Trident Group Shift Maintenance Engineer Interview Questions and Answers

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).

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

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
