Hyundai Motor India Limited Diploma Mechanical Engineer Interview Questions, Process, and Tips

There are two types of manifolds: intake manifold and exhaust manifold.

• Intake manifold: It supplies the air-fuel mixture to the cylinders.

• Exhaust manifold: It collects and expels the exhaust gases from the cylinders.

• Examples: Cast iron and stainless steel manifolds.

Oil pan gaskets are typically made from materials such as rubber, cork, silicone, or a combination of these.

• Rubber is a common material used in oil pan gaskets due to its flexibility and resistance to oil and heat.

• Cork is another material used in gaskets as it provides a good seal and is resistant to oil and chemicals.

• Silicone gaskets are known for their durability and ability to withstand high temperatures.

• Some gasket...read more

There are several types of manifold gaskets used in automobile engines.

• Exhaust manifold gaskets

• Intake manifold gaskets

• Throttle body gaskets

• EGR (Exhaust Gas Recirculation) gaskets

• Turbocharger gaskets

• Supercharger gaskets

Yes, the flywheel is used as a part of a mechanism.

• The flywheel is a mechanical device used to store rotational energy.

• It is typically used in engines to maintain a steady rotational speed and provide smooth power delivery.

• In automobiles, the flywheel is connected to the crankshaft and helps in starting the engine, storing energy during deceleration, and providing rotational inertia.

• It also helps in reducing engine vib...read more

There are two types of air cleaners: mechanical air cleaners and electronic air cleaners.

• Mechanical air cleaners use filters to trap dust and other particles from the air.

• Electronic air cleaners use an electric charge to attract and trap particles.

• Examples of mechanical air cleaners include panel filters, pleated filters, and HEPA filters.

• Examples of electronic air cleaners include electrostatic precipitators and ioniz

Pump gaskets are made of various materials.

• Pump gaskets can be made of rubber, cork, paper, or metal.

• Rubber gaskets are commonly used due to their flexibility and resistance to fluids.

• Cork gaskets are known for their compressibility and ability to seal irregular surfaces.

• Paper gaskets are used in low-pressure applications.

• Metal gaskets, such as those made of steel or copper, are used in high-temperature and high-pressu

Felix Wankel, a German engineer, originated the Wankel engine.

• The Wankel engine was invented by Felix Wankel in the 1950s.

• Felix Wankel was a German mechanical engineer.

• The Wankel engine is a type of internal combustion engine that uses a rotary design.

• It is known for its compact size, high power-to-weight ratio, and smooth operation.

• Mazda is one of the most well-known manufacturers to have used the Wankel engine in the

The Wankel engine was originated in Germany.

• The Wankel engine was invented by Felix Wankel in the 1950s.

• It was first developed and produced by the German company NSU Motorenwerke AG.

• The engine design features a rotary combustion chamber instead of the traditional reciprocating pistons.

• It offers advantages such as compact size, high power-to-weight ratio, and smooth operation.

• Mazda is one of the most well-known manufact...read more

There are various types of engines based on the number of cylinders.

• Engines can have 1, 2, 3, 4, 5, 6, 8, 10, 12, or even more cylinders.

• The number of cylinders affects the engine's performance, power, and fuel efficiency.

• Examples include inline engines (4-cylinder), V engines (6-cylinder), and W engines (12-cylinder).

There are two kinds of two-stroke engines: spark ignition and compression ignition.

• Spark ignition two-stroke engines: These engines use a spark plug to ignite the fuel-air mixture, commonly found in motorcycles, chainsaws, and outboard motors.

• Compression ignition two-stroke engines: These engines rely on the heat generated by compression to ignite the fuel-air mixture, commonly found in large marine engines and some in

4 stroke engine is classified as an internal combustion engine.

• It has four strokes: intake, compression, combustion, and exhaust.

• It is commonly used in automobiles, motorcycles, and small aircraft.

• It is more fuel-efficient and produces less pollution than a 2-stroke engine.

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
