- Recirculation (EGR)
- valve returns some
- of the exhaust gas
- to the cylinders.
- This is done to
- lower the
- combustion
- temperature.
-
- Lowering the
- combustion
- temperature reduces
- the amount of
- nitrous oxide
- produced. Nitrous
- oxide combines with
- hydrocarbons in the
- atmosphere to form
- smog. This in turn
- reduces the amount
- of smog and
- pollution that we
- breathe.
