Jg. Hawley et al., AN ASSESSMENT OF THE EFFECTS OF OPERATING A DIESEL-ENGINE ON AN ATMOSPHERE OF OXYGEN AND CARBON-DIOXIDE, Journal of the Institute of Energy, 67(473), 1994, pp. 138-142
Experimental work at the Royal Naval Engineering College and the Unive
rsity of Exeter has demonstrated that a diesel engine operating on rec
ycled combustion products has sufficient potential to warrant consider
ation for Autonomous Underwater Vehicle (AUV) applications. Results ar
e given for a Perkins T4.236 diesel engine operating on O-2/CO2 mixtur
es. The effect of CO2 concentration and inlet-gas preheat has been stu
died in relation to the torque, power output, fuel consumption, exhaus
t-gas temperature, cylinder pressure and combustion characteristics. T
he engine operates satisfactorily on a 30% O-2/70% CO2 mixture but, in
comparison with the naturally aspirated engine, a degradation in the
performance is observed amounting to a reduction of 20-23% in brake po
wer and, more seriously, an increase of 23-28% in brake specific fuel
consumption under maximum-torque conditions.
