摘要： A pressure regulator can be used particularly in a CNG-operated motor vehicle as an electronically controlled pressure reducer for maintaining the gas pressure constant on the injection valve used for filling the respective cylinder. The pressure regulator is composed of a control unit (1), a pressure reducer (3) that is controlled by the control unit (1), and a throttle (2) which connects the gas outlets (20, 40) of the working chamber (17) of the control unit (1) and the pressure reducer (3). A piezoelectric actuator (11) which affects the valve (21, 22) of an overflow device (14) makes it possible to specifically modify the gas pressure (P2) in the working chamber (17) of the control unit (1) and simultaneously influence the position of the valve (38, 39) of the overflow device (33) of the pressure reducer (3), thus allowing the output pressure (Pout) of the pressure reducer (3) to be adjusted to a predefined desired value.

摘要： The invention relates to a method for controlling an injection of an internal combustion engine. The invention provides that after the internal combustion engine is started, the injection and/or the ignition is carried out according to a signal of an absolute position sensor device, particularly according to an absolute position sensor of a camshaft or according to an absolute position sensor of a crankshaft and to an angular range sensor. When a synchronization signal is detected by a sensor wheel of the crankshaft, the following control processes are carried out according to the synchronization signal, i.e. according to the position of the crankshaft. The inventive method is advantageous in that immediately after the internal combustion engine is started, a relatively precise signal for controlling the injection and/or the ignition is available. This enables a more precise combustion shortly after the internal combustion engine is started.

摘要： A method and a control unit are disclosed for controlling a single-cylinder or multiple-cylinder internal combustion engine having at least one fuel injector per cylinder, at least one camshaft for actuating inlet valves and/or outlet valves, and having a control unit which controls the fuel injectors in such a way that they inject in each case one fuel pre-injection per cylinder during a starting phase of the internal combustion engine. In order to make an improved pre-injection strategy possible during the starting phase, according to the invention at least one cylinder pressure signal which is supplied by a cylinder pressure sensor for measuring the pressure in a cylinder is evaluated with regard to interference signals, and the evaluation result is taken into consideration at least during the starting phase in a determination of the camshaft angle.

摘要： The invention relates to an operating method and to a device for a gas-driven internal combustion engine. According to the invention, the pressure in a gas injection system is adapted to the operational state of the internal combustion engine. A higher pressure is adjusted in the gas injection system during a higher charge of the internal combustion engine. Said higher pressure enables a higher volume flow through the gas injection valves associated with the gas injection system. The power produced by the internal combustion engine can be optimized. A lower pressure in the gas injection system is adjusted in the event of a lower charge or if the internal combustion engine is switched off. The lower pressure emits lower pollutant emissions which are produced by the internal combustion engine. The invention is characterized by a bi-directional interface between a control device and a pressure reducer or pressure controller.
