EPA collects penalties for alleged automobile ‘defeat device’ violations by two Iowa companies

Green Car Congress

The US Environmental Protection Agency (EPA) has reached settlements with two Iowa companies for allegedly tampering with car engines to render emissions controls inoperative, in violation of the federal Clean Air Act. Numerous studies also link diesel exhaust to increased incidences of lung cancer.

York, Empa study finds retrofitting of VW diesel engines was successful

Green Car Congress

The VW diesel scandal began on 18 September 2015. On the opening day of the Frankfurt International Motor Show (IAA), the US Environmental Protection Agency (EPA) published a Notice of Violation: VW diesel engines with 1.6 liters displacement (type code EA 189) contained illegal software designed to manipulate emissions.

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. There was no significant difference in the profiles of total carbonyl emissions between CFT and DF. Jakober, 2008). reduction in total carbonyls and a 6.0–100%

Environment Canada study finds vehicle exhaust a significant source of isocyanic acid; suggests consideration of new emission standard

Green Car Congress

Researchers at Environment Canada have found that vehicle exhaust is a significant source of isocyanic acid (HNCO), a toxic gaseous acid that is a product of various forms of combustion and a potential health concern. mg kg fuel –1 and were significantly higher than previous biomass burning emission estimates.

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. Wang et al.,

Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. Automobile tire rubber in general consists of approximately 40?
