The exhaust gas recirculation system reduces the toxicity of exhaust gases.

Through the recirculation system, some of the gases returns to the cylinders for their afterburning.

The main element of the system is the valve, which, with high crankshaft revolutions, skipping exhaust gases to the inlet tract.

Before entering the inlet, exhaust gases are cooled in the recycling system cooler.
