CIE Automotive Interview Questions, Process, and Tips

2-stroke engines have a power stroke every revolution, while 4-stroke engines have a power stroke every other revolution.

• 2-stroke engines are simpler and lighter than 4-stroke engines.

• 2-stroke engines have a higher power-to-weight ratio than 4-stroke engines.

• 2-stroke engines require a mixture of oil and fuel, while 4-stroke engines have separate oil and fuel systems.

• 4-stroke engines are more fuel-efficient and produce ...read more

The least count of a Vernier caliper is typically 0.1 mm or 0.02 mm.

• The least count is the smallest measurement that can be read on the scale of the caliper.

• It depends on the design and precision of the caliper.

• For example, a standard Vernier caliper may have a least count of 0.1 mm, while a digital caliper may have a least count of 0.02 mm.

A centrifugal pump is a mechanical device that uses centrifugal force to move fluids through a piping system.

• It works by converting rotational kinetic energy into hydrodynamic energy.

• Fluid enters the pump through the center of a rotating impeller and is flung outward by centrifugal force.

• The fluid then exits the pump through a discharge nozzle.

• Centrifugal pumps are commonly used in industries such as oil and gas, chemi...read more

Petrol engines use spark ignition while diesel engines use compression ignition.

• Petrol engines use a spark plug to ignite the fuel-air mixture while diesel engines compress the air to a high temperature and pressure to ignite the fuel.

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

• Petrol engines are lighter and quieter while diesel engines are...read more

Screw gauge is a measuring instrument used to measure the diameter of a wire or thickness of a sheet.

• Also known as micrometer screw gauge

• Consists of a U-shaped frame with a screw mechanism

• The screw has a calibrated scale and a thimble for precise measurement

• Used in industries like manufacturing, engineering, and metalworking

• Example: Used to measure the thickness of a sheet of metal in a factory

My favorite subject is Mathematics.

Vernier Caliper and Micrometer least count

• Least count of Vernier Caliper is 0.02 mm and Micrometer is 0.01 mm

• Least count is the smallest measurement that can be read on the instrument

• Vernier Caliper is used to measure length, diameter, depth, and thickness

• Micrometer is used to measure small distances, thickness, and diameters
