Eicher Motors Diploma Trainee Engineer Interview Questions and Answers

Q1. Difference Between Four & Two Stroke Engine ?
Ans. 
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

Q2. What is the CC of Engine ?
Ans. 
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

Q1. What is stress or strain
Ans. 
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
