Internal combustion engine with return line for exhaust gases

摘要

An internal combustion engine with a return line for exhaust gases which connects the exhaust system with an inlet line provided with a throttle valve; the orifice of the return line in the inlet line is thereby located within the control cross section of the inlet line so that with a closed and substantially closed throttle valve, the orifice is upstream of the throttle valve whereas with an opened or substantially opened throttle valve, it is disposed downstream thereof.
