Abstract:
An auxiliary injector arrangement in a fuel supply system for an internal combustion engine. The auxiliary injector arrangement includes at least one injector mounted in the inlet manifold upstream or downstream of the throttle and adapted to supply fuel at times when the main fuel supply system cannot supply sufficient fuel. The main fuel supply system and the auxiliary injector may be operated on LPG, natural gas or petrol. The auxiliary injector may be a liquid fuel injector or gaseous fuel injector.
Abstract:
A high pressure fuel system includes a combination bypass and safety pressure release valve across the high pressure fuel pump. The combination valve allows the feed pump to directly provide fuel to the system before the high pressure pump reaches full output pressure. The valve also releases overpressure in the system when the high pressure pump is deadheaded. The combination valve includes a check ball which allows fuel to flow from its input to its output when the pressure is greater at its input than at its output.
Abstract:
An internal combustion engine having a pollution control system with a catalytic converter using a two-phase fuel system in which a small supply of flammable gaseous fuel is used for ignition and initial start-up of the engine. As the engine is warmed up and the catalytic converter is heated, the gaseous fuel is phased out and the liquid fuel is phased in.
Abstract:
The invention pertains to a fuel injection device operating according to the solidstate energy storage principle, whereby a rotor element carried in a pump housing of an electromagnetically driven reciprocating pump is accelerated almost without resistance, whereby the rotor element stores kinetic energy and impacts on a piston element, so that a pressure impulse is generated in the fuel contained in a closed pressure chamber before the piston element due to the fact that the stored kinetic energy of the rotor element is transferred via the piston element to the fuel in the pressure chamber and whereby the pressure impulse is used for the injection of fuel through a nozzle and whereby the rotor element is carried form-locking on the piston element and the two elements are mutually spring-mounted.
Abstract:
The invention pertains to a fuel injection device operating according to the solid state energy storage principle, whereby a piston element mounted in a pump cylinder of an electromagnetic reciprocating pump, displaces quantities of the fuel to be injected during a virtually resistanceless acceleration phase during which the piston element stores kinetic energy, before the ejection in the pump area. The displacement is stopped suddenly with the means for interrupting the displacement, so that a pressure impulse is generated in the fuel contained in a closed pressure chamber by direct transfer of the stored kinetic energy of the piston element to the fuel in the pressure chamber. The pressure impulse for the ejection of fuel is used by an injection device, whereby the means for interrupting the displacement and producing the pressure impulse are arranged outside the leading liquid-tight contact area between piston element and piston cylinder of the reciprocating pump.
Abstract:
A motorcycle powered by a two cycle crankcase compression fuel injected internal combustion engine. The injection system for the engine includes a main fuel air/injector that injects fuel directly into the combustion chamber and a second or auxiliary fuel injector that injects fuel into the induction system for the engine. Control means control the fuel injectors so that the second or auxiliary fuel injector supplies fuel only during starting and high load, high speed conditions. The engine components are laid out in such a way that the spark plugs of the engine and the fuel injector will each be exposed to unobstructed air flow for cooling.
