본문내용
A lean burn engine is designed to operate with a very lean air-fuel ratio
during light load conditions. Most modern gasoline engines are controlled
to run at a chemically correct (stoichiometric) air fuel ratio (about 14.7:1)
to make the three-way catalyst operate at high efficiency, reducing
tail-pipe emissions. Lean burn engines mix more air with the fuel when
full power is not needed, resulting in better fuel economy. Air/fuel ratio
in lean burn engines can be as high as 22:1. When full power is
needed, such as during acceleration or hill climbing, a lean burn engine
reverts to a stoichiometric (14.7:1) ratio or richer.
