Dual Fuel Engine (DE28DF/DE35DF)

Product catalog summary

Overview: Daihatsu Diesel has developed dual-fuel engines, DE28DF and DE35DF, which can operate on both liquid and gas fuels. These engines are designed to reduce environmental impact by lowering NOx emissions by 80% when using gas fuel. The development is part of a project supported by the Ministry of Land, Infrastructure, Transport and Tourism and Nippon Kaiji Kyokai (ClassNK).

Specifications: The engines comply with IMO NOx Tier III emissions regulations when operating on gas fuel and adhere to the IGF Code for LNG Tank and Fuel Gas Supply Systems. They offer high fuel efficiency through lean combustion technology and optimized valve timing. The engines can switch between liquid and gas fuels based on fuel prices and availability.

Fuel System: The LNG fuel tank features a vacuum double shell with pressure resistance up to -163ºC/10 bar. It has a low boil-off rate and can handle changes in load, liquid level, and LNG characteristics. The tank has a capacity of 27m3, with a usable range of approximately 22m3, allowing for 38 hours of operation at full load.

Safety Features: The system includes a gas leakage detector and a main gas fuel valve that cuts off gas flow during leaks or ventilation failures. Double-layer piping or ducts are used to ensure safety, with options for inert gas charging or ventilation with exhaust fans.

Engine Models: The DE28DF and DE35DF engines come in various configurations, with outputs ranging from 1,730 kW to 4,080 kW. They are compatible with natural gas, MDO, and HFO fuels and have been type-approved for use.

Applications: These engines are suitable for marine vessels and can be retrofitted to existing systems. They offer automatic switching for smooth operation between different fuel modes.
