Carburetors With Electronic Devices for Future Specifications of Exhaust and Fuel Consumption
Published January 01, 1980 by Verlag Des Verein Deutscher Ingenieure GmbH in Germany
Continuously increasing demands on carburetors have resulted in growing complexity of additional pneumatic, mechanical, and electric equipment. Future requirements will necessitate different solutions. Carburetors equipped with electronic controls will be of increasing importance during the next decade. The paper reviews design criteria of such controls and then discusses different, proposed systems.
Electronic controls offer improvements over current carburetion systems in fuel consumption, exhaust emissions, driving performance, and idling stability, especially during engine warm-up periods. Furthermore, besides their obvious adaptability to integrate with other electronic engine components, the cost and reliability of these systems are promising. Each proposed system offers a different collection of sensing and control functions and the capabilities of all the systems are tabulated for comparison. The functions of many of the individual mechanisms contained within these systems are described in greater detail.
