|
| Cams |
Eccentric
shafts used in most internal combustion
engines to open and close valves. |
| Carbon
Residue |
Coked
material remaining after a oil
has been exposed to high temperatures
under controlled conditions. |
| Catalytic
Convertor |
An
integral part of vehicle emission
control systems since 1975. Oxidizing
converters remove hydrocarbons
and carbon monoxide (CO) from
exhaust gases while reducing converters
control nitrogen oxide (Nox) emissions.
Both u se noble metal (platinum,
palladium or rhodium) catalysts
that can be "poisoned"
by lead compounds in the fuel
or lubricant |
| Cetane
Number |
A
measure of the ignition quality
of a diesel fuel, as determined
in a standard single cylinder
test engine, which measure ignition
delay compared to primary reference
fuels. The higher the Cetane Number,
the easier a high-speed, direct-injection
engine will start, and the less
"white smoking" and
"diesel knock" after
start up. |
| Cetane
Number Improver |
An
additive (usually an organic nitrate)
that boosts the Cetane Number
of a fuel. |
| Cetane
Index |
A
value calculated from the physical
properties of a diesel fuel to
predict its Cetane Number. |
| Cloud
Point |
The
temperature at which a cloud of
wax crystals appears when a lubricant
or distillate fuel is cooled under
standard conditions. Indicates
the tendency of the material to
plug filters or small orifices
under cold weather conditions. |
| Cold
Cranking Simulator (CCS) |
An
intermediate shear rate viscometer
that predicts the ability of a
oil to permit a satisfactory cranking
speed to be developed in a cold
engine. |
| Compression
Ratio |
In
an internal combustion engine,
the ratio of the volume of combustion
space at bottom dead center to
that at top dead center. |
| Copper
Strip Corrosion |
A
qualitative measure of the tendency
of a petroleum product to corrode
pure copper. |
| Corrosion
Inhibitor |
Additive
that protects lubricated metal
surfaces from chemical attack
by water or other contaminants. |
| Crown |
The
top of the piston in an internal
combustion engine above the fire
ring exposed to direct flame impingement.
