quantity of gasoline, and clean the
tank thoroughly by shaking it.

The combustion process produces
carbon monoxide and hydrocarbons.
Control of hydrocarbons is very
important because under certain
conditions, they react to form
photochemical smog when subjected
to sunlight. Carbon monoxide dose
not react in the same way, but it is
toxic.
