17
Q

Engine Block

A

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

18
Q

Engine Head/Cylinder Head

A

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

19
Q

Which components are housed within the engine head?

A

Combustion chambers, valves, and spark plugs.

20
Q

Which components are housed within the engine block?

A

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

21
Q

Crankshaft

A

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

22
Q

Balancing Lobes/Counterweights

A

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

23
Q

Oil Seal

A

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

24
Q

Bearing Surface

A

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

25
Q

Oil Filter

A

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

26
Q

Lubrication Holes

A

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

27
Q

Oil Passages

A

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

28
Q

Oil Pan

A

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

29
Q

Oil Pump

A

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

30
Q

Oil Drain Bolt

A

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

31
Q

Bearing

A

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

32
Q

Main Bearing Caps

A

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

33
Q

Journal

A

A part of a shaft that rotates inside a bearing.

34
Q

Shaft

A

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

35
Q

Crankshaft Journals

A

Main journals, Rod journals/Crankpins

36
Q

Crankshaft Bearings

A

Main bearings, Rod bearings, Thrust bearings

37
Q

Main Journal/Block Journal

A

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

38
Q

Rod Journal/Crankpin

A

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

39
Q

Main Bearings

A

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

40
Q

Rod Bearings

A

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

41
Q

Thrust Bearings

A

Bearings that reduce axial movement of the crankshaft and help it maintain position.
