Vedanta Aluminium Engineer Interview Questions and Answers

Differential is a mechanical device that allows the wheels of a vehicle to rotate at different speeds.

• Differential is commonly found in vehicles with multiple wheels, such as cars and trucks.

• It is located in the center of the axle and connects the drive shaft to the wheels.

• The main purpose of a differential is to allow the wheels to rotate at different speeds while still receiving power from the engine.

• This is importan...read more

EGR system stands for Exhaust Gas Recirculation system. It is used in internal combustion engines to reduce nitrogen oxide emissions.

• EGR system recirculates a portion of exhaust gases back into the engine's intake manifold.

• This reduces the combustion temperature and lowers the production of nitrogen oxides.

• The recirculated exhaust gases also help in reducing engine knocking and improving fuel efficiency.

• EGR systems can...read more

The I-shift automatic gearbox uses helical gears and spur gears.

• I-shift automatic gearbox uses helical gears for the main transmission and spur gears for the auxiliary section

• Helical gears provide smoother and quieter operation compared to spur gears

• Spur gears are used for the auxiliary section as they are more efficient for high torque applications

The firing order in a 6 cylinder engine refers to the sequence in which each cylinder fires.

• The firing order is determined by the engine design and is usually specified by the manufacturer.

• It is important to follow the correct firing order to ensure proper engine performance and minimize vibrations.

• The firing order can be found in the engine's service manual or by contacting the manufacturer.

• For example, a common firin

RPM turbo refers to the revolutions per minute of a turbocharger, which measures how fast the turbocharger's turbine is spinning.

• RPM turbo is a measure of the speed at which a turbocharger's turbine is rotating

• It indicates the efficiency and power output of the turbocharger

• Higher RPM turbo values generally result in increased boost pressure and engine performance

• For example, a turbo with an RPM turbo of 10,000 would sp
