IHI Co., Ltd. Full-scale launch of medium-speed marine engine with electronically controlled fuel injection, the first in the same class in Japan

IHI Corporation
Started full-scale sales of a medium-speed marine engine with electronically controlled fuel injection, the first in the same class in Japan
– Halves harmful substances in exhaust gas –

IHI Power Systems Co., Ltd. (Location: Chiyoda-ku, Tokyo, President: Mao Akamatsu, hereinafter referred to as “IPS”), a group company of IHI, has developed a Niigata 6MG28HX-CR engine that uses an
electronically controlled fuel combustion device (common rail system). We are pleased to announce the release of the medium-speed engine (hereafter referred to as “this engine”). This is the first 1,838 kW-class, 4-cycle*1 medium-speed marine engine that uses a common rail system and is the first in Japan to be sold. and CO2 reduction.

Development of this engine began in response to market needs for improved economic efficiency and environmental performance. For about five years from 2017, Nihon Eisen Co., Ltd. (located in Kobe City, Hyogo Prefecture; President: Tetsuro Nishio), a member of the MOL Group, a major shipping company, and Eikichi Shipping Co., Ltd. (located in Okayama, Japan) of the Senko Group, a general logistics company. Tamano City, President: Toshiyuki Shoji), a tugboat that assists other ships in berthing and docking, was tested and the specified evaluation results were obtained in terms of economic efficiency, reliability, and environmental superiority. to start full-scale sales.
This engine uses a common rail system in which fuel pressurized by a pump is stored in a pipe (common rail) and injected into the combustion chamber by electronic control. In addition to reducing total PM emissions by approximately 50% compared to conventional engines, fuel efficiency can be improved by approximately 6% under low-load conditions, and the amount of soot contained in the exhaust gas (exhaust smoke concentration) is reduced by approximately 38%. Is possible.
The Niigata Common Rail System, which has been proven to operate under severe operating conditions on tugboats that require load
fluctuations, can be optimally adjusted according to the operation form of various ships according to the needs of each customer. The main hardware of the common rail system adopts equipment developed in-house within the group, and is characterized by the ability to provide consistent services.

IPS has worked to realize a low-carbon and decarbonized society by developing and selling Japan’s first hybrid propulsion system for tugboats, which uses storage batteries in the same way as hybrid vehicles, and a dual-fuel engine that uses LNG as the main fuel. I have come. Currently, we are proceeding with the construction of an electric propulsion system as system integration and the development of an ammonia-fueled marine engine.
IHI and IPS will continue to provide marine engines that are safe and have a reduced environmental impact, with the aim of achieving zero emissions in the Japanese shipping industry.
(*1) 4-cycle engine:
An engine in which the four basic processes of a reciprocating engine (intake, compression, combustion/expansion, and exhaust) are performed during two rotations of the crankshaft (the piston goes up and down two times, or four strokes). is. A wide range of output can be achieved by setting the piston bore diameter and rotation speed, and it is used for marine propulsion and power generation.

*Continuous output indicates the output at the end of the crankshaft. *The marine gear model shows our standard specifications, but it is also possible to support vertical non-core type and concentric type depending on the specification.
*Overload rate of 10% is limited to 1 continuous hour. *Engine mass includes the mass of Geislinger joints.
