(a) Compare otto, Diesel and Dual combustion cycle on the basis of compression ratio, same compression ration and same Heat input and constant maximum pressure and heat supplied.
(b) In a constant volume "otto cycle" the pressure at the end of compression is 15 times that at the start, the temp. of air at the beginning of compression is 38oC. Determine :
(i) Compression ratio (ii) Work done (iii) Thermal efficiency of the cycle
