Q1. 1. In CI engine, engine cooling work by coolent circulation in engine case, this coolent cool by radiator and coolent exchange heats of engine. 2 IC engine is which type engine in which in side of cylinder fule...

Ans.

CI engine uses coolant circulation for cooling, while IC engine is where fuel burns inside the cylinder.

CI engine cools through coolant circulation in engine case and radiator
IC engine is where fuel burns inside the cylinder
Coolant exchange helps in dissipating heat from the engine

Q2. What type of cooling tower is in your plant, water parameter for the same.

Ans.

The cooling tower in our plant is a crossflow cooling tower. The water parameters include pH level, conductivity, total dissolved solids (TDS), and temperature.

Our plant uses a crossflow cooling tower design, which allows for efficient heat transfer.
Water parameters monitored include pH level to ensure it is within the acceptable range for the system.
Conductivity of the water is measured to determine the level of dissolved solids present.
Total dissolved solids (TDS) are monit...read more

Q3. Can we run two motor from single vfd?how?

Ans.

Yes, it is possible to run two motors from a single VFD by using a special VFD with multiple motor control capability.

Use a VFD with multiple motor control capability to run two motors simultaneously.
Ensure that the VFD is rated for the combined load of both motors.
Connect the motors in parallel to the VFD output terminals.
Adjust the VFD settings to control the speed and direction of both motors independently.

Q4. How to work engine cooling in ci engine

Ans.

Engine cooling in CI engines is essential to maintain optimal operating temperatures and prevent overheating.

Ensure proper circulation of coolant throughout the engine
Regularly check coolant levels and quality
Monitor engine temperature using gauges
Clean and inspect radiator for any blockages
Consider using additives to improve cooling efficiency

Q5. What is ic engine

Ans.

An internal combustion engine (IC engine) is a heat engine where the combustion of fuel occurs inside the engine.

IC engines are commonly used in vehicles, generators, and other machinery.
They convert chemical energy into mechanical energy through combustion.
There are two main types of IC engines: spark-ignition engines (petrol engines) and compression-ignition engines (diesel engines).
