What is it about?
Highlights *Impact of different IVC timings on performance of CRDI engines fueled with butanol-diesel blends has been studied. *A computational modeling is developed by the chemical kinetics mechanism. *Peak in-cylinder pressure is increased for all early inlet valve close timings for all n-butanol diesel blends. *Increase in ignition delay is for later inlet valve close timings.

Why is it important?
The aim of the study reported in this article is to examine the benefits of early inlet valve closure timings for different injection timings. However, the influence of different operational variables on the use of butanol–diesel blends has not been previously studied with respect to a common rail direct-injection diesel engine. Further investigation of the effect of biobutanol–diesel blends on CRDI engines with CFD simulations is scant. CFD simulations offer the prospect of achieving a deeper insight into comprehending incylinder combustion.
Perspectives
In the present study, numerical investigations were carried out to determine the effects of n-butanol–diesel blend ratios and IVC timing on the combustion and exhaust emission characteristics of CRDI engines.
