摘要： A pulse fuel injector for a two-stroke internal combustion engine which utilizes a throttle body with a fuel venturi and a throttle valve in the body. A one-way pulse passage connects the crankcase of the engine and the venturi to direct air pulses to the venturi to aspirate fuel into the throttle body where it is drawn into the crankcase for transfer to the firing chamber of the engine.

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： Two-stroke, fuel injected internal combustion engines for unmanned aircraft and associated systems and methods are disclosed herein. Engines configured in accordance with embodiments of the disclosure can include, for example, (a) an electronic fuel injection system configured to provide a desired low fuel rate by injecting fuel every nth compression cycle rather than every cycle (so-called "skip-cycle" operation), (b) one or more pressure sensors configured to measure fluctuations in peak crankcase pressure and use such fluctuations to control fuel injection delivery, and (c) a multi-cylinder configuration having a common crankcase with a fuel injection arrangement configured to mitigate or eliminate problems with mixed redistribution.

摘要： A uniflow scavenging two-cycle engine includes: a cylinder in which a combustion chamber is formed; a piston that slides in the cylinder; a scavenging port that is provided one end side of the piston in a stroke direction in the cylinder and suctions active gas in the combustion chamber in response to a sliding motion of the piston; and a fuel injecting unit (126) that is provided on an outer side of the cylinder in a radial direction from the scavenging port and injects fuel gas into the active gas which is suctioned into the scavenging port. The fuel injecting unit includes an inner pipe (156) which has an inner hole penetrating between an inside and an outside thereof and through which fuel gas is guided to the inside, an outer pipe (158) which has an outer hole penetrating between an inside and an outside thereof and stows the inner pipe in the inside thereof so as to form a double pipe with the inner pipe, and a driving unit (154) which changes relative positions of the inner pipe and the outer pipe and changes an opening amount as an area of an overlap between the inner hole and the outer hole.

摘要： In an opposed-piston engine, two or more fuel injectors are mounted to a cylinder for direct side injection into the cylinder. The injectors are controlled so as to inject either a single fuel pulse or a plurality of fuel pulses per cycle of engine operation in order to initiate combustion during varying engine speeds and operating conditions.

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).
