Bottom End
This component has passages for cooling and lubrication.
What is an engine block?
This houses the components of the valve train and the spark plugs.
What is the cylinder head?
This system cleans, cools, and circulates oil to moving parts of the engine.
What is the lubrication system?
This system ensures that the engine is operating at the required temperature.
What is the cooling system?
This system supplies a high voltage to the spark plugs.
What is the ignition system?
This component converts reciprocating motion to rotary motion.
What is the crankshaft?
These holes in the cylinder head match the cylinder block to allow coolant to pass from the block to the head for engine cooling.
What is the water jacket?
This strains out dirty particles found in the oil system.
What is an oil filter?
This component forces coolant through passages in the engine.
What is a water pump?
This component generates enough voltage to create a spark across the spark plug gap.
What is an ignition coil?
This material is used for the construction of an engine block.
What is cast iron?
These valves are always bigger than the other valves.
What are the intake valves?
Oil travels throughout the engine through these.
What are oil galleries?
This transfers unwanted heat from the coolant to the atmosphere.
What is a radiator?
These carry high voltage to each spark plug and use a carbon stranded conductor and silicone insulator.
What are spark plug wires?
This component is exposed to rapid changes in speed and direction.
What is a piston?
This component controls the opening and closing of intake and exhaust valves.
What is a camshaft?
This system stores oil in a separate tank and the oil pan is much smaller.
What is a dry sump system?
This component is closed when the engine is cold and opens when it reaches proper operating temperature.
What is the thermostat?
This stores data about correct ignition timing under different conditions.
What is an electronic control unit (ECU)?
Most piston have two of these for compression, and one for oil control.
What are piston rings (rings)?
This valve train arrangement has no lifters.
What is an overhead cam configuration (OHC)?
This term describes the flow rate of oil (SAE 10, 20, 30, etc).
What is viscosity?
This is typically a 50/50 mixture of water and ethylene glycol to increase boiling point, decrease freezing point, and reduce corrosion.
What is coolant (antifreeze)?
In older vehicles, which part moves to distribute high voltage to each spark plug at the cylinder?
What is a rotor?
