The Physics Of Redline: Secrets of Sky-High Engine Speeds

MARK BRAMLEY AND THE MANUFACTURER spinners how come diesels don’t rev? Automotive diesel engines usually don’t spin past 5000 rpm. Thanks to diesel fuel’s higher energy density and more abrupt combustion, heavier components are necessary. Long strokes that augment torque also add inertial mass, further limiting the redline. airflow We all need oxygen. Straighter intake [...]
