HWASHIN Automotive Production Engineer Interview Questions and Answers for Experienced

There are two main types of brakes: disc brakes and drum brakes.

• Disc brakes use calipers to squeeze brake pads against a rotor to slow down the vehicle.

• Drum brakes use brake shoes that press against the inside of a drum to slow down the vehicle.

To work a piston, it must be properly lubricated and connected to a crankshaft to convert linear motion into rotational motion.

• Ensure the piston is properly lubricated to reduce friction and wear

• Connect the piston to a crankshaft to convert linear motion into rotational motion

• Monitor piston movement for any abnormalities or malfunctions

There are two main types of engines: internal combustion engines and external combustion engines.

• Internal combustion engines: gasoline engines, diesel engines

• External combustion engines: steam engines

• Other types include rotary engines, electric engines, etc.

2 stroke engines are more powerful than 4 stroke engines due to their higher power-to-weight ratio and faster combustion process.

• 2 stroke engines have a power stroke for every revolution of the crankshaft, while 4 stroke engines have a power stroke every other revolution.

• 2 stroke engines have a simpler design with fewer moving parts, leading to less friction and more efficient power output.

• 2 stroke engines have a faste...read more
