摘要： A prechamber device includes an enclosure body (104) and a cap (108) forming an enclosed volume (112). The enclosure body has an orifice (128) at one end. A precombustion chamber (116) is defined within the enclosed volume and is in fluid communication with the orifice. A valve plug (136) is movable along an axial axis of the enclosure body to adjust a valve opening at the orifice to a range of positions from a fully open position to a closed position. An actuator (164) is coupled to the cap and the valve plug and is controllable to displace the valve plug along the axial axis of the enclosure body. The prechamber device is operable to generate turbulent jets that are directed into a main combustion chamber of an engine cylinder through the valve opening. During an engine cycle, the valve opening is controlled between the range of positions based on detected engine speed and engine load.

摘要： The inventive operating method for an internal combustion engine involves a stroke for injecting components of the air-fuel mixture in a main combustion chamber and an ignition chamber, a stroke for compressing said air-fuel mixture simultaneously in the main combustion chamber and the ignition chamber, the isolation of the main combustion chamber from the ignition chamber by closing a connecting hole with the aid of the flat gate and subsequent ignition of the air-fuel mixture in the combustion chamber at the end of the ignition stroke. The fuel being fully burned in the ignition chamber, a high-temperature gas jet is introduced into the main combustion chamber at a constant volume by deplacing the flat gate into the cavity of the main combustion chamber in a parallel position to itself and along the axis of the connecting hole at a distance equal to 0.9-1.5 of the radial dimension thereof during the time period which is equal to or less than 0.1 sec. The quantity of the fuel injected into the ignition chamber is selected according to a condition that the pressure of high-temperature products in the ignition chamber is five times higher than the pressure of the air-fuel mixture in the main combustion chamber at the instant corresponding to the introduction of the gasflow therein. Afterwards, expansion and exhaust strokes are carried out.

摘要： An internal combustion engine has a main combustion chamber (20) in communication with a preliminary combustion chamber (30) and has an isolating valve (32) for isolating the preliminary from the main chamber. During a compression stroke valve (32) closes isolating a charge of fuel-air mixture in the preliminary combustion chamber (30) while another charge of fuel-air mixture in main chamber (20) undergoes further compression. The fuel mixture in the preliminary combustion chamber (30) is ignited or self ignites and isolating valve (32) then opens permitting the ignited fuel in turn to ignite the charge in main chamber (20) for the power stroke. The fuel in the main chamber may be of a different kind from the fuel in the preliminary chamber and/or may be in a different proportion to air in the mixture and for preference a fuel-air mixture and compression combination in the first chamber are optimized for ignition while another fuel-air mixture and compression in the main chamber are separately optimized for overall engine efficiency.
