Automotive Manufacturers Diploma Mechanical Engineer Interview Questions and Answers

The question is asking for the candidate's name and address.

• Provide your full name and complete address.

• Include your street name, city, state, and zip code.

• Ensure the address is accurate and up to date.

A two-stroke engine completes a power cycle in two strokes of the piston, while a four-stroke engine completes 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 but lower fuel efficiency compared to four-stroke engines.

• Four-stroke engines have separate intake, compression, power, and exhaust strokes, while two-stro...read more

A pictorial representation of a SI engine with valve opening, TDC, and BDC.

• SI engine stands for Spark Ignition engine, which is commonly used in gasoline-powered vehicles.

• Valve opening refers to the movement of the intake and exhaust valves to allow fuel-air mixture in and exhaust gases out of the combustion chamber.

• TDC (Top Dead Center) is the position of the piston at the extreme top of its stroke.

• BDC (Bottom Dead Ce...read more

I would improve the fuel efficiency of TVS motorcycles by implementing advanced engine technology.

• Implementing electronic fuel injection system for better fuel management

• Introducing hybrid technology for improved mileage

• Optimizing aerodynamics of the motorcycle for reduced drag

• Using lightweight materials for better fuel economy

I am a dedicated production engineer with a strong background in manufacturing processes and quality control.

• Graduated with a degree in Mechanical Engineering

• Experience working in a manufacturing plant for 3 years

• Proficient in CAD software for designing production layouts

• Implemented lean manufacturing principles to improve efficiency

• Led a team in reducing production downtime by 20%

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
