Moreover, the first originally developed multi-fuel engine was delivered in 1992, and the manufacturing results of over 36,000,000kW(49million PS) in total are possessed.
Driven by environmental awareness, IMO (International Management organization) determined to enhances emission regulations. The interest in gas as fuel for shipping is increasing to fulfill the rigid regulation.
