Unit 152 Light vehicle engine, lubrication & cooling

Which system is specifically designed to reduce the friction between moving parts in a light vehicle engine?

• Cooling system

• Engine design

• Lubrication system

• Components and cycle of events

What is the primary focus of the cooling system in light vehicle maintenance?

• Enhancing fuel efficiency

• Reducing engine noise

• Managing engine temperature

• Increasing speed capabilities

What is the function of the engine block in a vehicle's engine?

• It controls the vehicle's speed.

• It houses the crankshaft, pistons, and connecting rods.

• It filters the engine oil.

• It cools the engine.

Where are the engine's valve gear components, including the camshaft/s, inlet and exhaust valves, located?

• In the sump

• In the engine block

• In the cylinder head

• Outside the engine

What is primarily located in the sump of an engine?

• The fuel injectors

• The lubrication components

• The cooling system

• The transmission gears

What material is typically used to make engine blocks?

• Steel

• Plastic

• Aluminium alloy or cast iron

• Carbon fiber

What is the characteristic of the liners in the wet liner engine configuration shown in the image?

• They are made of plastic.

• They are separate cast iron liners within the water coolant jackets.

• They are integrated into the engine block.

• They are made of aluminium.

What is the most common engine layout used in light vehicles, characterized by all cylinders being aligned in a single line?

• Vee

• Flat or Boxer

• Inline

• Transverse

Which engine layout is described as having a design that allows for a smaller bonnet line and is more compact?

• Inline

• Flat or Boxer

• Vee

• Rotary

What is a characteristic of the Flat or Boxer engine layout?

• High centre of gravity

• Requires a shorter bonnet than Vee engine

• Less expensive layout

• Low centre of gravity
