Method for controlling combustion of direct injection diesel engine of passenger car, involves calculating combustion form rate as reference parameter for controlling combustion of combustion engine based on intermediate value

摘要

The method involves determining a value of a given operating parameter, where the value represents control start of main injection. Another value of the operating parameter is determined and represents 50 percentage operating position of a normalized or non-normalized integral heating process. A geometrical intermediate value is calculated from the values. A combustion form rate is calculated as a reference parameter for controlling combustion of an internal combustion engine based on the intermediate value, where a crank angle value of a cylinder (1) is determined as the operating parameter. An independent claim is also included for a device for controlling combustion of a direct injection diesel engine.
