Abstract: One exemplary embodiment of the present disclosure relates to an engine intake port structure. According to the engine intake port structure of the exemplary embodiment of the present disclosure, a chamfer is formed to be offset to either side from an end corner of an intake port. Accordingly, the inflow of a fuel gas is concentrated on a side in which an opening width of the chamfer is wide at the beginning of an opening stage when the intake port is opened/closed by a valve unit, and after the intake port is opened, the opening width is formed to be similar at four sides of the valve unit such that swirls formed in the fuel gas is weakened. That is, complete combustion of the fuel can be anticipated since the length of time during which the fuel gas remains in a combustion chamber is extended.

Abstract: An internal combustion engine having a variable valve timing mechanism with a hydraulic control that is mounted on the front of the cylinder head for ease of accessibility and for ease of conversion of the existing engine. The engine includes an oil filter, oil cooler, and coolant pump, which are disposed and driven in a way so as to maintain short flow paths and permit internal conduits to be formed in the engine so as to avoid the possibility of leakage. The variable valve timing mechanism is controlled by hydraulic pressure supplied by the lubricating system, and a control valve assembly is mounted on the cover for the variable valve timing mechanism with the control passages being formed integrally in this cover. In addition, one of the timing chains may be easily accessed for adjustment without removing the cover through the removal of a bolt that holds an accessory mounting bracket to the engine.

Abstract: A unitary cylinder head assembly for a five-valve per cylinder internal combustion engine. The cylinder head assembly has upstanding walls that form tappet receiving bores for receiving the tappets that operate the respective valves. In addition, these walls provide bearing surfaces for a pair of camshafts, one of which actuates one set of valves and the other of which actuates another set of valves. The threaded fastening means for affixing the cylinder head to the cylinder block are disposed axially beyond the walls and in the case of the set containing the greater number of valves transversely outwardly from the walls. However, the threaded fastening means are disposed so that they are equal distance from the associated cylinder bore axis.

Abstract: An engine which employs a cam follower mechanism to reduce wear and reduce the size of an assembled engine. The cam follower mechanism utilizes guide rails located to reduce side thrust on the valve stem. The engine employs a high speed quill shaft to synchronize independent cam shafts existing in each of a plurality of interconnected engines. The engine is assembled using a single size fastener to provide a uniform stress gradient within the engine. The engines are interconnected utilizing O-ring seals. The engine provides a piston crown utilizing a connecting rod directly connected to the bottom surface of the piston crown. The piston crown is stabilized along the longitudinal cylinder axis by a rail guide. Connecting rods are provided which require less than one hundred eighty degrees (180.degree.) circumference of a crankshaft pin for support so that a plurality of connecting rods can be associated with a single crankshaft pin. A tabbed bearing fits under the plurality of connecting rods to provide lubrication between the connecting rods and the crankshaft pin. Connecting rods are held to the crankshaft pin by a circular retaining ring. The engine provides a separate cylinder head and cylinder which are attached via a circular deformable retaining band to form a metal to metal seal. The engine provides an independent lubrication system in each engine. Coolant or lubricant is provided to each engine in parallel so that the temperature of the coolant entering each engine is the same. A large diameter modular crankshaft is provided.

Abstract: A valve train for internal combustion engines utilizing an inverted bucket tappet with a pivot structure operatively disposed between the tappet and the end of the valve stem allowing the valves to be angulated with respect to each other and to the axis of the cylinder in both the transversal and the horizontal planes of the engine. Accordingly on a multi-valve engine, the valves extend radially from the associated combustion chamber to open and increase space in the center of the cylinder head for spark plugs, injectors, or pre-combustion chambers and so that the combustion chamber can be designed with a hemispherical surface, with tangentially disposed valve heads. The construction allows the use of large valves in conjunction with stronger, better-cooled valve seats and bridges. The tappets can be actuated conventionally by direct-acting overhead camshafts, or by rocker arms and "T" bridges.
