CONTROL OF THE HOMOGENEOUS-CHARGE PASSENGER-CAR ENGINE--DEFINING THE PROBLEM

The engine control problem is discussed as it concerns the controls engineer, including the need to provide maximum fuel economy within emission constraints at acceptable levels of driveability, reliability, and cost. The effects of spark advance, air-fuel ratio, and exhaust gas recirculation on fuel consumption and exhaust emissions (hydrocarbons, carbon monoxide, and nitrogen oxides) are reviewed. The Federal Test Procedure for emission certification and emission control systems (oxidizing catalytic converter, three-way catalytic converter) is described. System deterioration, combustion knock, octane requirements, driveability, cold start, dynamic effects, control system anomalies, reliability, and cost are discussed in terms of engine control.
