| Number | Title | Issue Date |
| 7021253 | Two-cycle engine A two-cycle engine is provided and includes a cylinder in which is formed a combustion chamber delimited by a reciprocating piston that via a connecting rod drives a crankshaft rotatably mounted in a crankcase that, in predetermined positions of the piston, communic... | 04/04/2006 |
| 6328004 | Internal combustion engines An internal combustion engine has a positive displacement supercharger which can be used with particular advantage in an underpumping two stroke engine which is in the form of a valved diaphragm which reciprocates in a housing to deliver positive pulses o... | 12/11/2001 |
| 6182449 | Charge air systems for two-cycle internal combustion engines A two-cycle internal combustion engine (10, 46, 66, 75, 86) has a motor-assisted turbocharger (13) where the motor (17, 56, 65, 77, 95) is activated by an external power source (18) to operate the turbocharger (13) to apply scavenging and charging air for... | 02/06/2001 |
| 5415078 | Reciprocating piston machine This invention relates to reciprocating piston machines which use the crankcase for pumping air or charge. The connecting rod with extension partitions the interior of the crankcase including the lower cylinder into two varying volumes during a portion of... | 05/16/1995 |
| 5163388 | Two-stroke I.C. engine with a super charger The invention relates to a more complex but considerably more emission-poor two-stroke engine than the conventional one. The HC-emissions become zero when completely burned. CO is controlled by the mixture ratio and NOx becomes very low owing t... | 11/17/1992 |
| 4712520 | Crank case compressor unit for a two cycle engine A means of continuously pressurizing an air/fuel mixture residing within a crankcase of a two cycle internal combustion engine is disclosed. The crankshaft fitted flywheel or counterweight of the engine is mounted with a plurality of vanes which extend fr... | 12/15/1987 |
| 4480597 | Two-stroke cycle gasoline engine A two-stroke cycle gasoline engine, comprising a power cylinder-piston assembly having a scavenging port configuration including a first scavenging port configuration first uncovered by the power piston as it moves along the power cylinder from its top de... | 11/06/1984 |
| 4445468 | 2-Stroke internal combustion engine and an ignition-combustion method of an internal combustion engine A 2-stroke engine having a combustion chamber and a scavenge port which is open to the combustion chamber. When the engine is operating under a light load in which a large amount of unburned components, incompletely burned components and oxygen remains in... | 05/01/1984 |
| 4430967 | Two cycle diesel engine The invention engine comprises a compressor with a rotary piston in a cylinder bore in a stator and a U-shaped box-like combustion-expansion compartment, conveniently called a U-box, immediately above and riding on the rotary piston, the U-box and the com... | 02/14/1984 |
| 4258669 | Two-stroke cycle gasoline engine A two-stroke cycle gasoline engine including at least one two-stroke cycle power cylinder - piston assembly incorporating uniflow scavenging and two horizontally opposed pistons, and a scavenging structure which gives zero or a relatively weak swirl to th... | 03/31/1981 |
| 4257365 | Two-stroke cycle diesel engine A two-stroke cycle diesel engine having at least one two-stroke cycle power cylinder-piston assembly incorporating uniflow scavenging and having two horizontally opposed pistons, at least first and second scavenging ports and two crankcases which may perf... | 03/24/1981 |
| 3931812 | Internal combustion engines A multi-cylinder 2-stroke fuel injection engine of the crankcase compression type has a separate crank chamber associated with each cylinder and inlet, transfer and exhaust ports in each cylinder. The exhaust ports of the engine communicate with an exhaus... | 01/13/1976 |
