Audi presents latest SQ5 TDI diesel; 48V MHEV & electric compressor

Green Car Congress

Audi has introduced the latest version of the SQ5 TDI diesel. The SQ5 TDI was first introduced in the fall of 2012 as the first Audi S model powered by a diesel engine. It accelerates the top model of the Q5 product line from 0 to 100 km/h (0 to 62.1 Two SCR catalytic converters interact: the exhaust gas aftertreatment.

First online measurement of gaseous sulfuric acid in diesel exhaust helps clarify role in formation of nucleation particles

Green Car Congress

Researchers in Germany and Finland report the first online measurement of gaseous sulfuric acid (GSA) in the exhaust gas of a modern heavy-duty diesel engine in an effort to quantify the role of low-vapor-pressure gases in the formation of nucleation particles (NUP). of hydrocarbons) significantly. of hydrocarbons) significantly.

Study finds gasoline exhaust contributes more to formation of secondary organic aerosols than diesel

Green Car Congress

Contrary to expectations, exhaust from gasoline vehicles contributes more to the production of secondary organic aerosols (SOA) than exhaust from diesel vehicles, according to a new study by scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES), NOAA’s Earth System Research Laboratory (ESRL) and other colleagues.

New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Mullite is not only easier to produce than platinum, but also better at reducing pollution in diesel engines. Kyeongjae Cho. CO 2 + 2NO, NO 2 + C?CO

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. This phase was conducted at SwRI in 2012.

DOE awards $17M to FY 2014 SBIR Phase II projects; includes Si/graphene anodes, motor windings, exhaust treatments

Green Car Congress

The selected 17 awards represent the best of nearly 1,000 ideas submitted for the FY 2012/13 Broad Based Topic Solicitation, DOE said. Vehicle technologies span a range from new Si/graphene Li-ion anode materials and composites for motor windings to diesel aftertreatment and advanced lubricants. Lead organization. Description.

Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

Green Car Congress

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. Diesel particulate filters (DPF) and urea-based selective catalytic reduction (SCR) exhaust after-treatment systems thus have emerged as feasible strategies to meet the 2010 USEPA regulations.
