    Development of High-efficiency 2MW High-speed Gas Engine (Completes 9,000+ Hour Validation)

    Mitsubishi Heavy Industries Engine & Turbocharger, Ltd.

    In the segment of distributed power sources, power generation by means of a gas engine holds an important position since gas engines emit less CO2 from burning natural gas than coal and heavy oil, i.e., its exhaust emissions are cleaner and its thermal efficiency is fairly high. Nevertheless, the key that attracts customers and motivates them to purchase one is how economical the unit price of a gas engine power generation is, compared with the unit price of power from the grid. Namely, the product merchantability is dependent on the realization of appealingly high generation efficiency. It is also key to design the engine with the smallest dimensions possible, especially for installation at sites in urban areas. To meet these needs, Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. Has been developing the new 2MW-class G16NB gas engine, which features the world's most advanced combustion control and turbocharging technologies. An overview of the G16NB engine is described below.
