Exhaust Emissions from a Ford Pinto Equipped with the General Dynamics Electrosonic Control System

摘要

The EPA receives information about many systems which appear to offer potential for emission reduction or fuel economy improvement compared to conventional engines and vehicles. One such system has been developed jointly by General Dynamics and Autotronic Controls Corporation. This system is called the Electronic engine Control System (Electrosonic), and utilizes the principles of lean-burn combustion to control exhaust emissions. The Electrosonic system is designed to control engine parameters affecting exhaust emissions. As such, the system controls ignition timing, air-fuel ratio and idle speed. The system does have EGR control capability, although EGR was not on the 1976 Ford Pinto MPG supplied to the EPA for evaluation.
