Summary

Nowadays, almost every manufacturer of petrol or diesel engines relies on the turbocharger to increase performance, but at the beginning of the 1970s this was still the exception rather than the rule. However, there was already decades of experience with the supercharger. Both technologies had similar goals and led to impressive increases in engine performance, but the path was different. This article takes a look back at the beginnings and heyday of the supercharger and looks at the progress made with the turbocharger at the beginning of the 1970s.

This article contains the following chapters

Superchargers driven by the crankshaft
Learned from Nazzaro
Mickey Mice to inflate
Born for the supercharger
Supercharged two-stroke for the Avus race
The magic of the silver pipes

Preview (beginning of the article)

When a wild Ford Capri suddenly leaves the pack of competitors behind in a stock car race and vehemently "barrels" its way to the front, older members of the audience may find themselves transported back to racing scenes from the 1930s. Back then, it was the supercharged cars that suddenly "revved up" - acoustically impressive - and set off into a sprint that either brought them victory or an overtaxed machine that suddenly gave up the ghost. The idea of adding an additional quantity of mixture to the amount of gas sucked into the cylinder by the piston had already been put into practice by Gottlieb Daimler. At that time, additional air was forced into the combustion chamber through valves in the piston crown when the piston approached bottom dead center.
