A New Microprocessor-Based Automotive Diesel Pump Controller

A control system for a new diesel rotary distributor pump has been developed. The system is applied on multicylinder, indirect injection engines, both turbocharged and naturally aspirated. Precise, full authority control of fuel quantity and injection timing is the primary function of the system, with benefits to emissions, driveability rated output, and fuel economy. Idle speed governing, cruise control, and exhaust gas recirculation (EGR) control are important features. Transmission torque converter lockup is decided by the system for vehicles with automatic transmissions. Self-diagnostics are provided to assist servicing.
