Abstract
In a reversible-type internal combustion engine including electromagnetically operated gas change valves and a control unit for controlling actuation of the gas change valves, a direction of rotation switch is actuated to reverse engine rotation whereupon the engine is slowed down and uncoupled from the associated drive line and, when the engine speed falls below a predetermined value rotation of the engine in opposite direction is initiated while the timing of the electromagnetically controlled valves is adjusted to the opposite direction of rotation of the internal combustion engine.
