Abstract
A single-cylinder, 4-1/2 in. by 5-1/2 in. diesel engine was modified to direct injection. It was supercharged, simulating turbocharging with aftercooling to 89.6 in. Hg absolute manifold pressure and 200 F manifold air temperature.
The maximum bmep was 302 psi at 2400 rpm, which gave an output of 0.915 bhp/cu in. of piston displacement. In order to achieve 1 hp/cu in., a manifold pressure of 98.5 in. Hg absolute would be required at 2400 rpm. The economy was found to improve with high supercharging.
The maximum gas pressure encountered was 2700 psi. This could be moderated by changing either the combustion system or the compression ratio. Changing the compression ratio affected the brake specific fuel consumption only slightly.
