The Clean Air Act Amendments of 1990 have stimulated an increased interest in the determination of actual exhaust emission output from combustion sources. Actual levels assist in verifying operating permit compliance, facilitate the computation of emission fees or trading credits and enable a more comprehensive assessment of national emission inventory levels. An approach is described which continuously calculates expected emissions of nitrogen oxides, carbon monoxide and total unburned hydrocarbons based upon ongoing real-time measurements of engine operating parameters. These parameters in most cases are monitored utilizing existing sensors and can be easily submitted to microprocessor-based calculation algorithms. Calibration against factory and field performance data provides reasonable assurance of respresented accuracy.
