Estimation of Nitrogen Oxide Emission Reduction in a Boosted Truck Diesel Engine with Two-Stage Charging and Miller Cycle

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.

Engine Type

An experimental investigation of nitrogen oxides (NOx) emission reduction from a diesel engine using the Miller cycle was carried out. A Lister-Petter diesel engine, type TS2, was used for the experiments. Three versions of Miller cycles were designed and realized on a diesel engine. A series of tests were carried out on the test rig to compare the performances and emissions of the original engine (standard dual cycle) with those of the three versions of Miller cycles. The test results from the standard dual cycle and from the three versions of Miller cycles showed that applying Miller cycle to the diesel engine could reduce the NOx emission from the diesel engine. The reduction ratios of NOx for the Miller cycles are from 4.4 to 17.5 per cent. The best reduction effect is Miller cycle 1 and the reduction rates of NOx are from 11.0 to 17.5 per cent.
