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. Future diesel powertrains will need to be capable of meeting limit values that are even tighter than EU6. This way, exhaust gas flows through DOC and SCRF before it enters the turbine. —Matthias Diezemann.

ETH Zürich team developing light-duty natural gas-diesel hybrid electric powertrain; 43 g/km CO2

Green Car Congress

Consumption measurements of the dual-fuel natural gas-diesel engine as a function of speed and load. Researchers at ETH Zürich have developed a light-duty hybrid electric vehicle featuring a dual-fuel natural gas-diesel engine. The ignition delay is mainly dependent on the chemical reaction kinetics of the diesel fuel.

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The current decline is ales of diesel light duty vehicle in Europe does not put EU CO 2 targets out of reach of automakers, according to a new analysis by the International Council on Clean Transportation (ICCT). In addition, vehicle manufacturers increasingly use electric motors to complement conventional combustion engines in cars.

Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

Other research has shown that carbonyls directly influence physiological response to diesel exhaust particles and can also contribute to secondary organic aerosol formation.
