摘要： Exhaust pressure of an air-cooled miniature internal combustion engine is used for fuel metering and fuel delivery to the engine under higher pressure than previously obtainable from muffler back-pressure in the prior art even though the back-pressure in the exhaust system is kept to near zero for maximum engine power and cooling. This is accomplished by tapping on to the engine's exhaust stream right at and facing the exhaust port. As the engine unloads, the muffler's exhaust is further aspirated outward by a faster-moving cooling airstream hence a further reduction muffler's back-pressure causing a decrease in fuel pressurization thus a decrease in fuel flow to the engine in corresponding with a known decrease in fuel requirement at high speed as it unloads, and vice-versa. Special fuel tanks designs for this fuel system are disclosed, as well as additional means for further boosting fuel pressure.

摘要： A fuel supply and glow plug arrangement for a portable electrical power supply fueled by a gaseous fuel internal combustion engine. The gaseous fuel flow to the engine is controlled by a solenoid valve having its duty cycle varied to vary engine speed. In addition, the solenoid valve is shut off when the engine speed falls below a predetermined speed so as to prevent fuel leakage. The engine is fired by a flow plug which is supplied with power at a high power level during cranking and at a lower power level during running.

摘要： In a muffler for a two-cycle combustion engine of the type commonly used to power miniature aircraft, cars, boats and models, the exhaust gas is directed into an expansion chamber for expansion and cooling, thence through a series of spaced baffles in a baffle chamber, and thence through a nozzle to the atmosphere. The baffle plates may comprise one or more different types having different sonic wave reflective characteristics and different impedances to gas flow. The baffle plates are spaced apart by one or more of a number of spacers providing different axial spacing between the baffle plates. THe baffle plates and their spacings are chosen by the user so as to obtain the required degree of muffling with the least amount of back pressure on the engine, as back pressure reduces engine power. The user is supplied with a kit having the various different type baffles and spacers. The user selects from the kit the desired spacers and baffles in accordance with his own experiments or in accordance with experimental data supplied by the manufacture of the kit. The nozzle includes a threaded end for mating with the threaded interior of the baffle chamber so that by removing the nozzle the baffles and the spacers may be stacked in the baffle chamber in the desired configuration and the nozzle replaced for securely holding the baffles in the desired geometry.

摘要： A carburetor and carburetor fuel metering valve for an internal combustion engine. The metering valve has slidably interfitting valve sleeves which are relatively rotatable by adjustment of the carburetor throttle valve and contain fuel metering ports whose overlap defines a fuel metering orifice having an area which is progressively varied by such relative rotation to meter fuel to the engine in relation to air flow. The metering valve includes at least two sets of fuel metering ports which may be selectively disposed in fuel metering relation to provide a mid-range fuel adjustment independent of throttle setting. The metering valve may also include an idling fuel adjustment for adjusting the effective orifice area of each metering port set and thereby fuel flow in the idling setting of the throttle valve and a high speed fuel adjustment for adjusting fuel flow in the high or full speed setting of the throttle valve.
