Device for load control and intake air heating of internal combustion engine, comprises separate airflow feeding mechanisms for altering airflow to internal combustion engine via first and second part-pipes

摘要

The device comprises separate airflow feeding mechanisms (8,9) which are arranged in a first and second part-pipes (5,6). The airflow feeding mechanisms alter the airflow to the internal combustion engine, via the first and second part-pipes, independently of each other, between a minimum and a maximum value. The second part-pipe (6) is guided to the exhaust heat exchanger (7) of the exhaust system (4), and then to the internal combustion engine. The second part-pipe has a smaller cross-section than the first one.
