Catalytic Exhaust Emission Control of Small Internal Combustion Engines
ABSTRACT Gaseous emissions present in the engine exhaust of on-road motor vehicles are subject to stringent exhaust emission 2ontrol standards for carbon monoxide (CO), hydrocarbons, and oxides of nitrogen (NOx). All major automobile manufacturers utilize three-way catalytic converters to meet these standards. There are millions of small engines in on-road and off-road applications whose ...

Strategies for controlling pollution from vehicular emissions in Beijing
Beijing is one of the most polluted cities in the world, which is caused by surprising vehicular growth in the past decade. This paper describes the severe situation of vehicular emission pollution in Beijing, and discusses the following strategies for mitigation: improving fuel quality, controlling the exhaust from new vehicles, controlling the emissions from vehicles in use through, e.g., ...

Comparison of EGR ratios determined by four different methods for electronic re-circulation gate control
In this study, low pressure systems have been applied for exhaust gas recycling (EGR), which is applied in certain operating conditions. Induction air, exhaust gas flow, amount of exhaust gas added to the induction air, amount of carbon dioxide (CO2) in the exhaust gas, and amount of carbon dioxide in the induction air mixed with the exhaust gas, have been measured and the EGR ratio has been ...

Case study - Paint booth over spray
OVERVIEW A major automotive component supplier needed to control the emissions from its paint spray process. The plant emissions had characteristics common to many paint spray plants: high air flow, low volatile organic compound (VOC) concentration and particulate. The company needed an emission control solution that had low operating costs and that could also fit in their limited space. System ...
