PURPOSE:To enhance the fuel consuming, starting and exhaust gas characteristics of an engine by allowing the fuel to be supplied to the engine to run against a high-speed jet stream sent from a pressure source so as to pulverize the fuel, and thereby carryint out pulverization of fuel with good performance. CONSTITUTION:Mixture gas, which has intruded through a mixture gas takeout hole 16 of a rotary piston engine, jets out from a nozzle 10 at a high speed. Neg. pressure generated in a minor venturi 3 is introduced to a fuel injection chamber 4, which is given a sufficient large size compared with the diameter of the outlet 9, where the pressure is always equal to the pressure at the minor venturi 3, being free of influence of the intense neg. pressure acted on the outlet 9. The fuel gauged at the main fuel system provided with a main fuel jet 6 shall jet out of a jet part 8 into the fuel injection chamber 4. Thus the neg. pessure corresponding to the rate of flow of the suction gas flowing through the venturi part is generated in the fuel injection chamber 4, and simultaneously fuel jets out of the jet part 8 in such a manner as matching with the former described action. The fuels run against the high-speed jet stream to provide well pulverized particles of fuel. |
