Abstract:
1. A method for optimizing the operating and combustion processes of a diesel engine with common rail injection and a turbocharger, comprising the steps of: injecting fuel into each combustion chamber of the diesel engine at least 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, wherein said step of controlling comprises initiating the post-injection at a point 30–180° of rotation of a crankshaft of the diesel engine after the end of the main injection, and adjusting the quantity of the post-injection to 20–30% of a quantity of the main injection.
