High bandwidth control of the air-fuel ratio is necessary in order to minimize the exhaust emissions of sparkignition engines with three-way catalytic converters. A new approach is to implement a ...

This is a preview. Log in through your library . Abstract The method for measuring air-fuel ratio is generally based on analysis of the exhaust gas components and its calculations. A new instrument ...
