Dr. Alfred Büchi, a Swiss engineer, was the father of Turbocharging as we know it. Buchi went on to license his designs to numerous American (and Foreign) engine companies, many of which are listed in the 1951 advertisement above. A note – these were vastly all 4 stroke engine designs. It was not until the 1950s when Turbocharging on 2 strokes was perfected.
While everyone knows the familiar sound of turbo whistle – The Alco-Buchi Turbosupercharger produced an unmistakable sound.
Check out this fantastic video on YouTube by fmnut, of Ashtabula, Carson & Jefferson Alco S-2 #107, and the distinct sound of a Buchi design turbo.
Turbocharging is a topic I hope to greatly expand upon in time.
