From the above equation, it can be observed that the efficiency of the Otto cycle is mainly the function of compression ratio for the given ratio of Cp and Cv. If we. Probably the most well established and modelled compression and expansion process in the power chamber of an internal combustion engine is the Otto cycle. OTTO CYCLE. Efficiency is given by. Efficiency increases with increase in compression ratio and specific heat ratio (γ) and is independent of load, amount of.
Heat is supplied only during the constant volume processes 2—3 and heat is rejected only during the constant volume processes 4—1. As the piston is capable of moving along the cylinder, the volume of the air changes with its position in the cylinder. The increased high pressure exerts a force on the piston and pushes it towards the BDC. Laws Zeroth First Second Third. The work and heat terms can then be calculated.
