Steam injected diesel engine and EGR

What is it about?

An engine test with steam injection and EGR is conducted for investigating the effects of engine design parameters such as compression ratio (CR), charge temperature and pressure and equivalent ratio on a directinjection diesel engine performance and NO emissions using zero-dimensional single-zone combustionmodel.the model are validated and well suited with those experimental studies of the diesel engines running with 20%steam ratio and 10%EGR, some important design parameters are investigated by using the theoretical model.

Why is it important?

there is no study to investigate effects of engine design parameters on the performance and NO emissions of steam-injected diesel engine with EGR. Hence, in this study, a direct injection (DI) diesel engine equipped with an electronically controlled steam injection system developed by Parlak et al. [13,14] and coupled withEGRis used to compare the effects of engine design parameters such as CR, inlet pressure (at same equivalence ratio or same fuel amount) and IT on NO emissions, effective power and efficiency, and in-cylinder temperature and pressure.

Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. This article also lead to decrease NOx emission in engines having waste heat recovery system in ships as they have also steam system.
