust valves and the second end making contact with said camshaft.
An internal combustion engine of which a cylinder is slanted toward a crankcase, the engine having a combustion chamber, said combustion chamber being disposed inside said cylinder and capped by a cylinder head comprising:
- intake and exhaust valves provided in said cylinder head and communicating with said combustion chamber;
- a camshaft provided below said intake and exhaust valves for driving said intake and exhaust valves through a rocker arm;
- a camshaft driving means for driving said camshaft;
- a casing for enclosing said camshaft driving means;
- and
- an air vent provided at a central part of said casing for directing air toward the cylinder.
An internal combustion engine (1) having, a cylinder (3), a cylinder head (10) mounted on and capping said cylinder (3), a combustion chamber (10a) located in said cylinder (3) for receiving a reciprocating piston (7), a crankshaft for driving the piston (7) in reciprocating fashion, and a crankcase (2) provided below said cylinder (3) for enclosing the crankshaft (6), comprising:
- intake and exhaust valves (11) communicating with said combustion chamber (10a);
- an endless belt (19), and a camshaft (14) driven by said crankshaft (6) via said endless belt (19), said camshaft (14) located below said intake and exhaust valves (11);
- a rocker arm (15) for actuating an opening and closing of said intake and exhaust valves (11), the rocker arm (15) being driven by the camshaft (14);
- and
- a casing (17) covering an entire outer periphery of said endless belt (19), the casing having an opening for effectively inducing a cool air to said internal combustion engine (1), wherein a center line (Lc) of said combustion chamber (10a) is slanted relative to a horizontal line at a predetermined angle, thereby to reduce the height of said internal combustion engine (1).
