Hero MotoCorp Paint Shop Engineer Interview Questions and Answers

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

Poke yoke is a Japanese term for mistake-proofing. It is a technique used to prevent errors in manufacturing processes.

• Poke yoke involves designing a process or product in a way that makes it impossible to make a mistake.

• It can be achieved through the use of sensors, alarms, or physical barriers.

• Examples of poke yoke include car keys that can only be removed when the car is in park, or a phone charger that can only be ...read more
