Abstract:
A method and apparatus for starting and regulating valve systems for displacement-type machines such as fuel-regulated internal combustion engines wherein a valve can be held in at least two final operational positions. The valve systems are each designed as an oscillating spring/mass system such that periodic force components or travel path excitations can be communicated to the spring/mass system in its original starting position or in a static home position. The pulse characteristics or frequency of the force components or excitations are close or equal to the natural frequency of each spring/mass valve system, so that the valve system is caused to oscillate with an increasing amplitude and is thus excited into one of the two final operational positions.
Abstract:
A method and apparatus for introduction of a fluid or liquid medium into working or operating chamber of an internal combustion engine is disclosed. For the purpose and object of reduction of nitric oxide emission as well as for an improvement of the efficiency there is proposed with a method and apparatus for introduction of the fluid or liquid medium into the working or operating chamber of an internal combustion engine operated with gaseous fuels to admix the fluid continuously or intermittently as to the gaseous fuel and subsequently to blow-in the fuel or power gas/fluid or liquid mixture into the working or operating chamber of the internal combustion engine under the pressure of the fuel or power gas. Hereby there can be utilized or employed advantageously besides the water also alcohol and alcohol/water mixtures, which means media with bound OH-groups.
Abstract:
An electromagnetically operating actuator for control elements capable of making oscillatory movements in displacement machines, more particularly for flat slide shut-off valves and lift valves, includes a spring system and a pair of electrically operating switching elements, over which the control element is movable in two discrete opposite operating positions and is retained thereat by either switching magnet, the locus of the position of equilibrium of the spring system lying between the two operating positions. The invention is characterized by the provision of a compression device in engagement with the spring system for relocating the locus of the position of equilibrium of the spring system upon actuation of the compression device.
Abstract:
A device for feed control of valve-controlled internal combustion engines, with the combustion chamber capable of being closed off by an intake valve toward the intake passage, and with a further shutoff element being provided in the intake passage. This further shutoff element is a slotted flat slide valve which is movable in an oscillating manner and cooperates with counter slots. The counter slots are formed by vanes arranged in the housing. The flat slide valve is drivable by a cam.
Abstract:
A fuel injection system for single or multiple cylinder internal combustion engines comprises two fuel injection valves for each cylinder of an engine. One fuel injection valve operates to inject a principal volume of fuel and the other a secondary volume of fuel into said cylinder. The two injection valves are fed by a plunger which is reciprocable in the working chamber of a pump body. The working chamber of the pump body communicates with a fuel admission duct, a delivery duct for the delivery of a principal fuel volume to the one fuel injection valve and a delivery duct for the delivery of a secondary fuel volume to the other fuel injection valve in such a manner that the duct for the delivery of the principal fuel volume is covered by the plunger after the same has completed a predetermined part of its stroke.
