T.v. Sundram Iyengar & Sons Diploma Mechanical Engineer Interview Questions and Answers

Automobile refers to a vehicle designed for transportation, typically powered by an internal combustion engine.

• Automobiles are commonly used for personal transportation, as well as for commercial purposes.

• They come in various types such as cars, trucks, buses, and motorcycles.

• Automobiles have revolutionized transportation and have greatly impacted society and economy.

• Examples of automobile manufacturers include Ford, T

Diesel engines use compression ignition while petrol engines use spark ignition.

• Diesel engines compress air to ignite fuel, while petrol engines use spark plugs

• Diesel engines are more fuel efficient but produce more emissions

• Petrol engines are quieter and smoother than diesel engines

• Diesel engines are commonly used in trucks and heavy machinery, while petrol engines are used in cars and motorcycles

The least count of a Vernier caliper is 0.02 mm and the least count of a micrometer is 0.01 mm.

• Vernier caliper has a least count of 0.02 mm, which means it can measure up to 0.02 mm accuracy.

• Micrometer has a least count of 0.01 mm, allowing for measurements with 0.01 mm precision.

Subtracting 3.45 from 9.23 gives the result of 5.78.

• Subtract the second number from the first number

• 9.23 - 3.45 = 5.78

The types of materials used in engines vary depending on the specific engine type and its components.

• Engines can be made of various materials such as cast iron, aluminum, steel, and alloys.

• Different engine parts may require different materials, for example, pistons are often made of aluminum alloy.

• Engine components like cylinder heads, crankshafts, and connecting rods can be made of cast iron or steel.

• Some engines may ...read more

Four-stroke engines have four stages (intake, compression, power, exhaust) per cycle, while two-stroke engines have only two stages (compression, power).

• Four-stroke engines have separate intake and exhaust strokes, while two-stroke engines combine intake and exhaust in one stroke.

• Four-stroke engines are more fuel efficient and produce less pollution than two-stroke engines.

• Examples of four-stroke engines include most c...read more

CC of Engine refers to the engine displacement in cubic centimeters, indicating the total volume of all the cylinders in the engine.

• CC stands for cubic centimeters

• It is a measurement of engine displacement

• Higher CC generally means more power and torque

• For example, a 1500cc engine has a displacement of 1500 cubic centimeters

An engine is a machine that converts fuel into mechanical energy to produce motion.

• An engine typically consists of cylinders, pistons, valves, and a crankshaft.

• There are different types of engines such as internal combustion engines, steam engines, and electric motors.

• Engines are used in vehicles, power plants, and various machinery to generate power.

• Examples include gasoline engines in cars, diesel engines in trucks,
