In this century, it is believed that crude oil and petrolem products will become very scarce and costly. Day-to-day, fuel economy of engines is getting improved and will continue to improve. However, enormous increase in number of vehicles has started dictating the demand for fuel. Gasoline and diesel will become scarce and most costly in the future. With increased use and the depletion of fossil fuels, alternative fuel technology will become more common in the coming decades.

This book covers the various approaches to modelling and optimising the spray and mixture formation processes in modern internal combustion engines. Due to their complexity and importance in predicting the temporal and spatial distribution of liquid and gaseous fuel inside the cylinder, special emphasis is put on the detailed description of multi-dimensional CFD-models.
