Summary:

A microcomputer control system for managing the automotive engine's air-fuel ratio, spark ignition timing, exhaust gas recirculation and idle speed has been developed and is marketed in Japan under the name of ECCS.By installing this system in a 1,500 kg vehicle's 6 cylinder 2.8 liter engine, the four factors listed above have been controlled so precisely that their optimum relative calibration has been realized.As a result, fuel economy has been improved by 10% while good drivability has been maintained.This paper outlines ECCS and describes how control factors in a "steady state" are determined. It also discusses the control sequence in transient conditions, such as "cold" starts, "hot" restarts, clutch engagement, acceleration, deceleration, gearshifts and the "warm-up" process
