An eight cylinder engine with two banks of four cyclinders.

Question 5

Internal Combustion Engine

Answer 5

An engine that generates mechanical energy/motion throught the burning of fuel and air.

Question 6

Combustion Chamber

Answer 6

A space within an engine head where fuel is burned to create energy.

Question 7

Combustion

Answer 7

A chemical reaction that occurs when a substance reacts rapidly with oxygen, releasing energy in the form of heat.

Question 8

Piston

Answer 8

A cylindrical metal component that moves up and down inside an engine cylinder.

Question 9

Cylinder

Answer 9

A cylindrical chamber/tube containing pistons and connecting rods.

Question 10

Four Stroke Cycle

Answer 10

A process that involves four unique strokes of a piston creating a cycle that converts fuel into mechanical energy.

Question 11

The Four Strokes

Answer 11

Intake, Compression, Combustion, and Exhaust.

Question 12

Intake Stroke

Answer 12

The piston descends, sucking an air fuel mixture into the cylinder through the intake port.

Question 13

Compression Stroke

Answer 13

The piston ascends with all valves closed, compressing the fuel air mixture, increasing it’s pressure.

Question 14

Combustion Stroke

Answer 14

The spark plug ignites the compressed air fuel mixture, creating an explosion that pushes the piston downward.

Question 15

Exhaust Stroke

Answer 15

The piston ascends with the exhaust valves open, allowing the burnt gasses to exit the cylinder.

Question 16

Valves

Answer 16

Components that control the flow of air fuel mixtures into a combustion chamer, and gasses out from a combustion chamber.

Question 17

Engine Block

Answer 17

The main structure of an engine that houses all of it’s components.

Question 18

Engine Head/Cylinder Head

Answer 18

A structure that sits on the cylinders, forming the roof of combustion chambers.

Question 19

Which components are housed within the engine head?

Answer 19

Combustion chambers, valves, and spark plugs.

Question 20

Which components are housed within the engine block?

Answer 20

Cylinders, pistons, connecting rods, crankshaft, and sometimes the camshaft.

Question 21

Crankshaft

Answer 21

A component that converts the pumping motion of a piston into rotational or spinning motion.

Question 22

Balancing Lobes/Counterweights

Answer 22

Lobes that attach to the crankshaft to balance the forces produced by the pistons and connecting rods.

Question 23

Oil Seal

Answer 23

A seal that prevents leaks where a crankshaft extends through a block.

Question 24

Bearing Surface

Answer 24

The surface of the bearing that interacts directly with the moving component it supports.

Question 25

Oil Filter

Answer 25

A device that removes contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil.

Question 26

Lubrication Holes

Answer 26

Part of a system of oil passages that feed oil to the crankshaft's bearings and connecting rods.

Question 27

Oil Passages

Answer 27

Channels within the engine block, crankshaft, camshaft, and other components through which oil flows.

Question 28

Oil Pan

Answer 28

A pan which a crankshaft is fitted into, and holds oil for a car's engine.

Question 29

Crankcase

Answer 29

The area inside the oil pan.

Question 30

Oil Pump

Answer 30

A component in the oil pan that pressurizes/pushes oil and sends it through the engine.

Question 31

Oil Drain Bolt

Answer 31

A screw plug that's located at the bottom of an enine's oil pan that allows oil to drain when changing the oil.

Question 32

Bearing

Answer 32

A machine element that reduces contact between two surfaces while allowing for controlled movement without friction.

Question 33

Main Bearing Caps

Answer 33

Components that clamp the crankshaft into place by holding the main bearings and bolting to the bottom of an engine block.

Question 34

Journal

Answer 34

A part of a shaft that rotates inside a bearing.

Question 35

Shaft

Answer 35

An object with a long, narrow body, such as a pole or staff.

Answer 37

Main bearings, Rod bearings, Thrust bearings

Question 38

Main Journal/Block Journal

Answer 38

A cylindrical surface on a crankshaft that fits into the engine block and rotates inside the main bearing.

Question 39

Rod Journal/Crankpin

Answer 39

A cylindrical surface offset from the main journal centerline that fits into the connecting rod and rotates inside the rod bearing.

Question 40

Main Bearings

Answer 40

Bearings that hold a crankshaft in place within the engine block while allowing the crankshaft to rotate.

Question 41

Rod Bearings

Answer 41

Bearings that hold a crankshaft in place within a connecting rod while allowing the crankshaft to rotate.
