What is the primary focus of the diesel engine 101 program's class four?

• Engine's electrical system

• Engine's lubrication system

• Fuel system

• Cooling system

Why is the lubrication system discussed before the fuel system?

• Because it's less important

• Because it's simpler and foundational for understanding hydraulics

• Because it powers the engine

• Because it's more complex

What can happen if there is a complete oil pressure loss?

• The engine might overheat

• The fuel system fails

• The engine shuts off

• The engine can be damaged within seconds

What are the three principles of oil in an engine?

• Lubricates, cools, and cleans the engine

• Filters, cools, and powers the engine

• Cools, cleans, and powers the engine

• Lubricates, powers, and filters the engine

What is the primary job of oil in an engine?

• To lubricate the engine

• To clean the engine

• To cool the engine

• To power the engine

Why are fluids considered non-compressible?

• Because they can be easily compressed

• Because they are solid

• Because their molecules are very far apart

• Because their molecules are close together and cannot be compressed into a smaller volume

What is a journal bearing?

• A type of oil filter

• A cooling system component

• A component that supports rotating parts in an engine

• A part of the fuel system

What is the role of the oil pump in the engine's lubrication system?

• To filter the oil

• To flow oil through the system

• To cool the oil

• To create oil pressure

What creates pressure in the engine's oil system?

• The oil pan

• Flow and restriction

• The fuel system

• The oil filter

What is the purpose of the oil cooler?

• To remove heat from the oil

• To pressurize the oil

• To filter the oil

• To lubricate the engine
