The
basic
relationships between
the
four
components of combust'ion
are
HC
(Hydrocarbon
=
Fuel),
CO
(Carbon
Monoxide), 02
(Oxygen)
and
CO2
(Carbon
Dioxide).
The
relationships can
vary
by engine,
depending upon
age, condition
and
engine temperature.
Mal-adjusted carburetion
or
injection and
ignit'ion
timing
will also
influence this relationship drastically.
