1903 Wright brothers achieve powered flight.
The first exhaust-driven supercharger was developed by Dr. Alfred J. Büchi of Switzerland between 1909 and 1912. Dr. Büchi was Chief Engineer of Sulzer Brothers Research Department and in 1915 proposed the first prototype of a turbocharged diesel engine, but his ideas gained little or no acceptance at that time.

1912 Titanic hits iceberg..
Experimental turbocharging plant opened in Sulzer Bros Ltd, Winterthur, Switzerland in 1911.

1928 Fleming discovers penicillin.
1925 marked the first successful application on 2 German ships fitted with 2,000 hp turbocharged diesel engines. This success led to Büchi licensing many manufacturers in Europe, USA, Japan.

1930 Amy Johnson flies solo to Australia.
1930s Turbochargers with axial turbines used in marine, railcar and large stationary applications.

1943 Colossus is world's first computer.
In the 1940s the advent of the aircraft gas turbine led to major advances in materials technology and design. This had the following implications for turbocharging :-
• development of improved heat resisting materials
• development of precision casting techniques for high temp materials
• this allowed the development of radial turbines and led to the use of radial flow turbos on small automotive diesel engines.

1953 Crick and Watson discover structure of DNA.
Major engine producers such as Cummins,
Volvo and Scania start experimenting with turbocharged engines for trucks using turbochargers supplied by Elliot and Eberspächer. These early designs were unsuccessful due to the large size of the turbocharger. German engineer, Kurt Beirer produces an innovative compact design that is taken up by Schwitzer Corporation, Indianapolis. In 1954 Cummins offer a range of turbocharged engines, the VT12, six cylinder NT, NRT's and JT's.

Also in 1954, Volvo offered their first turbocharged truck diesel, the TD96AS, rated at 185 bhp compared with the 150 bhp naturally aspirated D96AS.

Pole position at Indianapolis in 1952 won by a car powered by a turbocharged Cummins engine.


   

In 1954 Holset identified turbocharging as a key future technology and starts manufacturing turbochargers.

Today, Cummins Turbo Technologies continues to produce the Holset range of turbochargers for the worlds leading OEM's.
