Summary

In major automotive markets (China, USA, Europe), more stringent emission legislations are planned (CARB LEV IV) or in preparation (EU7, EPA Tier 4, CN7) from model year 2026 onwards with the target to further reduce traffic-related criteria pollutant emissions. This is an additional challenge for the automotive industry beside the introduction of CO₂ reduced/neutral powertrains. Therefore, the target is to fulfil future emission limits under tightened and real driving relevant boundary conditions with reasonable add-on costs. This ensures affordable future mobility, especially for cost-sensitive market segments, e.g. entry-level vehicles.

BOSCH has already demonstrated for diesel and gasoline vehicles, how exhaust emissions can be reduced significantly with a comprehensive system approach. This paper focuses on further developed hardware solutions and newly developed software solutions for gasoline vehicles and considers the NO_X sensor which is expected to be required for EU7 on-board monitoring (OBM).
