The engine designed by Lenoir was essentially an atmospheric engine based on the early steamengines. In this, a combustible mixture was contained in a cylinder: it was ignited and the pressureincreased isochorically to the maximum level. After this the gas expanded isentropically throughan expansion ratio, re, during which it produced work output. The air-standard cycle returned thegas to state 1 through an isochoric expansion to p₁ and an isobaric compression to V1.Assume p₁ = 1 bar, T₁ = 15 °C, p2 = 10 bar and the expansion ratio, re = 5. Calculate thespecific work output and thermal efficiency of this cycle. How does this compare with theefficiency of an equivalent Carnot cycle?[650.30 kJ/kg; 34.97%; 90.0%]

A Joule cycle is used for electricity production in a power plant. Air is introduced to the cycle from the ambient with a pressure of 1 bar, and a temperature of 20 °C. The air is compressed in compressor C1 and is thereafter cooled down to 30 °C. The air is compressed again in compressor C2. The air passes through a regenerator where it is heated by exhaust gases. Heat is added by combustion of fuel in combustion chamber CC1. The air is thereafter expanded in turbine T1. The air is reheated in combustion chamber CC2.
