The thermal efficiency of the ideal diesel cycle is given by equation____ Where, ρ = Cut off ratio, r = Compression ratio.
1
\({\eta _{diesel}} = 1 - \frac{1}{{{r^{\gamma - 1}}}}\frac{{{(\rho ^\gamma } - 1)}}{{\gamma \left( {\rho - 1} \right)}}\)
2
\({\eta _{otto}} = 1 - \frac{1}{{{r^{\gamma - 1}}}}\)
3
\({\eta _{diesel}} = 1 - \frac{1}{{{r^{\gamma - 1}}}}\frac{{\gamma({\rho } - 1})}{{ \left( {\rho^\gamma - 1} \right)}}\)
