PROGRESS TOWARD FEDERAL EMISSIONS RESEARCH GOALS: A STATUS REPORT

The 1977 Clean Air Act requires certain automobile manufacturers to conduct programs designed to develop emission control technology which can meet emission levels of 0.41 g/mi HC, 3.4 g/mi CO, and 0. 4 g/mi NOx. Development of closed-loop fuel control and improved catalysts has permitted significant gains toward achieving these low emission levels. All vehicles in the current research program use an exhaust gas oxygen sensor whose signal is processed by an electronic controller and used to control an electromechanical carburetor.
