Fundamental parameters of an engine, Part 2/3
What is the influence of the number of cylinders on the performances ? Why are the dimensions of bore and stroke, which determine the displacement, a compromise ? What are the parameters influencing the performance characteristics of an engine ?

The second part of this file will guide you step by step towards the comprehension of the fundamental parameters ruling the architecture of the automotive engine.
