17. Fuel System
17.1
General
The Wärtsilä
®
32 engine is designed for continuous Light, Heavy
or Crude Oil duty. The fuel feed system pressure adjustment
recommendations varies depending on fuel quality and installa-
tion and the values mentioned in this chapter should be used as
guidelines only.
As the fuel treatment system plan usually varies from one
installation to another, the system described in this manual may
not exactly correspond to the actual installation. See installation
specific documentation for further information.
The engine can be started and stopped on heavy fuel or crude
oil provided that the fuel is heated to operating temperature, see
recommended operating data in section 17.4.4 and chapter 01.
Note!
It is of great importance that the fuel treatment before the
engine is done properly i.e. necessary filter maintenance is
carried out according to schedule. The efficiency of the fuel
filtration influences directly on the injection equipment lifetime
and thus on the engine performance.
17.1.1 Functional description
The fuel is pressurized by the pump (13) and filtered by the filter
(6), see Fig 17-1. The pressure control valve (15) maintains correct
pressure in the system and valve (3) at each engine.
Fuel feed pressure and temperature sensors are located on the
engine inlet piping and monitored on the LDU panel on the engine
as well as in the engine control room.
Fuel leaking from injection pumps and injection valves is col-
lected (103) in a separate enclosed system. This fuel can be reused.
A separate pipe system leading from the top level of the engine
block collects waste oil, fuel and water arising, for example, when
overhauling cylinder heads.
The high pressure system, with injection pumps and injection
valves, is described in chapter 16.
Fuel feed and circulating unit
In the fuel feed unit (A), see Fig 17-1, the fuel is pressurized in
order to avoid disturbances due to vaporising of water and fuel.
The fuel-circulating unit (B) maintains de-aerated fuel of correct
viscosity (correct temperature) and pressure to the engine/en-
gines (C) and circulates the fuel in the main system.
