This book is the outcome of many years of research on the subject and it is intended to serve as a reference for engineers and researchers but it should also be useful to (post-graduate) students as a supplementary text. It is expected that the reader is already familiar with (basic) aspects of internal combustion engine operation. Consequently, when dealing, for example, with the combustion development during transients, only a brief reminder is provided at the beginning of the section concerning some fundamental features of (steady-state) combustion, Preface VII and afterwards we focus on the discrepancies and special behavior noticed during transients that diversify the operation from steady-state conditions. Wherever possible, we provide experimental results to support our analysis. There are a few points, however, where this was not feasible due to lack of relevant experimental work (e.g., transient operation when the turbocharger compressor experiences surge or crankshaft transient torsional deformation).
