Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture. Large particles are carried from the road by rain into rivers, where they may leach toxic chemicals into the environment, whilst smaller particles become airborne and breathed in.
is entering into NO x exhaust gas catalyst manufacturing with its high-performance zeolite AQSOA used in a selective catalytic reduction (SCR) system. The zeolite (AQua SOrb) was originally developed as a zeolitic water vapor adsorbent. Mitsubishi Plastics, Inc.
The Audi valvelift system, which adjusts the lift of the valves in two stages, is active on the exhaust side. The main radiator, which dissipates the heat to the environment, does not come into play until the latest possible moment.
