Expected Increase

This paper will cover a method for inline blending biodiesel and the initial testing of fuel blends for a Wartsila TM620, inline six cylinder, 4-stroke, 400 rpm, diesel engine generator set rated at 7.8MW. To facilitate this initial testing 6,000 gallons of Recycled Frying Oil Methyl Ester (RFO-ME) was delivered by ISO tank container from Oahu. The testing objective was to design a system that would facilitate emissions data collection for numerous blends, gain experience using the fuel, and to determine if nitrogen oxide emission levels would exceed our air permit. Engine performed well on all fuel blends, with a greater than expected increase in nitrogen oxide emissions, but within the limits of the air permit. Neat biodiesel (B100) resulted in an increased thermal efficiency when compared to #2 diesel. Inline blending is a safe effective method to control fuel blends.

The Impact

In the present paper, a model-based controller of engine torque and engine-out Nitrogen oxide (NOx) emissions, which was previously developed and tested by means of offline simulations, has been validated on a FPT F1C 3.0 L diesel engine by means of rapid prototyping. With reference to the previous version, a new NOx model has been implemented to improve robustness in terms of NOx prediction. The experimental tests have confirmed the basic functionality of the controller in transient conditions, over different load ramps at fixed engine speeds, over which the average RMSE (Root Mean Square Error) values for the control of NOx emissions were of the order of 55–90 ppm, while the average RMSE values for the control of brake mean effective pressure (BMEP) were of the order of 0.25–0.39 bar. However, the test results also highlighted the need for further improvements, especially concerning the effect of the engine thermal state on the NOx emissions in transient operation. Moreover, several aspects, such as the check of the computational time, the impact of the controller on other pollutant emissions, or on the long-term engine operations, will have to be evaluated in future studies in view of the controller implementation on the engine control unit.
