SIX-STROKE INTERNAL COMBUSTION ENGINE, METHOD OF OPERATION OF SUCH AN ENGINE AND VEHICLE EQUIPPED WITH SUCH AN ENGINE

摘要

This six-stroke internal combustion engine is provided with injection means (121 ) adapted to inject (I3) into at least one of its cylinders (11 ) a liquid (L) containing a reductor agent and/or a precursor for a reductor agent. During the fifth and sixth strokes of a piston (13) within the cylinder (11), this reductor agent can react with NOx molecules in order to clean the gases resulting from the combustion of a fuel mixture within the cylinder.
