| Number | Title | Issue Date |
| 7360511 | Opposed piston engine A two-cycle, opposed piston engine with side-mounted crankshafts and cylinders isolated from mechanical stresses of the engine includes tailored cooling of cylinders and symmetrical cooling of the interior surfaces of piston crowns. Each opposed piston includes a co... | 04/22/2008 |
| 7240647 | Piston engine A piston engine which has at least one dry-running piston-cylinder unit. It has a first housing (1), at least one cylinder arranged in or on the first housing (1) in which a piston is reciprocably arranged. The piston-cylinder unit further has a first ... | 07/10/2007 |
| 6904883 | Modular internal combustion engines A line of small internal combustion engines, including twin cylinder engines and single cylinder engines. The engines each include a crankcase, and one or more cylinder members attached to the crankcase, the cylinder members being separate components from the crankc... | 06/14/2005 |
| 6508223 | Four cycle outboard internal combustion engine for driving a watercraft A four cycle outboard internal combustion engine for driving a watercraft with a cylinder housing having cylinders arranged in at least two rows, wherein a piston is reciprocating in each cylinder, the pistons driving an approximately horizontally accommo... | 01/21/2003 |
| 5836273 | Reciprocating machine A reciprocating machine includes a cyclical kinematic chain in which power is transferred between translational and rotational motion. The kinematic chain includes a piston (2) reciprocating in a cylinder (1), connected by two connecting rods (9, 10) to d... | 11/17/1998 |
| 5383427 | Two-cycle, air-cooled uniflow gasoline engine for powering a portable tool A flexible line trimmer is powered by a two-stroke internal combustion engine. The engine is scavenged in a uniflow fashion and has a scavenging cylinder and an exhaust cylinder connected by a common combustion chamber. Each cylinder has a piston turning ... | 01/24/1995 |
| 4694785 | Piston apparatus A piston apparatus has a first pair of spaced-apart cylinders aligned along a cylinder axis. There is a pair of pistons, each piston being slidably received in one of the cylinders for reciprocation along the axis. A pair of spaced-apart crank members are... | 09/22/1987 |
| 4690113 | Internal combustion engine The invention relates to an engine including a cylinder defining a combustion chamber which receives a combustible mixture for the combustion thereof, a piston slidably mounted therein for reciprocation between a first limit position whereat the chamber d... | 09/01/1987 |
| 4658768 | Engine To reduce space requirements, vibrations and certain stresses in an engine, a different one of two pistons is mounted on each end of a single piston rod to which the crankshaft is attached by a cylindrical shaped connector that orbits around the crankpin ... | 04/21/1987 |
| 4614169 | Ultra high compression engine A reciprocating piston machine, such as an internal combustion engine, is provided with a piston translator arrangement operated by a pair of oppositely rotatable crankshaft means disposed on opposed sides of the cylinder longitudinal axis such that the p... | 09/30/1986 |
| 4543919 | Engine To reduce space requirements, vibrations and certain stresses in an engine, a different one of two pistons is mounted on each end of a single piston rod to which the crankshaft is attached by a cylindrical shaped connector that orbits around the crankpin ... | 10/01/1985 |
| 4419969 | Flexible cylinder-head internal combustion engine with cylinder compression adjustable for use with available fluid fuels In an internal combustion engine, two opposed pistons of equal radius are slidably mounted in a cylinder and respectively connected to cranks of unequal throws mounted for rotation at oppositely disposed cylinder ends in a common crankcase. The pistons ar... | 12/13/1983 |
