  • Fuel delivery system
    Patent number: 7222613
    Abstract: A fuel delivery system for an engine is disclosed which includes an injector (20) and a housing (3) for supporting a fuel injector (20). A regulator (202, 313) is provided for regulating the pressure of fluid in the housing to maintain the pressure at about supply pressure, and the pressure downstream of the regulator at a low pressure so that fuel which passes the regulator is able to evaporate. The evaporated fuel is supplied to a heater (250) to heat the fuel, and the vapour is supplied to a vapour injector (260) for injection into the engine. The passage of the liquid petroleum gas fuel through the housing (3) cools the injector (20) to maintain the fuel in a liquid state, and therefore prevent boiling of the vapour within the injector.

  • Engine cooling system configuration, and personal watercraft incorporating same
    Patent number: 7219644
    Abstract: An internal combustion engine for a personal watercraft in which cooling water in an oil cooler housing is naturally discharged when the personal watercraft is pulled up on land. An oil cooler is disposed within an oil cooler housing on an upper front side of the engine. The oil cooler housing enables cooling water taken from the cooling water intake port at the positive pressure side of the jet propulsion pump to flow about the oil cooler thereby cooling lubricating oil. A water pipe connects the pump to a cooling water inflow opening at a lower end of the oil cooler housing. Cooling water discharged from an upper end of the cooler housing is directed to the engine. The oil cooler housing resides above the water pipe and the crankshaft of the engine, and the pump intake lies below the crankshaft permitting free discharge of cooling water therefrom.

  • Internal combustion engine having an improved oil cooling structure, and personal watercraft incorporating same
    Patent number: 7219643
    Abstract: The use of an oil cooler in an internal combustion engine for a personal watercraft is controlled, whereby excessive cooling of the engine during warmup with cold water operation is avoided, and dilution of oil is substantially prevented. The internal combustion engine includes a bypass oil path connecting respective oil paths upstream and downstream of the oil cooler. The bypass oil path permits oil to be selectively detoured around the oil cooler. An oil thermostat is provided in the upstream oil path for selectively opening either a path to the oil cooler or the bypass oil path, and the oil thermostat is operable to switch the flow of oil therebetween. The oil thermostat opens the bypass oil path when the temperature of the oil is below a predetermined temperature, and directs oil to the oil cooler when the temperature of the oil is equal to or exceeds a predetermined temperature.
