In a combustion engine, operating medium which is preferably air is inducted and compressed before fuel is supplied and combustion takes place while performing work. In response to engine load, a regulatably great portion of the maximum amount of air sucked in at all times is allowed to escape without being compressed. Only the amount of air temporarily required is compressed and supplied with fuel. In this way the working volume of the engine is regulated in response to the actual load. To achieve this, there is included in the engine for each work chamber an exhaust valve which is adapted to be open during a regulatably great portion of the initial phase of the compression movement of the operating means of the engine. |
