Many combustion engines in cars, ships, planes, trains, off-highway trucks and power plants increase their efficiency and power output with a turbocharger mounted on the engine. The turbocharger uses the engine’s exhaust gas to turn a compressor which draws in ambient air and compresses it before it enters the combustion chamber at increased pressure. Higher air pressure in the combustion chamber results in higher engine performance. This innovative idea was patented in 1905 by Alfred Büchi, a Swiss engineer and continues to be a solution for operating efficient fossil fuel powered engines.
The ABB Power2 800-M second generation two-stage turbocharging system is assembled on the engine that has achieved a Guiness World Record title for the most efficient four-stroke engine. The ABB Power2 800-M is the most powerful as well as most compact two-stage turbocharger for four-stroke engines.
By reaching an air pressure of up to 12 times the norm, two-stage turbocharging solution has an efficiency of more than 75 percent, compared to up to 70 percent efficiency of a single-stage turbocharger. The turbocharging efficiency of the ABB Power2 easily translates into a six-figure savings in fuel yearly and significant cuts in emissions – up to 60 percent less NOx emissions.
