The moving and stationary components of a piston engine are subjected to static and dynamic stresses that follow the laws of mechanics. The physical and engineering fundamentals of internal combustion engines are presented comprehensively, particularly from the perspective of automotive engines, for both students in the field of internal combustion engines and practicing engineers and engine builders. Furthermore, the book serves, while considering important boundary conditions, to design, calculate, and construct the main assemblies of internal combustion engines and provides an overview of the topic of direct-injection gasoline engines.
