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.
Claims8
A reversible reciprocating internal combustion engine including a piston movably disposed in a cylinder, gas change valves and electromagnetic actuators for operating said gas change valves, a control unit for controlling actuation of said gas change valves, a direction of movement switch for indicating to said control unit the desired direction of rotation of said internal combustion engine, and a direction of rotation monitor associated with said engine for sensing the direction of rotation and a stand still of said engine, as well as the position of the respective piston and supplying that information to said control unit for controlling said electromagnetic actuators.
