摘要：
This method is for controlling the intake and exhaust valves of the cylinders of an internal combustion engine which is capable of operating either in four-stroke positive mode or in two-stroke braking mode. The control means pilot the valves so that at least a first exhaust valve of each cylinder (1) is opened (C43) prior to a first instant (t1) when the piston of said cylinder reaches its top dead center position and so that the first exhaust valve is kept in an open state (C43) with a first lift (L1) and for a first predetermined period of time (Δt1), prior to said first instant (t1), and at least an exhaust valve is kept in an open state, with a second lift (L2) higher than the first lift and for a second predetermined period of time (Δt2), after the first instant (t1).
