Turbo Compounded Engine


Turbo compounding technology will help powertrain crankshafts to turn via hydrodynamic coupling


The turbo compounding technology is relatively a new one and will use exhaust gasses to provide additional power directly to the crankshaft of powertrain. The turbo compounding mechanism will be coupled to the crank shaft of the engine via two different techniques, hydrodynamics coupling or by using the gearing technology.

There is a chance of using power generators to produce electric power. These generators will also run via Turbo Compounding. This technology is not new because the aerospace industry has been using it since 1940. However, it is brand new for the car engines and it could be the next big thing in the energy recovery techniques.

The turbo compounding is the way to reuse the exhaust gases to facilitate the engines by providing more turbo power.

If you take a close look at the cross sectioned diagram given above, then you will be easily able to understand the working principle of turbo compounding mechanism.

On the upper right side there is a compressor shown with blue arrows, will get power from the turbine wheel to its left. It sends the boosted air intake to the engine chambers. The turbine then further transfers the exhaust gases on the next turbine in the line, fitted at the shaft that drives a set of gears. This is not a common gear set, it uses highly ration transmission to ultimately couple it with crankshaft.

Bowman is famous for its electrical compounding systems for power generation and commercial sector vehicles. One of their statements says, the turbo compounding technology will boost up the efficiency of engines by seven percent with no negative impact on the mechanical of an engine. While mechanical compounding showed a gain in performance by five percent.

The turbo compounding technology is the thing of the past from the aerospace industry but how it will impact on the performance of the automotive industry, is the present mania for engineers and engine experts.
