Tata Motors Apprenticeship Trainee Interview Questions and Answers

The firing order of a 6-cylinder engine is different from that of a 4-cylinder engine.

• The firing order determines the sequence in which the cylinders ignite their fuel-air mixture.

• In a 6-cylinder engine, the firing order can vary depending on the engine design.

• A common firing order for a 6-cylinder engine is 1-5-3-6-2-4.

• In a 4-cylinder engine, the firing order is typically 1-3-4-2.

A diesel generator works by converting diesel fuel into mechanical energy which is then converted into electrical energy.

• Diesel fuel is injected into the combustion chamber where it ignites and creates high pressure gases that push the piston down, creating mechanical energy.

• The mechanical energy is then converted into electrical energy through the use of an alternator.

• The alternator uses a magnetic field and a conduct...read more

A diesel engine works by compressing air in the cylinder, which heats up and ignites the fuel injected into the cylinder.

• Air is drawn into the cylinder and compressed by the piston

• The compressed air heats up and ignites the fuel injected into the cylinder

• The explosion pushes the piston down, which turns the crankshaft and powers the engine

• Diesel engines are more efficient than gasoline engines because they compress the...read more

A train doesn't need a differential because its wheels are fixed to the same axle and rotate at the same speed.

• Train wheels are fixed to the same axle

• Wheels rotate at the same speed

• Differential is used in vehicles with wheels that rotate at different speeds

• Differential allows for smooth turning

Petrol engines have lower compression ratios compared to diesel engines.

• Petrol engines have lower compression ratios to prevent knocking or detonation.

• Diesel engines have higher compression ratios to ignite the fuel without spark plugs.

• Higher compression ratios in diesel engines result in better fuel efficiency and torque.

• Petrol engines require lower compression ratios to accommodate the lower octane rating of petrol f...read more

Electric motor production started in the late 19th century and has since evolved with advancements in technology.

• Electric motor production began in the late 19th century.

• The first practical electric motor was developed by Thomas Davenport in 1834.

• Advancements in technology have led to the development of more efficient and powerful electric motors.

• Electric motor production has grown significantly with the rise of electr
