摘要： An internal combustion engine includes an engine housing that defines a main combustion chamber separated from a precombustion chamber by a flame communication passage way. A source of gaseous fuel is fluidly connected to one end of a fuel supply passage. A check valve, which includes a valve body with a valve seat, and a valve member, is positioned between the other end of the fuel supply passage and the precombustion chamber. The valve member is moveable between an open position and a closed position. The valve body and the valve member define a fluid passage that fluidly connects the fuel supply passage to the precombustion chamber when the valve member is in its open position. The valve body and the valve member substantially fluidly isolate the valve seat from the precombustion chamber when the valve member is in its closed position.

摘要： A diesel cycle, direct injected internal combustion engine is provided with a piston recess or bowl into which fuel is injected each combustion cycle. One or more reaction chambers adjacent the piston recess are in communication with the recess through an array of discrete orifices located along the side wall of the recess. Partial reaction of fuel and air in the reaction chambers each combustion cycle produces radicals including intermediate species for seeding a fuel air mixture of a following combustion cycle through a delayed discharge of radicals from the reaction chamber into the piston recess. The discrete orifices are arranged in a specific array that ensures a desired chaotic flow in the reaction chambers and maximum interaction between radicals discharged from the reaction chamber and the soot cloud formed in the combustion chamber upon ignition of the fuel air mixture in the piston recess. Two or more rows of orifices may be used with at least one row located centrally along the reaction chamber cross-section and at least a second row intersecting the first row and arranged diagonally or vertically relative to the first row. The diagonal or vertical row includes orifices that intersect the reaction chamber tangentially at upper and lower regions thereof. The disclosed apparatus results in an exhaust effluent having markedly reduced smoke and particulate components.

摘要： An internal combustion engine includes a compression chamber that is delimited by fixed housing walls and a movable piston mounted therein, and a porous component that fills the combustion chamber, which is separate from the compression chamber. The combustion of fuel and air takes place exclusively within the porous component. The compression chamber is connected to the combustion chamber only via an overflow cross-section designed to allow the transfer of combustion gases created during combustion from the combustion chamber into the compression chamber.

摘要： A reciprocating machine includes a housing (12) and piston means (20) that are cyclically relatively displaceable along an axis (11) to define a variable volume working chamber (50). There is further provided air inlet means and fuel inlet means (100) admitting air and fuel to the working chamber for forming an ignitable mixture after compression of the air therein, and means to exhaust combustion products from the working chamber. The variable volume working chamber (50) includes at least two sub-chambers, a combustion chamber (54) and a main chamber (52) mutually displaced on the axis (11) and in communication at a cross section (53) at which gas in the combustion chamber (54) may expand at least partially laterally as it flows from the combustion chamber (54) into the main chamber (52). The air admission means, the exhaust means and the chambers (52, 54) are arranged so that a swirl of gas is generated and maintained about the axis (11) in both chambers (52, 54) during operation of the machine.

摘要： An apparatus and method for the creation, placement and control of an area of electrical ionization within an internal combustion engine combustion chamber. This area of electrical ionization is positioned so that all of the fuel being injected into the combustion chamber must pass next to or through the area of electrical ionization to ensure that combustion has been initiated for all of the fuel as it is injected. This area of electrical ionization can be kept on as long as it is necessary to insure that the all of the fuel that is injected into the combustion chamber can be completely combusted. An engine equipped with this electrical ionization device has its fuel economy enhanced by timely, controlled, and complete combustion of all of the fuel injected into its combustion chamber. Furthermore, the pollutant emissions of both oxides of nitrogen and unburned hydrocarbons are reduced dramatically. Further, cold starting capability of this engine is greatly enhanced by a major reduction in the time necessary for the engine to warm up and a major reduction of pollutants created by the engine during the warm-up period. Additionally, this method of combustion also allows the engine to operate at a higher speed (rpm) allowing an increase in peak power output.
摘要翻译：一种用于在内燃机燃烧室内创建，放置和控制电离电离区域的装置和方法。这种电离电场被定位成使得被注入到燃烧室中的所有燃料必须通过电离离子区域或通过电离区域，以确保在所有燃料注入时已经开始燃烧。只要有必要确保注入到燃烧室中的所有燃料能够完全燃烧，就可以保持该电离区域。装备有这种电离离子装置的发动机通过对喷射到其燃烧室中的所有燃料进行及时，受控和完全的燃烧来提高其燃料经济性。此外，氮和未燃碳氢化合物的污染物排放显着减少。此外，发动机预热所需的时间大大减少，并且在预热期间主要减少发动机产生的污染物，大大提高了该发动机的冷启动能力。此外，这种燃烧方法还允许发动机以更高的速度（rpm）运行，允许增加峰值功率输出。

摘要： The present invention relates to a working cycle for a heat engine, especially of the reciprocating piston type, having a gas as working medium, including the steps of isentropic compression of the gas, isochoric addition of heat to the gas, isentropic expansion of the gas, and isochoric return of the gas to its initial condition. The invention is characterized in that the gas, before or during the compression, is divided into two portions, that the gas portions are compressed to different degrees, that heat is added only or mainly to the gas portion compressed to the lowest degree, and that the two gas portions are brought into connection with each other and are expanded together.

摘要： An internal combustion engine comprises an engine housing which defines a main combustion chamber that is separated from a precombustion chamber by a flame communication passageway. The engine housing further defines a fuel supply passage with one end and an opposite end. A source of fuel is fluidly connected to the opposite end of the fuel supply passage. A check valve which includes a valve body with a valve seat and a valve member is positioned between the one end of the fuel supply passage and the precombustion chamber. The valve member is movable between an open position and a closed position. The valve body and the valve member define a relatively wide fluid passage that fluidly connects the fuel supply passage to the precombustion chamber when the valve member is in the open position. The valve body and the valve member define a relatively narrow stagnation region separating the valve seat from the precombustion chamber when the valve member is in the closed position.

摘要： A torch jet spark plug (10) for use in a spark ignition system of an internal combustion engine. The spark plug (10) of this invention provides for ignition of an air/fuel mixture within a combustion prechamber (12) within the plug (10), which creates a jet of burning gases that are propelled through an orifice (32) into the engine main combustion chamber to increase the burning rate of the air/fuel mixture within the combustion chamber. The orifice (32) is oriented in the plug (10) so that its axis is not parallel with the longitudinal axis of the plug (10), enabling the jet of burning gases to be selectively directed to any desired region within the combustion chamber, such as a region within the chamber that would not otherwise burn well compared to other regions of the chamber.
