Abstract: An ignition device (22) is positioned in an ignition chamber (21) which in turn is positioned in a prechamber (11) in the cylinder head of an internal combustion engine. A valve controlling flow to and from the ignition chamber is opened to initiate ignition near top dead center of the compression stroke and is closed before the exhaust stroke to trap hot combustion gases in the ignition chamber. Very exacting control of ignition is achieved.

Abstract: This invention relates to a gas motor fuel delivery system having a gas mixer, which has a through passage having a gas mixing zone in which there is a suction dependent on the flow velocity prevailing there. The through passage of the gas mixer is part of a lean-gas line (2). Rich gas is delivered to the gas mixing zone of the gas mixer and admixed with the lean qas to raise the heating value of the latter to a value suitable for the motor.

Abstract: This invention relates to a gas engine, in particular a four-cycle gas engine, having a mixture line (7) to the combustion spaces in the cylinders (2) and having a mixer (5) in the mixture line (7), in which air is mixed into the fuel gas, and a metering valve (8) for the metering of the gas delivery, the metering valve (8) being actuated by a controller (4) for the control of the pollutant emission, and the controller (4) adjusting the metering valve (8) in dependence on the power setting of the gas engine (1) and an engine parameter measuring the pollutant emission.

Abstract: This invention relates to an exhaust gas measuring device, in particular for the measurement of the oxygen content in the exhaust gas stream of an internal combustion engine, which device can be connected to an exhaust gas line, having a measuring device arranged in an insulation, to which measuring device a measuring probe is connected, which is led out of the insulation.

Abstract: The invention relates to a combination power and heat unit with a bedplate (1), flanged-together machines (2, 3), a noise suppressor (8), an exhaust-gas heat exchanger (9), a cooling-water heat exchanger (19) as well as the associated auxiliary apparatus and piping, wherein the bedplate (1) shelters the noise suppressor (8) and the exhaust-gas heat exchanger (9) along its opposite longitudinal sides below the machines (2, 3), which are elastically supported on the bedplate (1).

Abstract: A power thermo-coupling unit with muffler (4, 5) and exhaust gas heat exchanger (6, 7) avoids the requirement of a disproportionately large space for component removal at the front end of the power thermo-coupling unit. The muffler (4, 5) and the exhaust gas heat exchanger (6, 7) each have two separate components, the lengths of which are shorter than the distances between the center column (8) and the end walls of the unit support (1).

Abstract: At least one inlet channel (4) for each cylinder is developed as a filler channel in which there is a flap valve (13) turning on an axis (12). During full load operation, the flap valve (13) is in a rest position, which does not influence the flow through the inlet channel (4). During partial load operation, however, the flap valve (13) is in a working position, in which it shapes the flow in the inlet channel so unsymmetrically that at the mouth (6) of the inlet channel (4) leading into the cylinder (1) the compressed air flowing out in large quantities has a tendency toward spiral and/or turbulence-reinforcing directions. In this way, fuel preparation is improved during the partial load operation of the motor, leading to combustion with low smoke and noxious substance levels and low consumption.

Abstract: A fuel injection system, especially for Diesel engines using relatively hard-to-ignite fuels. The system includes a low pressure pump for delivering an easily ignitable fuel into a pre-storage chamber within a pressure divider. A high-pressure pump delivers the main fuel component and also applies pressure to an expulsion piston which expels the prestored igniter fuel. A number of embodiments is presented.

Abstract: A safety arrangement for diesel engines to respond to an abnormal change of the ratio of the useful torque delivered by the diesel engine and the fuel quantity per power stroke. The latter is defined by the position of control rod of the injection pump. A transducer converts the control rod displacement into a mechanical or electrical control variable which is at least approximately proportional to the fuel quantity per power stroke. The control rod displacement is converted by a crank drive into a rotation of a correcting element, and the ratio of connecting rod length to crank radius is in the range between 6:1 and 8:1. The rotation angle of the correcting element is less than 90.degree. in the range between zero and full useful torque. The rotation angle range on either side of the crank position is 90.degree.. An electrical control variable may be generated by a transducer which is free of contacts and supplies a direct current signal proportional to the rotation angle of the correcting element.

Abstract: A compression-ignition internal combustion engine including a mixing chamber in permanently open communication with a cylinder of the engine via a duct, there being provided means for injecting fuel into the mixing chamber during compression of combustion air in the cylinder, the fuel being injected in a direction toward the duct and having the form of a narrow core jet surrounded by fine droplets such that combustion air displaced into the mixing chamber during the compression flows counter-currently to the core jet, and turbulence-producing means disposed within the chamber in the path of the inflowing displaced air and located so as to be outside the core jet, whereby inflowing displaced air impinges on the turbulence-producing means so as to increase the intensity of mixing of the fuel and air.

Abstract: A sealing device between a reciprocator and a stationary encircling housing comprises first and second rolling diaphragms at opposite ends of the reciprocator and exposed to higher and lower pressures, respectively, diaphragm-supporting liquid in first and second chambers in the respective diaphragms, and pumping means which, owing to the reciprocation, pumps liquid from the second chamber to the first. This means comprises an annular seal carried by the reciprocator, sliding on the housing and acting as a piston and as an inlet non-return valve, and another annular seal carried by the housing, sliding on the reciprocator and acting as an outlet non-return valve.
