Development of a Lean-Burn Natural Gas Engine Control System. Topical Report,August 1991-June 1993

摘要

The objective to this project was to develop a dedicated natural gas electronicfuel control system for lean-burn heavy-duty engines. The control system would incorporate closed-loop control to enable engines to meet 1994 CARB heavy-duty emission levels without aftertreatment. Other features required in the control system included idle speed control, mid-range speed governing, and engine safeties.
