The Diesel cycle is considered as a special case of an internal combustion engine. In the diesel cycle, combustion is controlled in order to obtain constant pressure at the beginning of the expansion stroke. It is important to choose the proper optimization criterion for the optimum design of ...

Carnot cycle n (General Engineering) an idealized reversible heat-engine cycle giving maximum efficiency and consisting of an isothermal expansion, an adiabatic expansion, an isothermal compression, and an adiabatic compression back to the initial state ...
In thermodynamics there are various kinds of cycle such as Rankine cycle,Diesel cycle,Otto cycle etc. Otto cycle is the thermodynamic cycle which uses adiabatic compression process, adiabatic expansion process and constant volume process to calculate the efficiency of the engine.The following Otto ...
The efficiency of an HFC is the fraction of the energy in hydrogen that is converted into useful electrical power. Since an HFC system is not a heat engine, its efficiency is not confined by the Carnot cycle, and hence the HFC efficiency is relatively high. Based on the Carnot theorem, ...
