Abstract
A side valve internal combustion engine provided with at least one combustion cylinder having a piston. At least two intake valves and at least one exhaust valve are provided for each of the combustion cylinders. In order to maintain a compact engine and provide a nozzle-type combustion chamber, the intake valves and exhaust valve are locate to one side of the combustion chamber in the engine block. The exhaust valve is further located at a greater distance from the combustion cylinder than the intake valves in order to decrease heat distribution on the cylinder walls. The nozzle-type chamber provides for efficient flow of gases within the engine.
Claims41
A side valve engine comprising, at least one combustion cylinder accommodating a piston driving a crankshaft, and a cylinder head, wherein each said combustion cylinder has two intake valves communicating with respective intake ports and an exhaust valve communicating with an exhaust port, said exhaust valve being located further away from the combustion cylinder than either of said intake valves.
A method of making a side valve engine with a combustion cylinder, crankshaft and cylinder head, comprising;
- providing the combustion cylinder having two intake valves and an exhaust valve arranged to one radial side of the combustion cylinder, and
- securing a cylinder head with an igniter to the combustion cylinder.
A side valve engine comprising,
- at least one cylinder having a movable piston, and
- at least two intake valves being located to one side of each of the at least one cylinder.
An internal combustion engine, comprising;
- an engine block,
- a cylinder being located in the engine block and having at least one piston moveable therein,
- a cylinder head being mounted on the engine block and defining a combustion chamber,
- at least two intake ports being arranged in the engine block to one side of the cylinder, and
- intake valves being arranged to operatively open a respective intake port into the combustion chamber,
- wherein the engine block has a surface arranged at the one side of the cylinder, and
- wherein the intake valves and an exhaust valve are arranged on the surface of the engine block.
An internal combustion engine, comprising;
- an engine block having at least one cylinder with a piston movable therein,
- a cylinder head mounted on the engine block and defining a combustion chamber for the at least one cylinder,
- at least two corresponding inlet ports operatively supplying an air/fuel mixture to the corresponding combustion chamber, and
- at least one respective exhaust port operatively conveying exhaust gases from the corresponding combustion chamber,
- wherein the inlet ports and the exhaust port are arranged laterally to the at least one cylinder.
A side valve internal combustion engine, comprising;
- a cylinder having a movable piston,
- at one end of the cylinder a cylinder head being arranged to form a combustion chamber,
- the cylinder having a radial cross-section at said one end,
- at least two inlet ports operatively supplying working fluid to the combustion chamber via respective inlet valves, and
- at least one exhaust port operatively conveying exhaust gas from the combustion chamber via an exhaust valve,
- wherein respective ends of the at least two inlet ports at the respective inlet valves are arranged laterally to the radial cross-section of the cylinder.
A method of operating an engine having at least one cylinder with a movable piston, comprising;
- supplying an air/fuel mixture from at least two intake valves into a combustion chamber associated with the at least one cylinder,
- combusting said air/fuel mixture, and
- conveying exhaust gases through an exhaust valve,
- wherein the intake valves and exhaust valve are arranged at a lateral side of the cylinder.
