Abstract (en)
[origin: EP0775817A1] The exhaust gas feedback takes the exhaust gas from a collector tube via a switchable regulating unit (7)to the induction air tube. The regulating unit is formed from a throttle point (11) and an exhaust gas valve (12) in parallel with it. Upstream of the regulating device, there is an exhaust gas feedback line (8) with an exhaust gas regulating valve (9). This valve and the exhaust gas valve (12) can be controlled by setting devices (13a, 13b). For a multi-cylinder machine, the regulating device is not connected to all the cylinders.
