Supply system for e.g. direct injection engine of motor vehicle, has control valve recirculating and deviating fraction of exhaust gas in and from exhaust gas recirculation pipe for reducing rotational speed of combustion engine

摘要

The system has a supply pipe (10), and an exhaust pipe (30) situated in downstream of a compressor (11) of a supercharged internal combustion engine (1) e.g. direct injection engine. A turbine (31) is coupled to the compressor arranged in the pipe (10). An exhaust gas recirculation pipe (20) is provided in upstream of the turbine and connects the pipe (30) to the pipe (10). A control valve (21) recirculates and deviates a fraction of exhaust gas in and from the pipe (20) to reduce a rotational speed of the engine. A heat exchanger is arranged between the engine and the compressor. An independent claim is also included for a supplying method for a supercharged internal combustion engine.
