Bridge Control of Main Engine 
Bridge control of Main Engines:
Automatic control of the starting of the main engine can be done from the bridge as well as in Engine control room. The automatic controls employed in starting the engine is by the following sequence:- Automatic control used in correctly positioning of the cam shaft.
- Admitting starting air
- Admitting fuel
- Starting air shut off
- Speed adjustment to the value required
Thus the engine is started and the various parameters like temperature, pressure, flow and tank level have to measured at every watch to make sure that the engine is running safely.
Temperatures of lube oil, JCW, exhaust gas, etc. are measured.
Pressures of lube oil, JCW, fuel oil, and starting air etc. are measured.
Flow of fuel oil is measured while running.
Tank levels of Heavy fuel oil, diesel oil, and lube oil are measured.
For measuring the parameters we make use of the transducers, in turn sending the input signal to the automatic control system. |
