Electronic Engine Controls - Availability, Durability, and Fuel Economy Effects on 1983 and Later Model Year Light-Duty Trucks

摘要

The application of microprocessor technology to optimize the functions of the internal combustion engine is underway. Passenger car model years 1980 and 1981 have seen the widespread introduction of electronic engine controls of varying degrees of complexity. These controls hold the promise of lowering engine emissions and raising engine fuel economy through the optimization of the combustion processes at all engine operational conditions. This paper examines the potential of this technology for use in the future light-duty truck fleet. The implications of this technology on fleet fuel economy, in conjunction with the more stringent emission standards in 1983, are examined along with projections as to the future availability and durability of these microprocessors and their associated engine sensors.
