Cost Efficient Electronic Control Unit for Low-Emission Motorcycle Engines: A Solution Based on the Integration of Analog Functions

The high level of pollution in urban areas and the growing significance of emissions from two-wheel vehicles is forcing many governments to enact stricter pollution regulations for these small motorcycle engines. In order to satisfy these new stringent exhaust emission levels, manufacturers are considering replacing traditional mechanical carburetors with electronic controls, but the strict target costs for two-wheel vehicles requires manufacturers to develop innovative designs for these electronics. This paper presents a new solution to reduce the total cost of the small engine electronic control unit: It is based on the integration of many necessary analog functions into a single chip.
