- Beginning in 2014, the most stringent governmental emissions standards in history went into effect for high-horsepower, off-road equipment.
- Case IH met the Stage IIIb challenge with an fuel-efficient SCR after treatment system.
- SCR-only! Case IH continues the commitment to meet Stage IV (Tier 4 Final) emission standards without exhaust gas recirculation and without particulate filter.
- Stage IV: 80% further Nitrogen Oxide (NOx) reduction compared to Stage IIIb.
No further reduction of Particulate Matter (PM).
Stage V, the new regulatory step introduced in Europe in 2019/2020 (depending on engine power level), further tightens the limits on PM emissions: admitted PM quantity has been reduced by 40% compared to Stage IV and a new limit has been introduced on the number of emitted particles (Particle Number Limit, PN).
