A vehicle with a production 1.6 litre 4 valve per cylinder engine that achieved Tier 0 (US87) emission standards, has demonstrated Low Emission Vehicle (LEV) capability. Minimal base engine modifications, the applications of auxiliary air injection and exhaust gas re-circulation (EGR) extended the hardware platform. The systems ultimate potential was achieved by a system specific software and calibration approach.
