Reached by the gas is T H , and the coldest temperature during the cycle The maximum and minimum gas temperatures during the cycle.Ĭarnot's result was that if the maximum hot temperature This simplest heat engine is called the Carnot engine, for which one complete heating/cooling,Įxpanding/contracting cycle back to the original gas volume and temperature isĪ Carnot cycle, named after Sadi Carnot who in 1820 derived the correctįormula for the maximum possible efficiency of such a heat engine in terms of Most work we can possibly get for a given amount of fuel in a cyclical process? We’ll examine here the model stripped to itsĪ cylinder, with external thermal connections to supply and take away heat, andĪ frictionless piston for the gas to perform (and if necessary absorb) Our aim in this lecture is to figure out just how efficient Next cycle begins, otherwise all the work the gas delivered on expanding will Heat and/or the gas must therefore be dumped out of the cylinder before the To turn heat into work, but that’s a one shot deal. Supplying heat to a gas, the gas then expands in a cylinder and pushes a piston Michael Fowler The Ultimate in Fuel Efficiency for a Heat EngineĪll standard heat engines (steam, gasoline, diesel) work by
