BMW Manufacturing Engineer Interview Questions, Process, and Tips

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

• Diesel engines use compression ignition, while petrol engines use spark ignition

• Diesel engines are more fuel efficient than petrol engines

• Diesel engines produce more torque at lower RPMs compared to petrol engines

• Petrol engines are generally quieter and smoother than diesel engines

• Diesel engines have a longer lifespan and are more durable t

Chassis is the structural framework of a vehicle, providing support and protection for the components mounted on it.

• Chassis is typically made of steel, aluminum, or composite materials.

• It includes the frame, suspension, steering system, and other structural components.

• The chassis determines the vehicle's overall strength, weight distribution, and handling characteristics.

Two-stroke engines have a power cycle completed in two strokes of the piston, while four-stroke engines have a power cycle completed in four strokes.

• Two-stroke engines have a simpler design with fewer moving parts compared to four-stroke engines.

• Two-stroke engines typically produce more power for their size but are less fuel-efficient than four-stroke engines.

• Four-stroke engines have separate intake, compression, power...read more

CNC machines are computer-controlled machines used for precision machining of various materials.

• CNC stands for Computer Numerical Control

• They are used in manufacturing processes to automate tasks such as cutting, drilling, milling, and more

• CNC machines follow instructions from CAD/CAM software to produce precise and complex parts

• Examples include CNC mills, lathes, routers, and plasma cutters

CNC machines are computer numerical control machines used for cutting and shaping materials, while DMC machines are direct metal deposition machines used for additive manufacturing.

• CNC machines are subtractive manufacturing machines, while DMC machines are additive manufacturing machines.

• CNC machines use computer numerical control to automate the cutting and shaping of materials, while DMC machines use a laser or elect...read more
