Turbocharging the 1981/2-1984 Ford 2. 3L OHC engine

OSTI ID:6045091

Successful application of turbocharger technology to the Ford 2.3L OHC engine requires management of thermal loading. The 1979/1980 2.3l draw-thru carbureted engine was octane and spark advance limited, requiring calibration to worse case 91 ron conditions. Since no adaptive calibration control was possible relatively late ignition timing compromised engine performance. To improve performance, driveability, fuel economy and emission control, work was initiated in mid 1980 on a blow-thru electronic fuel injected engine schedulated for 1983 1/2 production. Program assumptions were issued specifying a tuned EFI blow-thru inlet system, exhaust manifold mounted airesearch T03 turbocharger with integral wastegate and 8.0:1 compression ratio with a dished piston. Also included were base engine revisions to accommodate increased thermal and mechanical loads. Fuel and spark advance/retard control with ford's new EEC-IV microprocessor allowed considerable flexibility to schedule a varying calibration against changing conditions.
