| Number | Title | Issue Date |
| 7311094 | Method for operating an internal combustion engine Operation of an internal combustion engine with oil lubrication and electronic fuel injection, includes the steps of determining a flow of fuel mass (mkp_ausg) evaporating out of oil, and determining a setpoint injected-fuel quantity (rk_ev) with taking into account... | 12/25/2007 |
| 7117857 | Fuel supply system for outboard motor An outboard motor fuel vapor separator-venting system that vents fuel vapor from a fuel vapor separator through a vapor relief valve. The vapor relief valve allows vapor to gradually be delivered from the vapor separator to an air induction system depending on the a... | 10/10/2006 |
| 7114491 | Fuel supply apparatus and vapor separator in outboard engine With a low-pressure pump, fuel is supplied to a vapor separator comprising an air discharge port and a ball valve for closing the air discharge port in association with a rise in fluid level of the fuel supplied to the vapor separator. When the fuel is filled into t... | 10/03/2006 |
| 7028672 | Fuel supply system for an internal combustion engine In a fuel supply system for an internal combustion engine having two separate storage containers for liquid fuels, both connected to a first controllable valve which is connected, via a connecting line including a fuel pump to an inlet of a second controllable valve... | 04/18/2006 |

The pumped ... | 09/17/1996 |
| 4864996 | Fuel injected two cycle engine with progressive throttle linkage for improved resolution of throttle position sensor A two cycle crankcase compression fuel injected internal combustion engine has a first set of one or more throttle valves (104, 106) controlling combustion air flowing into the crankcase, and a second set of one or more throttle valves (110, 112) also con... | 09/12/1989 |
| 4836152 | Exhaust heated crankcase for 2-cycle marine engine The idle exhaust pressure relief system in an outboard motor is utilized to simultaneously heat the engine crankcase or other parts of the fuel supply system to prevent the puddling of fuel typically occurring at lower engine temperatures. Because the idl... | 06/06/1989 |
| 4813395 | Two-cycle engine and method of operation A method and system, including a valve (32) for controlling the amount of fluid purged from a cylinder (12) of a two-cycle engine prior to the combustion of an air-fuel mixture within the cylinder especially during low demand periods of engine operation. ... | 03/21/1989 |
| 4794889 | Fuel puddle bleed shut-off for fuel injected two cycle engine A marine fuel injection system for a two cycle crankcase compression internal combustion engine includes a puddled fuel return line (44) between the crankcase (16) and a vapor separator (33). A shut-off valve (50) in the puddled fuel return line (44) is c... | 01/03/1989 |
| 4794888 | Fuel puddle suction system for fuel injected engine A marine fuel injection system for a two cycle crankcase compression internal combustion engine includes a puddled fuel return line (44) having an outlet (44b) in the excess fuel return line (43) from the fuel injector (24) and pressure regulator (26) to ... | 01/03/1989 |
| 4770132 | Draining system for outboard engine An outboard motor powered by a two-cycle crankcase compression internal combustion engine. A system is incorporated for draining condensed fuel from a plurality of locations in the engine induction system through a common conduit to a combustion chamber f... | 09/13/1988 |
