Source sentences:
text: Combustion engines are heat engines driven by the heat of a combustion process.
text: Internal combustion engines are heat engines, and as such their theoretical efficiency can be approximated by idealized thermodynamic cycles.
text: This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to be reached with less fuel, while giving a longer expansion cycle, creating more mechanical power output and lowering the exhaust temperature.
