Abstract: A method for determining a gas consumption of a gas-powered gas engine or a gas-powered dual-fuel engine. The engine is operated under actual operating conditions, and the actual gas consumption of the engine is acquired under the actual operating conditions. A target gas consumption of the engine to be anticipated under target operating conditions is calculated depending on the actual gas consumption and depending on discrepancies between the actual operating conditions and the target operating conditions.

Abstract: A method for optimizing the operating and combustion processes of a diesel engine with common rail injection and a turbocharger includes injecting fuel into each combustion chamber of the diesel engine by a main injection and a post-injection which follows the main injection and controlling a start time and a quantity of the post-injection as a function of an end of the main injection and as a function of operating parameters of the diesel engine using an electronic engine control unit and an input-output map stored in the electronic engine control unit. The post-injection is initiated at a point 30–180° of rotation of a crankshaft of the diesel engine after the end of the main injection, and the quantity of the post-injection is adjusted to 20–30% of a quantity of the main injection.
