Catalyzer i.e. precatalytic converter, heating method for control device, involves determining measure for temperature at input of converter, and carrying out additional injection, if temperature exceeds preset threshold value

摘要

The method involves operating an internal combustion engine (10) with sub-optimal injection angle efficiency and partition of fuel amount to partial injections before beginning of combustion. Torque loss resulting from the efficiency and/or partition is compensated. The amount and filling are coordinated so that an air rate of chamber fillings is larger than 1. A measure for temperature is determined at an input of a precatalytic converter (28), and an additional injection is carried out after beginning, if the temperature exceeds a preset threshold value. An independent claim is also included for a control device of an internal combustion engine working with direct injection of fuel in its combustion chambers.
