Abstract:
An internal combustion engine (11) comprises an engine block (13) having a cylinder (17), a cylinder head (21) fixed to the block and a piston (31), defining a combustion chamber (51). The piston face (37) has a bowl (39) with a cylindrical wall (41) extending about an axis (43) inclined in relation to the cylinder axis (19). A fuel injector nozzle (55) is mounted in the cylinder head (21) at an inclined angle to the cylinder axis (19) and a spark plug (71) is mounted at an inclined angle to the cylinder axis (19) on the opposite side of the cylinder (17) from the fuel injector nozzle (55). Fuel injected into the combustion chamber (51) is reflected by the bowl (39) in the direction of the spark plug (71).
Abstract:
A fuel injection device works according to the solid energy accumulator principle. A reciprocating piston (10, 14) guided in the cylinder of a reciprocating piston pump (1) driven by an electromagnet (9) delivers portions of the fuel to be injected to the pump area during a practically resistance-free acceleration phase that precedes injection and during which the reciprocating piston (10, 14) accumulates kinetic energy. Fuel delivery is then suddenly stopped by delivery interrupting means (6), so that a pressure shock is generated in the fuel located in a closed pressure chamber, by direct transmission of the accumulated kinetic energy of the reciprocating piston (10, 14) to the fuel located in the pressure chamber. The pressure shock is used to inject fuel through an inection nozzle device (3). The pressure shock generating means that interrupt fuel delivery are located out of the guiding, liquid-tight contact area between the reciprocating piston (10, 14) and the cylinder of the reciprocating piston pump (1).
Abstract:
A fuel injection device works according to the solid energy accumulator principle in which an armature component (10) guided in a pump housing (8) of a reciprocating piston pump (1) driven by an electromagnet (9) is accelerated practically without resistance, the armature component (10) stores kinetic energy and strikes a piston component (14) to generate a pressure shock in a closed pressure chamber in front of the piston component (14), in that the stored kinetic energy of the armature component (10) is transmitted via the piston component (14) to the fuel in the pressure chamber. The pressure shock is used to inject fuel through an injection nozzle device (3). The armature component (10) is guided in a close fit on the piston component (14) and both components are spring-loaded against each other.
Abstract:
The invention concerns a heating system with a combustion chamber into which fuel is fed via a fuel feed unit in the form of an injection device which operates on the energy-storage principle and has a pump (1) and a nozzle device (3) which delivers bursts of fuel in specified quantities. With this fuel burner, it is possible to select both the quantity of fuel injected and the injection frequency independently of any boundary conditions, thereby optimizing levels of harmful pollutants in the exhaust gas and effectively counteracting resonance vibrations in the burner.

Abstract:
A process for controlling the ignition in an internal combustion engine with a device for injecting fuel into a combustion chamber of said engine, in which a control signal for the injection process and a control signal for the ignition process are used. The control signal for the injection process is used to start the measurement of a predetermined delay for the issue of the ignition control signal, as well as for the r.p.m. or load dependent switching to the control of the ignition through the measurement of the crankshaft angle.

Abstract:
The invention relates to a method of operating an internal combustion engine, or an internal combustion engine. According to the inventive method of operation, fuel is injected into a combustion chamber in such a way that it is reflected on a piston. A stratified charge thus arises in the combustion chamber. Choked or unchoked fresh air is sucked into the combustion chamber independent from the load condition of the combustion engine, so that the combustion gas from the previous working cycle is completely expelled from the combustion chamber. Combustion engine power output is substantially produced via the injected quantity of fuel. The inventive method enables a stratified charge, ideal for the combustion of air/fuel mixture, to be obtained. As a result, the internal combustion engine disclosed in the invention runs quietly at ideal combustion gas values.
