The Otto Cycle is presented in the p - V and T - s diagrams and its major performance trends (thermal efficiency and power output) are plotted in a few figures as a function of compression ratio, combustor outlet temperature and some fixed cylinder geometry. It should be noted that this ...
So during the cycle, gas doesn't enter or leave the cylinder. So the only thing that's changing is the temperature. So the question is what's the change in temperature for step 1? Well, if we want to relate pressure and volume like on a p v diagram to temperature, we need...

The Diesel cycle diagram is shown in Figure given below.To model the cycle, the input variables considered are maximum pressure (pmax)(pmax), minimum pressure (pmin)(pmin), maximum volume (vmax)(vmax), cut-off ratio (rc)(rc), and adiabatic exponent \mathrm{(\gamma)}. The ...
If the maximum temperature in the cycle (T4s) is 2400 R, determine the Otto cycle hot ASC thermal efficiency of this engine. Assume all the other variables remain unchanged. Answer: (ηT)Otto hot ASC = 52.8%. The actual pressure–volume diagram from an engine operating on a gas or vapo...
1) otto cycle 奥托循环1. Considered the complex cycle, the efficiency for a gasoline engine is more similar to the actual efficiencythan the usual Otto cycle. 汽油机的实际工作循环是由两个子循环组成的复合循环,由此计算的热效率比通常奥托循环计算的更接近汽油机热效率的实际值。

There are four different processes in the Otto cycle, out of which two are adiabatic and two are constant volume processes. The relation between the pressure and temperature for an adiabatic process is given as: TfinalTinitial=(PfinalPinitial)(γ−1γ) where γ is the ratio of s...

Finally, we analytically characterize the complete phase diagram of the Otto cycle for both driving schemes and highlight the different operational modes of the cycle as a heat engine, refrigerator, accelerator, and heater.Singh, VarinderCenter for Theoretical Physics of Complex Systems, Institute for...
