Abstract: A method is for starting a combustion engine having a pull-rope starter. A fuel/air mixture is fed to the engine via an intake channel. The mixture is ignited by a spark plug. The combustion drives the piston downward and drives a crankshaft rotationally. The fuel system has a fuel channel opening into the intake channel. An electric fuel valve is open in its currentless state and closes a fuel channel only when an operating voltage is applied. An electronic control unit actuates the fuel valve and triggers an ignition spark and is utilized by a generator to supply energy to the control unit, the fuel valve and the ignition device. To prevent excessive enriching of the fuel/air mixture during starting, the energy, which is generated at the beginning of the rotation of the crankshaft, is used to first close the fuel valve before the control unit triggers an ignition spark.

Abstract: An internal combustion engine having an intake channel that opens into a crankcase. A first fuel channel opens into the intake channel to supply fuel thereto as a function of underpressure in the intake channel. An auxiliary channel opens into a transfer channel that fluidically connects a crankcase to the combustion chamber. A second fuel channel opens into the auxiliary channel and is connected to a storage reservoir for fuel. At least one valve controls the quantity of fuel to be supplied to the engine via the auxiliary channel. Largely fuel-free air is supplied to the engine via the intake channel during idling. During a first revolution of the crankshaft, fuel is supplied via the auxiliary channel, so that a combustible mixture can form in the combustion chamber. During a second revolution, largely fuel-free air is supplied via the auxiliary channel and the combustion chamber is scavenged with largely fuel-free air.

Abstract: A valve assembly is provided for replacing the idle mixture jet screw of a conventional carburetor and includes structure for aerating the liquid fuel metered by the valve assembly, adjustably metering the aerated fuel supplied to the associated carburetor idle fuel port during idle operation mode of an associated combustion engine, increasing the flow of aerated fuel through the idle fuel port responsive to increase of engine speed while the associated throttle valve is open and at the same time effectively decreasing venturi vacuum of the associated carburetor and thus reducing carburetor main jet fuel flow, and reducing flow of fuel through the idle fuel port below idle mode fuel flow when the engine is operating under an engine braking mode, and reducing fuel flow during cruising operation mode; and also in the said three operating modes reducing the CO (carbon monoxide) in the residual of combustion; this as a result of a most complete combustion.

Abstract: This invention relates to a process and a jet to produce an idling vaporized mixture in an internal combustion engine. The process consists in vaporizing the mixture in two phases: one premixing phase in a turbulence chamber (10) consisting of mixing the fuel flow C.sub.r with an auxiliary air flow A.sub.a, which is in a lower proportion to the idling air flow A.sub.r, to obtain a highly vaporized premixture, and a final mixing phase made in a second chamber, known as the mixing chamber (5) and consisting of mixing the premixture M.sub.p with the slow-running air flow A.sub.r. A needle is responsive to changes in the vacuum level and enables the flow rate of the fuel to be adjusted as a function of the engine speed.

Abstract: Gasoline engine induction system for automobiles and the like provides less emission of undesirable exhaust products by having carburetor without an idle jet so that engine idles on a lean main jet with small enrichment arranged for idle as against offidle operation. Enrichment can be provided as by having the closing of the throttle open an external vent in the carburetor bowl, or by having a supplemental fuel jet opening in throttle barrel alongside idle position of downstream tip of throttle blade. Automatic choke can also be operated by mixture taken from downstream of carburetor venturi, heated, and delivered to thermally responsive choke actuator. Above features can be incorporated in a single small primary carburetor that is combined with one or two large secondary carburetors used for high power operation. Supplemental heating can be provided for mixture delivered by primary carburetor.
