Governor Parts and Mode of Operation
The engine is, as standard, provided with an elec-
tronic/mechanical type of fuel pump actuator of a
make approved by MAN Diesel.
The speed setting of the actuator is determined by
an electronic signal from the electronic governor
of a make approved by MAN Diesel. The actuator
shaft is connected to the fuel regulating shaft by
means of a mechanical linkage.
When selecting the governor, the complexity of
the installation has to be considered. We normally
distinguish between ‘conventional’ and ‘advanced’
marine installations.
The governor consists of the following elements:
• Actuator
• Revolution transmitter (pick-ups)
• Electronic governor panel
• Power supply unit
• Pressure transmitter for scavenge air.
The actuator, revolution transmitter and the pres-
sure transmitter are mounted on the engine.
The electronic governors must be tailor-made,
and the specific layout of the system must be mu-
tually agreed upon by the customer, the governor
supplier and the engine builder.
It should be noted that the shut down system, the
governor and the remote control system must be
compatible if an integrated solution is to be ob-
tained.
The minimum speed is 20-25% of the engines
nominal speed when an electronic governor is ap-
plied.
Governor for ‘Conventional’ plants
A typical example of a ‘conventional’ marine in-
stallation is:
• An engine directly coupled to a fixed pitch pro-
peller.
With a view to such an installation, the engine is,
as standard, equipped with a ‘conventional’ elec-
tronic governor with actuator of a make approved
by MAN Diesel, e.g.:
4 65 172 Lyngsø Marine
4 65 174 Kongsberg Maritime
4 65 175 Nabtesco
4 65 176 Mitsui Zosen Systems Research
4 65 177 Siemens.
As an option on engines without Power Take Off
(PTO), a mechanical-hydraulic type of governor is
available:
4 65 171 Woodward.
Governor for ‘Advanced’ plants
For more ‘advanced’ marine installations, such as,
for example:
• Plants with flexible coupling in the shafting sys-
tem
• Geared installations
• Plants with disengageable clutch for discon-
necting the propeller
• Plants with shaft generator with great require-
ment for frequency accuracy.
