Shaft power meter requirements
For all WinGD X-DF engines, the ECS requires the installation of a power meter
in the shaft line. This is to measure required parameters (see Table 1-7). The po-
sition of the shaft power meter is usually as close as possible to the main engine’s
flywheel. In the case of a PTO/PTI/PTH installation on the driving end side,
this means that the shaft power meter is usually installed between the PTO/PTI/
PTH and the main engine’s flywheel (see Figure 4-68,  4-114). Alternatively,
the mechanical power of the PTO must be calculated and transferred to the ECS
through the Propulsion Control System (PCS). This enables the ECS to deter-
mine the total mechanical power output of the engine, which is required for the
engine operation (see Figure 5-1,  5-1). The same calculation method must be
applied to a PTO installation on the free end side.

The iCER system
As part of the X-DF2.0 technology, this engine is equipped with the Intelligent
Control by Exhaust Recycling (iCER) system. While in gas mode, this allows for
the recirculation of part of the exhaust gas back to the engine. This replaces the
oxygen in the scavenge air inlet with CO
2
, resulting in an enhanced combustion
process.
The iCER system offers the following customer benefits:
• Reduced methane slip by up to 50 %
• Reduced energy consumption in gas mode
• Improved fuel consumption in diesel mode
Figure 1-6,  1-12 provides a schematic of the iCER system with one turbo-
charger.
