Carbon monoxide (CO), it is a byproduct of combustion reaction, or burning of certain fuels. CO can be emitted from gasoline – powered engines, natural gas heating systems, oil, Coal, wood etc.
Acceleration rate of vehicle significantly impacts the tailpipe emission.
It is known from the studies that, Emission rate increases with increase in acceleration,
In a study reported by Frey et al. the minimum emission is observed at idling (at lower acceleration). At idling, since there is no power or speed requirement by engine (since there is no acceleration), the fuel consumption is minimum and hence the rate of emission is minimum.CO has effect on human body. Breathing CO can cause headache, dizziness, vomiting, and nausea. If CO levels are high enough, you may become unconscious or die. Exposure to moderate and high levels of CO over long periods of time has also been linked with increased risk of heart disease
