Abstract
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.
