DE20DF / DE28DF / DE35DF
Further reducing the environmental impact of our engines we introduce our DF engine lineup: dual-fuel engines that switch seamlessly between gas and liquid fuel and, unlike a conventional diesel engine, can cut NOx by up to 80% during gas mode operation. This series brings together tried and tested technologies from our accredited diesel and gas lines into one economic solution.
- Complies with IMO NOx Tier3 exhaust emission regulations (in gas mode)
- Low-fuel consumption realized with lean combustion technology and optimum valve timing(variable valve timing-mechanism)
- Improved redundancies with the independent pilot fuel injection system, and peace of mind thanks to the Independent Safety System (ISS) fail-safe control
- Four-stage loading possible in gas mode (load response improvement)
*In the case of using DE28DF
- Supports various fuels (Oil:HFO/MDO/MGO, Gas:LNG)
Safety Features of the Engine's Gas Piping Area
- Double-walled gas piping system
- Ventilation function of first wall piping lines, and installed gas leak detection
- Instantaneous switching to diesel mode in the event of gas slip (failure of gas supply system), with injection of inert gas into the gas fuel pipe
