The Engine Block Quiz

What is the main function of the engine block?

• To house the cylinders and provide passageways for coolant and oil

• To provide a smooth surface for the pistons to slide on

• To house the alternator and water pump

• To regulate the oil pressure

What are engine blocks usually made of?

• Steel or copper

• Titanium or carbon fiber

• Cast iron or cast aluminum alloy

• Plastic or rubber

What is the purpose of the oil passageways inside the engine block?

• To supply oil to various parts of the engine

• To cool down the engine during combustion

• To regulate the engine temperature

• To provide a smooth surface for the pistons

Which components are generally mounted to the engine block?

• Alternator, water pump, starter motor, AC compressor

• Radiator, fuel pump, exhaust manifold, turbocharger

• Transmission, drive shaft, differential, axle

• Brake caliper, brake rotor, brake pad, brake drum

What is the primary reason for using aluminum alloy for engine blocks?

• To reduce the cost of manufacturing

• To achieve fuel economy and performance

• To increase the weight of the engine

• To make the engine block more durable

What is the purpose of the crosshatch pattern inside a cylinder?

• To prevent the piston rings from contacting the cylinder wall

• To reduce the amount of oil needed for lubrication

• To increase the compression ratio of the engine

• To provide a grip for the oil and minimise friction

What is the function of the 'face' on the engine block?

• To form a seal with the cylinder head and create the combustion chamber

• To regulate the flow of coolant and oil

• To support the weight of the engine accessories

• To provide a smooth surface for the pistons

What is the main purpose of the oil galleries inside the engine block?

• To supply oil to the rest of the engine

• To cool down the engine during combustion

• To regulate the engine temperature

• To provide a smooth surface for the pistons

What is the role of the core plugs in the engine block?

• To provide a smooth surface for the pistons

• To seal the holes used to remove sand during the casting process

• To regulate the flow of coolant and oil

• To pop out if the cooling water freezes

What is the purpose of the main caps in the engine block?

• To provide a smooth surface for the pistons

• To clamp the crankshaft into the saddles and hold the bearings

• To support the weight of the engine accessories

• To regulate the flow of coolant and oil
