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.

Detailed Chemical

A chemical method for separating diesel engine piston deposits into various organic and inorganic components is described. The components are subsequently analyzed by infrared spectroscopy. The method is illustrated with examples of deposits removed from the upper lands and upper ring grooves of pistons taken from heavy-duty diesel engine tests. Subtle chemical differences were observed between two deposits removed from upper lands of pistons taken from diesel engine tests which had been carried out with the use of lubricating oils with different formulations. More obvious differences were found between the deposits taken from the upper land areas and the upper ring grooves. These results indicate that a combined chemical and spectroscopic approach has the potential to provide detailed chemical information about engine deposits.
