1 Engine Summary
The WinGD X62DF-S2.0 is a camshaftless, low-speed, reversible and rigidly di-
rect-coupled two-stroke engine. It features a low-pressure gas operation and a
common-rail injection system combined with the Intelligent Control by Exhaust
Recycling (iCER) system.
iCER operating
mode options
The WinGD X62DF-S2.0 is available in two variants:
• iCER gas mode
• iCER gas and diesel Tier III mode
The iCER gas mode improves the gas mode performance to significantly reduce
the emissions, especially methane emissions. Alternatively, the iCER gas and
diesel Tier III mode additionally provides Tier III compliance while operating in
diesel mode.

This chapter introduces the engine. It focuses on all aspects of the engine that
may be different from other engines. This chapter also highlights the suitability
of the engine.
1.1 Engine capability and features
This engine type is designed to run on fuel gas or on liquid fuel. The fuel gas is
evaporated Liquefied Natural Gas (LNG). The liquid fuel comprises a wide
range of marine fuels such as Marine Gas Oil (MGO) and Heavy Fuel Oil (HFO)
of varying qualities. This fuel flexibility is made possible by WinGD’s low-pres-
sure technology. The operating mode can be changed while the engine is running
without any loss of power.
Special characteristics of short-stroke dual-fuel engines
Designed to be smaller than other engines at this bore size, the short-stroke en-
gines have a reduced length and a reduced piston removal height, which is ideal
for engines with limited available installation space. Dual-fuel operation is the
most common application for the X-DF engines. This means that the engine can
either operate in gas or diesel mode. The operating mode can be changed while
the engine is running without any loss of power.
