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

Two stroke engine completes a power cycle in one revolution of the crankshaft while four stroke engine completes it in two revolutions.

• Two stroke engine has no valves and uses ports to let in air and fuel mixture and expel exhaust gases.

• Four stroke engine has separate intake, compression, power, and exhaust strokes.

• Two stroke engine is simpler and lighter but less efficient and more polluting than four stroke engine.

Lubrication reduces friction and wear between two surfaces in contact with each other.

• Reduces friction and wear between two surfaces

• Prevents overheating and damage to the machinery

• Improves efficiency and performance of the machinery

• Types of lubricants include oil, grease, and dry lubricants

• Lubrication systems include splash, pressure, and circulating systems

CFMEA stands for Control Failure Mode and Effects Analysis.

• CFMEA is a systematic approach used to identify and mitigate potential failures in a process or system.

• It involves analyzing failure modes, their causes, and the potential effects on the process or system.

• CFMEA helps in prioritizing and implementing control measures to prevent or minimize failures.

• It is commonly used in industries such as manufacturing, automot...read more

System level DFMEA is given main preference.

• System level DFMEA considers the entire system and its interactions.

• Component level DFMEA focuses on individual components.

• System level DFMEA is more comprehensive and effective in identifying potential failures.

• Example: In automotive industry, system level DFMEA would consider the entire vehicle and its subsystems.

• Example: In medical devices, system level DFMEA would conside...read more

G-codes are used in CNC machines to control the movement of the cutting tool. Here are 5 commonly used G-codes.

• G00 - Rapid positioning

• G01 - Linear interpolation

• G02 - Circular interpolation (clockwise)

• G03 - Circular interpolation (counterclockwise)

• G28 - Return to home position

IC engine stands for Internal Combustion engine. It is a heat engine that converts chemical energy into mechanical energy.

• IC engine is used in automobiles, generators, and other machinery.

• It works by burning fuel inside a combustion chamber to create high-pressure gases that move a piston.

• Examples of IC engines include gasoline engines, diesel engines, and natural gas engines.
