Heavy Duty Diesel

Synthetic fuels produced from non-petroleum based feedstocks can effectively replace the depleting petroleum based conventional fuels while significantly reducing the emissions. The zero sulfur content and the near zero percentage of aromatics in the synthetic fuels make them promising clean fuels to meet the upcoming emissions regulations. However due to their significantly different properties when compared to the conventional fuels; the existing engines must be tested extensively to study their performance with the new fuels. This paper reports a detailed in-cylinder pressure measurement based study made on adaptability of the engine control module (ECM) of a modern heavy duty diesel engine to optimize the engine performance with the F-T diesel fuel. During this study, the F-T and Conventional diesel fuels were tested at different loads and various injection timing changes made with respect to the manufacturer setting. Results from these tests showed that the ECM used significantly different injection timings for the two fuels in the process of optimizing the engine performance. For the same power output the ECM used a 2° advance in the injection timing with respect to the manufacturer setting at the full load and 1° retard at the no load condition. While the injection timings used by the ECM were same for both the fuels at the 50% load condition. However, a necessity for further changes in the control strategies used by the ECM were observed to get the expected advantages with the F-T fuels.

The Impact

Investigating the impact of jet fuel on diesel engine performance and emissions is very important for military vehicles, due to the US Army Single Fuel Forward Policy mandating that deployed vehicles must refuel with aviation fuel JP-8. There is a known torque and fuel economy penalty associated with the operation of a diesel engine with JP-8 fuel, due to its lower density and viscosity. On the other hand, a few experimental studies have suggested that kerosene-based fuels have the potential for lowering exhaust emissions, especially particulate matter, compared to diesel fuel #2 (DF-2). However, studies so far have typically focused on quantifying the effects of simply replacing the regular DF-2 with JP-8, rather than fully investigating the reasons behind the observed differences. This research evaluates the effect of using JP-8 fuel in a heavy-duty diesel engine on fuel injection, combustion, performance, and emissions, and subsequently utilizes the obtained insight to propose changes to the engine calibration to mitigate the impact of the trade-offs. Experiments were carried out on a Detroit Diesel Corporation (DDC) S60 engine outfitted with exhaust gas recirculation (EGR). The results indicate that torque and fuel economy of diesel fuel can be matched, without smoke or NO x penalty, by increasing the duration of injection to compensate for the lower fuel density. The lower cetane number of JP-8 caused an increased ignition delay and increased premixed combustion, and their cumulative effect led to relatively unchanged combustion phasing. Under almost all conditions, JP-8 led to lower NO x and particulate matter (PM) emissions and shifted the NO x-PM trade-off favourably.
