Improvement in the Torque Characteristic of a Two-Stroke Opposed Piston Diesel Engine

Abstract

This paper gives details of an investigation into the improvement of the torque characteristics of a turbocharged Commer TS3 two-stroke diesel engine.

At low engine speeds when there is a need for a rising torque characteristic the desirability of using a combustion chamber before the turbine is investigated:

1. (a)

theoretically using a computer matching program, and,

(b)

experimentally by removal of the scavenge blower and incorporating a combustion chamber in the exhaust ducting.

Theoretical and experimental work is reported in this paper.
