In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). On current trends, the ratio may well continue to increase. A summary of the results is shown in the table and chart (log scale) below.

As part of its strategy of developing solutions to reduce CO 2 emissions, Valeo has acquired the Variable Torque Enhancement System (VTES) ( earlier post ) business of UK automotive technology development company Controlled Power Technologies (CPT). Unlike exhaust-driven turbochargers, electric superchargers are driven by an electric motor.

IAV has developed a particularly closed-coupled diesel exhaust gas aftertreatment (EAT) system. Under the EU6 standard, diesel engines are still allowed to emit up to 80 mg NO x /km milligrams of nitrogen oxides per kilometer—not only under the legal framework in the cycle but also in respect of increasingly tighter RDE requirements.

But even today, vehicles equipped with Bosch diesel technology can achieve as little as 13 milligrams of NO x in standard legally-compliant RDE cycles. A dynamic driving style demands an equally dynamic recirculation of exhaust gases. To ensure optimum NO x conversion, the exhaust gases must be hotter than 200 degrees Celsius.

legal light-duty vehicles from 1984 to present. These vehicles conserve fuel by only powering 4 cylinders at lower speeds, and then switch to 8 cylinders when needed to meet the power demand at higher speeds. The Chrysler data included a vehicle that appears to employ protective enrichment at 80 mph.

l/100 km [147 – 157 mpg US] in the WLTP cycle; combined electric power consumption of 30.1 – 28.9 liter unit features a cross-bank exhaust manifold and an optimized oil separation process. kWh/100 km in the WLTP cycle; and CO 2 emissions of 36 – 33 g/km in the WLTP cycle. The BMW XM is also the first BMW M original since the BMW M1.

The new family of engines is tailored to the requirements of commercial vehicles, while also extending the power range. Exhaust gas aftertreatment is accomplished by an oxidation catalyst with a downstream combination of diesel particulate filter and SCR catalytic converter. The newly developed 2.0 TDI BiTurbo for light duty vehicles.
