Summary:

Ethanol has been injected through an atomizing nozzle into the intake manifold of a four cylinder turbocharged diesel engine. It was found that to avoid liquid droplet impingement on the compressor blades the injector needed to be located downstream of the compressor, in the high pressure section of the inlet manifold. 160 proof and 200 proof alcohols were investigated with a series of percentage substitutions at different speeds and loads. The fumigation of ethanol resulted in a slight improvement in thermal efficiency at high loads and a small reduction at light loads. The ignition delay and rate of pressure rise also increased significantly when ethanol was added to the engine. A change in the proof of ethanol from 160 to 200 did not produce any noticeable change in engine performance. Emission measurements were also made and are discussed. The problem of obtaining uniform cylinder to cylinder distribution of alcohol has been encountered
