Um bei einem Membranvergaser, dessen membrangesteuerte Regelkammer (15) für Kraftstoff (K) über eine Anzahl von Kraftstoffkanälen (10,16,18,21) mit einem Ansaugkanal (1) für Luft (L) verbunden ist, bei gleichzeitig hohem Wirkungsgrad eine möglichst geringe Beschleunigungsverzögerung zu erreichen, sind erfindugsgemäß alle Kraftstoffkanäle (10,16,18,21) über deren gesamte Länge voneinander getrennt geführt. Dadurch werden sowohl ein Hauptkanal (10) als auch ein Leerlaufkanal (21) und jeder Teillastkanal (16,18) aus der Regelkammer (15) unabhängig voneinander mit Kraftstoff (K) gespeist. Da ein Eindringen von Luft (L) sowohl in den oder jeden Teillastkanal (16,18) als auch in den Leerlaufkanal (21) verhindert ist, bleibt jeder Kanal (16,18,21) während der gesamten Betriebsdauer vollständig mit Kraftstoff (K) gefüllt, so daß dieser bei plötzlichen Beschleunigungsvorgängen ohne Verzögerung in den Ansaugkanal (1) des Membranvergasers austreten kann. |

A stratified scavenging two-cycle engine, in which control of an air flow rate provides a favorable accelerating performance and can prevent deterioration of exhaust gas. The stratified scavenging two-cycle engine comprises a scavenging flow passage (3) for connection between a cylinder chamber (4a) and a crank chamber (1a), an air flow passage (2) connected to the scavenging flow passage (3), air flow rate control means (12) for controlling a flow rate of air fed to the scavenging flow passage (3) from the air flow passage (2), and mixture flow rate control means (11) for controlling a flow rate of mixture sucked into the crank chamber (1a) from a mixture flow passage (10). The air flow rate control means (12) throttles an air flow rate at the time of acceleration. Alternatively, the air flow rate control means (12) is opened later than the mixture flow rate control means (11) at the time of acceleration. | ||||||

A two-stroke internal combustion engine having an air control arrangement which controls scavenging air flow during rapid engine acceleration to optimize the acceleration and maximum power output of the engine while maintaining low exhaust emissions from the engine. Desirably, the air control arrangement may comprise a valve that throttles the air passage to one half or less of its total flow area at a medium engine load or less and completely or fully opens at a medium engine load or more of the engine. Normally, the air control valve opens in unison with the throttle valve, but during rapid acceleration of the engine the air control valve opens later or more slowly than the throttle valve to control the supply of scavenging air to the combustion chamber of the engine thereby enhancing rapid acceleration of the engine. |

A carburetor for an internal combustion engine with an accelerator fuel pump in the carburetor having a piston actuated by a cam on a throttle valve shaft and a ball between them. The axis of a pump chamber in which the piston is slidably received is offset from and eccentric to the axis of rotation of the throttle shaft so that little fuel is supplied to the operating engine by the accelerator pump as the shaft is rotated to move the throttle valve from its idle position to an intermediate position and most of the fuel supplied by the accelerator pump to the engine is delivered as the shaft is rotated to move the throttle valve from the intermediate position to its wide open throttle position. This provides a proper fuel mixture to the engine to accelerate it and avoids the problem of supplying an overly rich fuel mixture to the engine during acceleration and particularly if the operator moves the throttle valve several times back and forth between the idle and intermediate positions before moving the throttle valve to the wide open position to accelerate the engine. |

Disclosed is an engine fuel supply apparatus which can be made smaller in size and in which the amount of fuel in an air-fuel mixture (13) can be increased with a fast response in correspondence with the operation of a throttle valve (23) when the engine (14) is accelerated rapidly. The fuel supply apparatus is provided with a fuel booster pump (16). A portion of an air-fuel mixture is introduced into a negative-pressure chamber (65) of the fuel booster pump via a negative-pressure chamber channel (38), and the fuel booster pump is actuated. The actuation forces air in a pump chamber (66) to flow into a pressure chamber (27), and fuel (12) in a fuel storage chamber (26) is temporarily supplied to a carburetor (11). |
