The document discusses an automatic governor system that uses a programmable logic controller (PLC) to regulate fuel supply to an engine based on varying load conditions. It describes how the PLC receives input from the engine through sensors and controls the fuel injection pump output accordingly. This allows the fuel to be adjusted as needed to maintain a consistent engine speed despite changing loads. The system provides benefits like reliability, efficiency and fuel savings compared to a traditional mechanical governor. Programming of PLCs is also described as relatively simple to learn.

2.  The function of a governor is to regulate the mean speed of
an engine, when there are variation in the load.
 when the load on an engine’s increase, its speed decreases,
therefore it becomes necessary to increase the supply of
working fluid. on the engine loaded increases, its speed
increases and thus less working fluid is required.
 The governor automatically controls the supply of working
fluid to the engine with the varying load conditions and keep
the mean speed within certain limits.

3.  Automatic Governor is a mechanical electronics device and its
used to control the fuel with variation of load as a governor.
 In this technique we are implemented the PLC those wire
will attached with the fuel pump and also second wire will
attached with the engine and it will give a massage to the
PLC.
 When the PLC receives a massage from the crank rotation
and forward the output to the FI Pump. FI pump maintain the
fuel as per requirement and also can save the unwanted fuel.

5.  When the load is applied on vehicle its also effected in an
engine so the input is given by the engine through a PLC
device those are attached with an engine.
 The output will shows in fuel indicator .through this indication
the F.I pump manage the fuel at a different stages. The help of
the PLC.
 it will work as a sensor which measures the fuel capacity As
the load.

7. 1.PROGRAMMABLE LOGIC CONTROLLE
 A PROGRAMMABLE LOGIC CONTROLLER (PLC) is an
industrial computer control system that continuously monitors
the state of input devices and makes decisions based upon a
custom program to control the state of output devices.
 Almost any production line, machine function, or process can
be greatly enhanced using this type of control system.
However, the biggest benefit in using a PLC is the ability to
change and replicate the operation or process while collecting
and communicating vital information.

9.  Programming of PLC is simple to learn. It’s not much
complicated.
 The controllers eliminated the need for rewiring and adding
additional hardware for each new configuration of logic.
 Automatic governors are also more cost-effective in the long
haul.
 Automatic governor are more reliable and more efficient,The
accuracy of the device also plays a pivotal role.

10.  A solenoid valve is an electro-mechanically operated valve,
The valve is controlled by an electric current through.
 solenoid in the case of a two-port valve the flow is switched
on or off, in the case of a three-port valve, the outflow is
switched between the two outlet ports.
 Solenoids offer fast and safe switching, high reliability, long
service life, good medium compatibility of the materials used,
low control power and compact design.

13.  24 V dc motor is used .
 12 V by the diode , transistor and resistance.

14.  Automatic governor are more reliable and more efficient . The
accuracy of the device also plays a pivotal role
 The electronic governor is also very versatile both in terms of
design and use. It reduces the installation time, and it also
delivers faster working.
 Automatic governor is maintenance free, because there are no
moving parts that may break or wear.
