IAV develops new close-coupled diesel exhaust gas aftertreatment system for improved emissions reduction

Green Car Congress

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.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.

Bosch says it has solved diesel NOx problem; as low as 13 mg NOx/km even under RDE; refining existing technologies

Green Car Congress

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.

Volkswagen Group introducing Modular Transverse Matrix this year; new engine families, lighter weight construction, powertrain flexibility

Green Car Congress

Two systems integrated in the MQB strategy which play a key role here are the modular gasoline engine system (MOB) with the new EA211 engine series (40 kW / 54 hp to 110 kW / 148 hp). EA211 series gasoline engines. The advantage is that the exhaust line, driveshafts and gearbox mounting position can be standardized.

Perspective: Europeans in the lead with range extenders for hybrid vehicles; 2nd vs. 3rd generation

Green Car Congress

We are in the decade of the hybrid electric vehicle despite the fact that most off-road and underwater vehicles are pure electric. Indeed, most electric aircraft are pure electric as well. These vehicles are mainly small, as are electric two wheelers which are also almost all pure-electric.

London and Paris launch car scoring initiative based on real-world emissions; ICCT the technical lead

Green Car Congress

This new undertaking will capture detailed information on pollutants from vehicle exhaust using remote-sensing equipment and portable emissions monitoring systems. Other labeling schemes, such as the Crit’Air program, certify vehicles’ environmental class based on pollutant emissions, and may distinguish diesel from gasoline powertrains.
