Direct injection engine with stratified exhaust recirculation

Each cylinder in the area of BDC (UT) of the piston movement has two exhaust gas inlet apertures for exhaust, gas feed-back channels (30, 30') which are connected to other cylinders. Additionally, each cylinder has at least two further exhaust gas inlet apertures, which are arranged displaced r...

Beschreibung
Zusammenfassung:	Each cylinder in the area of BDC (UT) of the piston movement has two exhaust gas inlet apertures for exhaust, gas feed-back channels (30, 30') which are connected to other cylinders. Additionally, each cylinder has at least two further exhaust gas inlet apertures, which are arranged displaced radially to the cylinder periphery. The exhaust gas inlet apertures are so arranged that with their aid back-fed exhaust gas into the cylinder forms a rotating, somewhat pot-shaped gas collection with a limit line (17), in the inner space of which fresh air (15) from the air inlet valve (18) can be concentrated. ADVANTAGE - Lowers the fuel consumption of a direct injection internal combustion engine to that of a diesel engine.
