Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have demonstrated a room-temperature method that could significantly reduce carbon dioxide levels in fossil-fuel power plant exhaust, one of the main sources of carbon emissions in the atmosphere.

Achates near-zero heavy-duty opposed-piston diesel enters fleet service; compliant with 2027 NOx levels

Green Car Congress

The project team also demonstrated that the engine reduces carbon dioxide by 10%. The cleaner engine is able to deliver ultra-low NO x by managing exhaust gas temperatures to ensure rapid catalyst light-off and by maintaining aftertreatment temperatures at optimum operating conditions in all driving conditions.

Europe Attempts Ban On Carbon Fiber

The Truth About Cars

European regulators have decided that carbon fiber should be on a shortlist of hazardous materials and are seeking to have it banned. Among the changes was an inclusion to ban the use of carbon fiber due to the fact that microscopic shavings can be produced whenever panels are destroyed or recycled.

NREL study probes emissions impact of butanol-gasoline blends in light-duty vehicles

Green Car Congress

Results of a study led by a team from the National Renewable Energy Laboratory on the impact of butanol-gasoline blends on light-duty vehicle emissions suggest that widespread deployment of n-butanol or i-butanol in the gasoline pool could result in changes to the estimated emissions of alcohols and carbonyls in the emissions inventory.
