Title: Diesel engine 2-stroke versus 4-stroke cycle design in rail traction

Description: Two-stroke cycle and four-stroke cycle diesel engines are in use in rail traction with four-stroke cycle design dominating the field. Cycle simulation by computer programmes have shown that the conventional two-stroke cycle is inferior to its four-stroke cycle counterpart in combustion efficiency and thermal loading. Research at Sulzer Brothers Ltd., to decide on the choice of cycle for production of a high power locomotive engine concluded that. conventional two-stroke cycle engine is not suitable for locomotive application. A report by Ricardo Ltd., based on a survey of engines in current production for traction application suggested that there are potentials in two-stroke cycle design . This research project is concerned with comparison of two well proven locomotive engines, one of two-stroke cycle and the other of four-stroke cycle. Performance, mechanical loading, thermal loading and vibration were chosen as parameters to be investigated to provide information about the status of the two cycles in relation to lower range, fuel consumption, reliability and durability, with a view to assist the users of locomotive engines to make the correct choice. Results and analysis of these findings are presented.
