Abstract

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.
