Lubricate Parts
A device that allows motion between parts and reduced friction
Bearings
Name 2 different factors that affect friction
Pressure and Speed
is the movement of h eat through solids.
Conduction
The ratio of water to antifreeze is
50:50
The __________ device is used to measure temperature of the coolant
Thermostat
A mechanical device that pressurizes oil and forces it through the oil galleries to lubricate the engine.
Pump
Which is thicker, SAE 20 or SAE 40 oil?
40
is the transfer of heat in mass amounts through air (and sometimes liquid s) .
Convection
Antifreeze is a necessary additive because it increases what
the boiling point
The ____________ is a part of the small cooling circuit and is used in part to heat the interior cabin of the car
Heater Core
Storage location at the bottom of the engine for oil to be captured and recirculated.
Oil Pan or Sump
This type of oil is made to function properly at high and low temperatures
multi-viscosity
is the transfer of heat through space, like the heat you feel from the sun.
Radiation
When the coolant is cold it bypasses this
large cooling circuit
The _____________ is a part of the large cooling circuit and is very effective at quickly removing heat from the engine
Radiator
Drilled or cast channels in the engine block to carry oil to areas needing lubrication.
Oil Galleries
This system is the most basic of the lubrication systems
Splash
This type of heat transfer does not require any contact is required
Radiation
Radiator Cap
The cylinders in the engine block are surrounded by the ___________ which use coolant to remove heat from the cylinders
water jackets
The area of a shaft (crankshaft or camshaft) where bearings are located
Bearing Journal
This type of lubrication system is most commonly found on an automotive engine
Combination System
Conduction
Instead of water jackets, air cooled engines use these around the cylinder heads to cool them
Cooling fins
These help increase airflow into the radiator
fans
