In order to respond the increase in required power output of emergency generator engines for data centers and semiconductor factories, Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. has developed an electronically controlled emergency generator engine that is based on our currently marketed S16R2 and has a 10% higher power output while maintaining the same footprint. This engine has achieved improved dynamic performance and emissions performance as well as higher output by being equipped with a common-rail electronically controlled fuel injection system developed in-house. The performance and durability tests of the engine alone have been completed so far. We plan to bring this engine to the market after completing the performance verification of a generating set consisting of the engine coupled with a generator.
