Most engine technology books are difficult to read, use jargon and waffle on subjects that are not useful to the reader. This book aims to give the reader knowledge around the methods and equations used for rolling road standards, the difference in performance between turbocharged and naturally aspirated engines, including graphs and calculations to explain and show the results found during this study. A whole system review is also carried out, considering how to improve airflow through an engine. Giving the reader information behind each rolling road standard, turbocharged and naturally aspirated engines, and airflow through an engine. Containing useful references for more background reading if desired, this book is your one stop shop to covering turbocharged verses naturally aspirated engines!
