Control Technologies

The Navy pilot program investigated cost-effective technologies to reduce emissions from legacy marine engines. High-speed, high-population engine models in both commercial and Navy fleets were targeted. Emission reductions were sought that would minimize fuel penalty as well as installation and operating costs. Navy operating conditions and fuels limited options. Five highly rated technologies were laboratory tested on a Detroit Diesel Corporation 12V-71N engine using two military and three alternative fuels. Two control technologies were then shipboard tested (baseline, 1-year early degradation, and 9-year late-life). Conclusions and recommendations are provided to inform application of these and similar emission control technologies within both commercial and Navy fleets.

Good Agreement

A computer model for a TBD234V12 marine high-speed diesel engine with 2 turbocharger(2TC) is built on GT-POWER. For validating the computer model, a calculation to the conventional turbocharging system has been done firstly, and the results show good agreement with experimental data. The computer model has then been used for predictive studies of the diesel engine with the proposed STC system on the mapping characteristics. From these results, it can be seen that the STC system can not only improve the part load performance of the diesel engine obviously, but also enlarge the operating range of the marine diesel engine.
