10+ Oprating Engineer Interview Questions and Answers for Freshers

Two stroke engines complete a power cycle in two strokes of the piston, while four stroke engines complete it in four strokes.

• Two stroke engines have a simpler design and are lighter than four stroke engines.

• Two stroke engines have a higher power-to-weight ratio than four stroke engines.

• Four stroke engines are more fuel efficient and have a longer lifespan than two stroke engines.

• Examples of two stroke engines include chainsaws, dirt bikes, and jet skis, while examples of fou...read more

Petrol engine and diesel engine are two types of internal combustion engines that differ in their fuel ignition process.

• Petrol engines use spark plugs to ignite the fuel-air mixture, while diesel engines use compression to ignite the fuel

• Petrol engines are generally more powerful and responsive, while diesel engines are more fuel-efficient and have more torque

• Examples of petrol engines include those found in cars, motorcycles, and small aircraft, while diesel engines are comm...read more

I would prefer to travel by train if available for a more comfortable and efficient journey to the office.

• I would choose to travel by train if it is available as it is usually faster and more comfortable than a bus.

• Taking the train can also be more reliable in terms of arrival time compared to buses which may be affected by traffic.

• Trains often have amenities such as restrooms and food services which can make the journey more convenient.

• If the train is not available or the sc...read more

Types of mechanical industrial belts include V-belts, timing belts, flat belts, and ribbed belts.

• V-belts: commonly used for power transmission in industrial machinery

• Timing belts: used in engines to synchronize the rotation of the crankshaft and camshaft

• Flat belts: used for conveying materials in industrial applications

• Ribbed belts: have longitudinal ribs on the inner side for better grip and reduced slippage

There are several types of shafts including straight, stepped, tapered, splined, and flexible.

• Straight shafts are the most common type and have a uniform diameter throughout their length.

• Stepped shafts have varying diameters at different sections.

• Tapered shafts have a gradually decreasing diameter from one end to the other.

• Splined shafts have ridges or teeth along their length to connect with other components.

• Flexible shafts are used in applications where a rigid shaft cannot...read more

A drill machine works by rotating a drill bit to create holes in various materials.

• Drill machines use a motor to rotate the drill bit at high speeds.

• The drill bit is pressed against the material being drilled, creating a hole.

• Different types of drill bits are used for different materials, such as wood, metal, or concrete.

A damper is a device that reduces or controls the flow of air, gas, or liquid.

• Used in HVAC systems to regulate airflow

• Can be manually or automatically controlled

• Examples include fire dampers, smoke dampers, and volume dampers

Types of gears include spur gears, helical gears, bevel gears, worm gears, rack and pinion gears, and planetary gears.

• Spur gears have straight teeth and are the most common type of gear.

• Helical gears have angled teeth for smoother and quieter operation.

• Bevel gears have cone-shaped teeth and are used to change the direction of rotation.

• Worm gears have a screw-like appearance and provide high gear reduction ratios.

• Rack and pinion gears convert rotational motion into linear moti...read more
