Practical Engine Airflow
Performance Theory and Applications
Livre / Workshop en anglais de John Baechtel
Baechtel covers the primary factors for optimizing the airflow path. This includes the fundamentals of air motion, air velocity, and boundary layers; obstructions; and pressure changes.
Flowing air through the heads and the combustion chamber is key and is comprehensively explained. Also comprehensively explored is the exhaust system's airflow, in particular primary tube size and length, collector function, and scavenging.
Chapters also include flowbench testing, evaluating flow numbers, and using airflow software.
