The effect of air/fuel ratio on the CO and NOx emissions for a twin-spark motorcycle gasoline engine under wide range of operating conditions

Energy, 2019
In the present study, the possibility and limitation of lean burn in a motorcycle engine were explored, from the aspect of exhaust emissions. The CO and NOx emissions were studied by experimental measurements and combined simulations on a twin-spark ...

On the road to NOx emissions trading

The Electricity Journal, 1995
Abstract With costly emission reductions looming, a national trading program in SO 2 emissions as a precedent, and a climate of increasing acceptance of emissions trading, many states are now considering emissions trading a viable option. States should take decisive actions to develop innovative, least-cost programs for ozone reduction before the ...

Analysis of the high instantaneous NOx emissions from Euro 6 diesel passenger cars under real driving conditions

Applied Energy, 2019
In real-world driving, most Euro 5 and 6 diesel passenger cars exceed the nitrogen oxides (NOx) emission limits of type approval procedure. The emission factors of the fleet of Euro 6 vehicles show high variability, irrespective of the NOx control ...
