ILJIN AUTOMOTIVE Diploma Trainee Engineer Interview Questions, Process, and Tips

An engine is a machine that converts fuel into mechanical energy to power vehicles or machinery.

• Engines work by burning fuel to create heat energy, which is then converted into mechanical energy to move pistons or turbines.

• There are different types of engines such as internal combustion engines, steam engines, and electric motors.

• The four-stroke cycle is commonly used in internal combustion engines, where intake, compr...read more

There are two main types of braking systems: mechanical and hydraulic.

• Mechanical braking system uses friction to slow down or stop a vehicle, such as drum brakes or disc brakes.

• Hydraulic braking system uses fluid pressure to transfer force from the brake pedal to the brake pads, such as in hydraulic disc brakes.

• Other types of braking systems include regenerative braking used in electric vehicles and anti-lock braking s

Four-stroke engines have four stages (intake, compression, power, exhaust) per cycle, while two-stroke engines have only two stages (compression, power).

• Four-stroke engines have separate intake and exhaust strokes, while two-stroke engines combine intake and exhaust in one stroke.

• Four-stroke engines are more fuel efficient and produce less pollution than two-stroke engines.

• Examples of four-stroke engines include most c...read more

CC of Engine refers to the engine displacement in cubic centimeters, indicating the total volume of all the cylinders in the engine.

• CC stands for cubic centimeters

• It is a measurement of engine displacement

• Higher CC generally means more power and torque

• For example, a 1500cc engine has a displacement of 1500 cubic centimeters

An engine is a machine that converts fuel into mechanical energy to produce motion.

• An engine typically consists of cylinders, pistons, valves, and a crankshaft.

• There are different types of engines such as internal combustion engines, steam engines, and electric motors.

• Engines are used in vehicles, power plants, and various machinery to generate power.

• Examples include gasoline engines in cars, diesel engines in trucks,

My favourite job is one that challenges me to think creatively and problem-solve on a daily basis.

• I enjoy jobs that allow me to work with a team towards a common goal

• I thrive in fast-paced environments where I can continuously learn and grow

• I appreciate jobs that offer opportunities for innovation and thinking outside the box

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

• Stress is a measure of the internal forces within a material, typically caused by external loads.

• Strain is the measure of how much a material deforms or changes shape in response to stress.

• Stress is usually expressed in units of force per unit area (such as N/m^2 or Pa), while strain is dimensionless.

• Stress can be te...read more

A mechanical engineer is a professional who designs, develops, and tests mechanical systems and devices.

• Designing and analyzing mechanical systems

• Developing prototypes and testing them for functionality

• Collaborating with other engineers and professionals to ensure project success

• Applying principles of physics and materials science to solve engineering problems

Heating process is the method of increasing the temperature of a substance using external energy sources.

• Heating process involves transferring energy to a material to raise its temperature.

• Common methods of heating include conduction, convection, and radiation.

• Examples include heating water on a stove, using a microwave to heat food, and using a furnace to heat a room.

Drawing is a freehand representation of an object, while drafting involves using tools and instruments to create precise technical drawings.

• Drawing is typically done by hand, using pencils, pens, or other artistic tools.

• Drafting involves using tools like T-squares, triangles, and drafting machines to create accurate technical drawings.

• Drawings are often more artistic and expressive, while drafts are more technical and ...read more

Design in mechanical engineering involves creating and developing products, machines, systems, or structures to meet specific requirements.

• Designing involves conceptualizing, planning, and creating blueprints for mechanical components or systems.

• Considerations include functionality, efficiency, safety, cost, and aesthetics.

• Designers use software like CAD (Computer-Aided Design) to create detailed models and simulations...read more

PV diagram is a graphical representation of the pressure-volume relationship in thermodynamics.

• PV = nRT is the ideal gas law formula where P is pressure, V is volume, n is number of moles, R is the gas constant, and T is temperature.

• Work done in a PV diagram is given by the area under the curve.

• PV diagrams are commonly used in analyzing thermodynamic processes such as isothermal, adiabatic, isobaric, and isochoric proc

Automobile refers to a vehicle designed for transportation, typically powered by an internal combustion engine.

• Automobiles are commonly used for personal transportation, as well as for commercial purposes.

• They come in various types such as cars, trucks, buses, and motorcycles.

• Automobiles have revolutionized transportation and have greatly impacted society and economy.

• Examples of automobile manufacturers include Ford, T

Diesel engines use compression ignition while petrol engines use spark ignition.

• Diesel engines compress air to ignite fuel, while petrol engines use spark plugs

• Diesel engines are more fuel efficient but produce more emissions

• Petrol engines are quieter and smoother than diesel engines

• Diesel engines are commonly used in trucks and heavy machinery, while petrol engines are used in cars and motorcycles

The least count of a Vernier caliper is 0.02 mm and the least count of a micrometer is 0.01 mm.

• Vernier caliper has a least count of 0.02 mm, which means it can measure up to 0.02 mm accuracy.

• Micrometer has a least count of 0.01 mm, allowing for measurements with 0.01 mm precision.

Subtracting 3.45 from 9.23 gives the result of 5.78.

• Subtract the second number from the first number

• 9.23 - 3.45 = 5.78
