| 摘要 |
The invention relates to a volume-controlled four-stroke reciprocating internal combustion engine comprising a first cylinder, in which a first piston that is operationally connected to a crankshaft via a first connecting rod, is arranged so as to be displaceable in a reciprocating motion, and at least one second cylinder, in which a second piston that is operationally connected to the crankshaft via a second connecting rod is arranged so as to be displaceable in a reciprocating motion. The engine further includes a fresh air tract for the second cylinder, in which an expansion/compression machine is arranged in the direction of flow of fresh air before a gas exchange inlet valve of the second cylinder, wherein the expansion/compression machine is the first cylinder. The volume-controlled internal combustion engine as per the invention has great potential for saving fuel and thereby for reducing CO2. |
