The basis of this award was the high evaluation of the MACH-30G gas engine, when compared to other engines up to the present time, for major improvements in operating performance making possible significant decreases of CO2, NOx and harmful exhaust emissions. The MHI MACH-30G Gas Engine utilizes minimum quantities of liquid fuel for ignition. The lean air and fuel mixture for the pilot ignition process achieves high efficiency and lessen the effects on the environment. This engine operates at a mean effective pressure of 20 bars and has 12 to 18 cylinders. The rated outputs of these engines cover a range that extends from 3,650 to 5,750kW. Because of the use of the pilot ignition system and combustion control system adopted for these engines, the power generation efficiency ratio has been raised to 42% (100ppm) and 43.5% (200ppm) respectively. The adoption of the common rail system, has made it possible to use a very small quantity of pilot fuel injection (Less than 1% of calorific value) to achieve a level of NOx = 100ppm (O2 = 0%).
In addition, the Customer Support Center at the MHI Yokohama are ready to provide a remote monitoring and diagnostic service that make it possible for MACH-30G users to take advantage of 24-hour operations monitoring service. Since sales of the MACH-30G gas engines were first launched in 2001, orders for 34 engines for use at 16 different plants have been received (includes orders from overseas). Of these engines, 19 are already in commercial service or are undergoing trial operation.
