1.1 History of turbocharger.
The man from the invention of machine was trying to achieve the maximum
benefit possible of machine power or how to benefit from unused energy and decrease
cost by decrease the effect of friction and any phenomena making lag in the
performance of machine. Looking at turbocharging from a historical perspective, you
could actually go back to the German inventor Gottlieb Daimler as far back as the late
1800s, or even Rudolf Diesel, who was credited with designing the mechanical
supercharger way back in 1896. But we will be going to continue with Swiss engineer
Dr. Alfred Buchi for the sake of that discussion.
In 1905 Buchi received the first patent for a practical turbocharger-a supercharger
driven by pulses of exhaust gas. In 1910, General Electric started development of
turbochargers. Dr Alfred Buchi (fig 1.1), serving as chief engineer for Sulzer brothers
research department, proposed and produced the first
prototype of a turbocharged diesel engine in 1915.
but it was
not very successful. It was not sufficiently effective to sustain
proper boost energy.1918 was another important year,
possibly the landmark year for turbocharging in the aviation
market. It was this year that Dr. Sanford Moss, a General
Electric engineer, carted a 350-horsepower engine to the top
of Colorado’s Pike ‘s Peak. And there, at 14,109 feet in the
thin air of Colorado’s second-highest mountain peak, Moss
was able to boost the power output of that engine to 356
horsepower. 1920 was also a crucial year in turbocharging ‘s continuing history.
