    摘要： Ein Verbrennungsmotor (12) besitzt ein Kraftstoffsystem, das ein Kraftstoffventil (26) umfasst. Das Kraftstoffventil (26) besitzt ein Gehäuse (67), in dem ein Kraftstoffraum (62) ausgebildet ist. Das Kraftstoffsystem besitzt eine Kraftstoffpumpe (34), die Kraftstoff aus einem Kraftstofftank (32) in den Kraftstoffraum (62) fördert. Das Kraftstoffsystem besitzt außerdem eine Förderpumpe (59, 69, 79, 89) zum zwangsweisen Fördern von Kraftstoff in das Kraftstoffsystem. Ein zuverlässiges Spülen des Kraftstoffsystems und eine gute Kühlung des Kraftstoffventils (26) können erreicht werden, wenn sich die Förderpumpe (59, 69, 79, 89) in einer Zuleitung (50, 72) zum Kraftstoffraum (62) des Kraftstoffventils (26) befindet und Kraftstoff in den Kraftstoffraum (62) fördert, und wenn der Kraftstoffraum (62) mit einer Entlastungsleitung (58) verbunden ist, in der ein erstes Ventil (60, 73) angeordnet ist.

    摘要： A method for controlling a valve of a crank case scavenged internal combustion engine includes determining a valve control sequence, wherein the valve is controlled in consecutive periods of revolutions each having a period length of at least ten revolutions, and controlling the valve according to the valve control sequence to adjust the ratio of fuel to air in a combustible mixture delivered to an engine combustion chamber. Determining the valve control sequence for each period includes providing a number of valve shut-off positions, wherein the number of valve shut-off positions corresponds to an amount of fuel or air to be supplied to the engine during the corresponding period, and determining which revolutions of the period that the valve is to be closed.

    摘要： A fuel injection system for a two-stroke small engine (16) has a charge forming device (14) with an injector mixing passage (62) which forms a rich fuel and air mixture supplied to a tuned injector tube (12) connected adjacent one end through a port to the engine cylinder and adjacent the other end to the engine crankcase. The charge forming device (14) has a high speed fuel circuit which supplies at least a majority of the fuel to the mixing passage under wide open throttle operating conditions and preferably a minor portion of the fuel is also supplied by an idle fuel circuit which under engine idle conditions preferably supplies essentially all of the fuel to the engine. A separate inlet air flow passage of the charge forming device also supplies primarily air to the crankcase of the engine for transfer to the cylinder. Under engine wide open throttle conditions, preferably a very minor quantity of fuel with oil therein is supplied through the inlet air flow passage to the crankcase and transferred to the cylinder to provide lubrication of the moving parts in the crankcase and some cooling of the engine.

    摘要： A two-stroke internal combustion engine having a compressed air assisted fuel injection system (22). The injection system (22) has an accumulator (34) that uses scavenged air from the crankcase (18) as the compressed air source. The injection system (22) has a valve (42) connected to an exit from the accumulator (34). The valve (42) is connected to a diaphragm (44) with two diaphragm pressure chambers (48,50) on opposite sides of the diaphragm (44). Both diaphragm pressure chambers (48,50) are connected to pressure in the crankcase (18); one of the diaphragm pressure chambers (48,50) by a flow restrictor (56).
