摘要： An internal combustion engine having an engine housing containing an oil sump in communication with an oil fill conduit, and a fuel pump including a pump assembly having at least a portion thereof formed integrally with the oil fill conduit and in fluid communication therewith. The fuel pump is actuated by pressure pulses created within the engine crankcase when the engine is running, which are communicated to the fuel pump through the oil fill conduit.

摘要： A diaphragm carburetor for an internal combustion engine is provided, and has a housing with an impulse pressure driven fuel pump. Provided in the housing is a chamber that is divided by a diaphragm into a pump chamber and a drive chamber that is acted upon by impulse pressure fluctuations during operation of the internal combustion engine. In order with the least available impulse pressure differences of the engine to effectively deflect the diaphragm in the chamber, the freely movable diaphragm surface of the diaphragm is maximized and the conveying stroke of the diaphragm is enhanced by a spring. The movable diaphragm surface assumes a major portion of the surface of the plane of separation in which the diaphragm is disposed. For this purpose, a fuel intake valve and a fuel outlet valve are spaced from the diaphragm, and in particular are removed from the plane of separation in which the diaphragm comes to rest.

摘要： The invention is directed to a fuel-injection arrangement for a two-stroke engine in a motor-driven chain saw. An injection pump is mounted in a base housing with the injection pump including a pump piston axially displaceable in a pump cylinder. The pump piston delimits a pump chamber. The pump chamber is connected via a suction valve to a fuel tank. The fuel drawn by suction is pumped by the pump piston via a pressure valve, an injection line and an injection valve to the engine. For driving the pump piston, the latter is connected at one end to a membrane via a membrane plate. The membrane delimits a work chamber charged with fluctuating crankcase pressure. A simple assembly is provided by arranging the pump chamber, the suction valve and the pressure valve in a common valve housing which, in turn, is seated in the base housing of the injection pump in a seal-tight manner. The injection line is connected directly to the valve housing. This permits a preassembly of the valve housing with the valves provided therein which facilitates the manufacture of the fuel-injection arrangement.

摘要： A fuel control system for low pressure fuel injection apparatus on an internal combustion engine. An impulse fuel pump operated by pulsating crankcase pressure delivers a desired quantity of fuel to the fuel port of the engine combustion chamber, and returns the unused portion of its output to the fuel tank through a bypass line. The quantity of fuel diverted to the bypass is controlled by a pressure actuated valve as a function of crankcase pressure, which is determined by throttle demand and engine speed, and by the pump output, as measured by pressure in the fuel line.
