Diesel Generating Set – 1.5 MWe / 50 Hz Wartsila Vasa 4R32 LN-E
This Wartsila diesel generating set has been used exclusively for
testing purposes by VTT Technical Research Centre of Finland and has
accumulated only 7,430 operating hours since new. Originally, it was
built as a conventional diesel engine capable of burning various heavy
fuels with viscosities of up to 730 cSt at 50°C. The engine was
subsequently upgraded by Wartsila to comply with the LN-E model
specification for their 32-series engines and it was equipped with
adequate fuel feeding systems, cylinder heads, pistons and liners for
dual fuel (DF) and gas diesel (GD) operation. The upgrade included the
installation of anti-polishing rings, an increase in engine output,
and the implementation of a completely new control system.
The unit has been used to test various fuels and components on behalf
of Wartsila. It has been exclusively serviced by Wartsila and remains
in good technical condition.
Over the years, Wartsila has installed new components and control
systems. At present, the engine is equipped to operate in three
different modes:
1. As a conventional diesel engine using heavy fuel oil (HFO);
2. As a Wartsila 32DF (Dual Fuel) engine using natural gas and light
diesel oil;
3. As a Wartsila GD (Gas Diesel) engine, where gas is compressed to
high pressure and injected into the cylinder, ignited by a pilot dose
of light diesel oil.
Naturally, to switch between modes, certain components—such as the
turbocharger, cylinder liners, pistons, and cylinder heads—must be
changed. The engine is currently configured for dual-fuel operation
(DF) with diesel-mode liners installed.
