The turbocharger is a highly efficient and compact engine component that has become a staple in modern automotive technology.
The History of Turbocharging
Turbocharging has a rich history that dates back to the early 20th century. The first turbocharger was invented in 1905 by Carl G. Becker, an engineer at the American Turbine Engineering Company. Becker’s design used a turbine to drive a compressor, which compressed air and forced it into the engine’s cylinders. This early design was used in aircraft engines, but it wasn’t until the 1950s that turbocharging became more widely adopted in the automotive industry.

The Science Behind Turbocharging
Turbocharging is a process that uses the exhaust gases of an engine to drive a turbine, which in turn drives a compressor that compresses air into the engine’s cylinders. This process increases the density of the air, allowing for a greater amount of fuel to be burned, resulting in increased power and efficiency. The turbocharger is driven by the exhaust gases, which are hot and high-pressure, making them ideal for driving a turbine.

The Key Components
Büchi’s design consisted of two main components: a compressor and an exhaust-driven axial flow turbine. The compressor was responsible for compressing the air, which was then used to drive the turbine. The turbine, on the other hand, used the exhaust gases to generate additional power. The compressor was powered by the diesel engine, which provided the necessary energy to compress the air. The exhaust gases from the diesel engine were then used to drive the turbine. The turbine was designed to capture the energy in the exhaust gases and convert it into mechanical energy.
The Benefits of Büchi’s Design
Büchi’s design offered several benefits over traditional energy conversion systems. Some of the key advantages include:
Applications and Legacy
