Hybrid internal combustion reciprocating engine

A hybrid type reciprocating internal combustion engine comprising:

• a cylinder;
• a cylinder head mounted on the cylinder having a substantially planar inner surface;
• exhaust and inlet valves positioned in the head connected to corresponding exhaust and unthrottled inlet passages;
• a piston reciprocally mounted within the cylinder having a top surface thereon which surface in the top dead center position of the piston is in close proximity with the inner surface of the head;
• a precombustion chamber located in the head;
• a lineal passage tangentially joining the precombustion chamber with the inner surface of the cylinder head;
• a pilot fuel injector means and an igniter means both located in the precombustion chamber which inject and ignite a precharge;
• a main fuel injector means in the cylinder head;
• a bowl shaped recess comprising the main combustion chamber non-concentrically located in the top surface of the piston in close proximity with the main injector means in the top dead center position;
• a first ramp means located in the top surface of the piston tangentially joining the main combustion chamber recess and substantially aligned with the said lineal passage, when the piston is approximately at the top dead center position, whereby the burning gases exiting the precombustion chamber are directed into the main combustion recess;
• and
• a second ramp means in the top surface of the piston laterally joining the first ramp means whereby the compressed gases, between the cylinder head and piston top surface as the piston approaches the top dead center position, flow down the second ramp means mixing with the burning gases flowing across the first ramp means causing ignition in the main combustion chamber.
