Turbocharging the Automotive Two Stroke Diesel Engine

This paper reports the theoretical and experimental investigation of different combinations of automotive, two stroke, diesel engine with scavenge blower, turbocharger and auxiliary combustion chamber.

The various configurations are compared on a basis of trapped air flow, charge density and power output.

It is shown that freely turbocharged operation of a high speed, two stroke, engine is limited by the low overall efficiency of turbochargers in the size range recommended, and methods of alleviating this problem are described.
