The final case (5) resulted in a net indicated efficiency of 53.9%
and a brake efficiency of 47.8% with negligible nitric oxide emissions.
To obtain the bmep of 900 kPa, the inlet pressure needed
to be about 170 kPa for case 5. This will require a turbocharger
or supercharger. Since the exhaust gas energy is significantly
decreased (exhaust temperature was 717 K), the use of a turbocharger
may be problematic
