Abstract: The paper outlines a computationally efficient analytical method to evaluate fuel consumption and NOx emissions during manoeuvres pertaining to the New European Drive Cycle (NEDC). An integrated optimisation procedure is also included in the analysis to minimise the Brake Specific Fuel Consumption (BSFC) and NOx emissions as objective functions. A set of optimum gear ratios are determined for 4, 5 and 6-speed transmission systems as the governing parameters in the optimisation process. The analysis highlights the determination of gear shifting strategies, based on the minimisation of either of these declared objective functions. A 7.5% reduction in the BSFC and 6.75% in NOx are attainable in the best case scenario for a 6-speed transmission and a gear shifting strategy, based on the least BSFC for the case of the chosen engine. The novel integrated analytical simulation and multi-objective optimisation has not hitherto been reported in literature. It provides the opportunity for objective intelligent-based approach to the use of gear shifting indicator technology. Results of this study also show that transmission optimization can act as an effective and inexpensive means to enhance fuel efficiency and reduce emissions.
