摘要： An internal combustion engine is designed to improve burning of the fuel therefor for reducing the harmful emissions in the exhaust gases thereof. An auxiliary combustion chamber is provided in the cylinder head being arranged to open toward the center of the cylinder through an orifice. A lean mixture fuel is introduced into a main combustion chamber formed by the cylinder walls, the cylinder head and the forward face of a piston reciprocable therein through a suction port curved for causing the lean mixture to swirl in one direction about the outer part of the main combustion chamber, and a rich mixture is introduced just in advance of a suction valve in said suction port which opens and closes communication between the suction port and the main combustion chamber upon actuation in a manner to swirl in a direction opposite to the lean mixture and near the center of the main combustion chamber. In compression, the rich mixture is thus drawn into the auxiliary combustion chamber where a spark plug ignites the same and fires the lean mixture in the main chamber by a flame jet of combustion passing through the orifice.

摘要： A pre-chamber system for an internal combustion engine has a pre-chamber having a wall, a spark plug having at least one electrode, and a gas introduction device, particularly a gas valve. A gas channel connects the gas introduction device to the pre-chamber via an inlet opening. A riser channel connects the pre-chamber (2) to a combustion chamber of the internal combustion engine. A guiding device influences the flow of the gas in the pre-chamber, the guiding device being arranged adjacent to the inlet opening in such a manner that in operation, the volume flow of hot gas flowing into the pre-chamber via the channel (8) and reaching the electrode (13) of the spark plug (4) is reduced by the guiding device (9).

摘要： An air/fuel mixture is ignited in an internal combustion engine by receiving the air/fuel mixture as an incoming air/fuel mixture flow from a main combustion chamber of the internal combustion engine into an enclosure adjacent the main combustion chamber. The enclosure defines a first chamber enclosing first and second ignition bodies and the enclosure defines a second chamber adjacent the first chamber and connected to the first chamber via a passage. A portion of the air/fuel mixture received in the enclosure is directed toward an ignition gap between the first and second ignition bodies and another portion is directed into the second chamber. The air/fuel mixture is then ignited in the ignition gap, and flame from combustion in the first chamber is ejected into the main combustion chamber. Then, flame from combustion in the second chamber is ejected into the main combustion chamber.
