Nipman Fastener Industries Interview Questions and Answers

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

• Diesel engines use compression ignition, where the fuel-air mixture is compressed until it spontaneously ignites.

• Petrol engines use spark ignition, where a spark plug ignites the fuel-air mixture.

• Diesel engines are more fuel efficient than petrol engines.

• Petrol engines generally have higher power output compared to diesel engines.

• Diesel eng...read more

OEE can be calculated by multiplying Availability, Performance, and Quality.

• Calculate Availability: (Operating Time - Downtime) / Operating Time

• Calculate Performance: (Ideal Cycle Time * Total Count) / Operating Time

• Calculate Quality: Good Count / Total Count

• Multiply Availability, Performance, and Quality to get OEE

• Example: Availability = (400 - 50) / 400 = 0.875, Performance = (2 * 350) / 400 = 1.75, Quality = 300 / 3
