Efficiency of the Otto Cycle vs. Carnot Cycle • There are only two temperatures in the Carnot cycle • Heat is added at T H ... State Diagrams for the Diesel Cycle. Diesel Cycle Otto Cycle The only difference is in process 2-3. Consider Process 2-3 • This is the step where heat is transferred into the Diesel Cycle - Process with P-V and T-S Diagram. The diesel cycle was invented by Rudolph Diesel in 1893. He put forward an idea by which we can attain higher thermal efficiency, with a high compression ratio. All diesel engine works on this cycle. Diesel is used as fuel in this cycle as it can be compressed at higher compression ratio. The following diagrams represent the Otto cycle in a 4-stroke engine in both PV and TS coordinates. The thermodynamic transformations that take place during the Otto cycle are: 1-2. Adiabatic and isentropic transformation (without heat exchange with the outside).
An isentropic process is athermodynamic process in which the entropy of the fluid or gas remains constant. It means the isentropic process is a special case of an adiabatic process in which there is no transfer of heat or matter. It is a reversible adiabatic process. The assumption of no heat transfer is very important since we can use the adiabatic approximation only in very rapid processes. Isentropic Process and the First Law For a closed system, we can write the first law of thermodynamics in terms of enthalpy: dH = dQ + Vdp or dH = TdS + Vdp Isentropic process (dQ = 0): dH = Vdp → W = H2– H1→ H2– H1= Cp(T2– T1) (for ideal gas) Isentropic Process of the Ideal Gas The isentropic process (a special case of the adiabatic process) can be expressed with the ideal gas lawas: pVκ= constant or p1V1κ = p2V2κ in which κ = cp/cv is the ratio of thespecific heats (or heat capacities) for the gas. One for constant pressure (cp) and one for constant volume (cv). Note that this ratio κ = cp/cv...
Otto Cycle is a constant volume cycle on which petrol and gas engines work. The Otto cycle consists of 4 processes and are as follows.
