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?

Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. As cars have become more fuel-efficient, however, they use less energy and the temperature of the exhaust gases is lower, which makes it harder to clean up the pollutants. —Yong Wang.

Their SOFC system can be operated without consuming the anode fuel (a reductant) at temperatures near that of the engine exhaust to eliminate the need for reductant refilling and extra heating. The NO x concentration in the exhaust of an automotive gasoline engine with spark ignition can be as high as 4000 ppm. —Huang et al.

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. Oxidation of engine-generated NO to NO 2 is critical in diesel engine emission control for reducing NO x and carbon soot from the tail-pipe exhaust.

Current gasoline-powered vehicles lose about 70% of the available energy through engine losses (mostly through exhaust heat). However, when considering usable energy, things get more complex, as highlighted in the following paragraph. In turn, not all of the available energy in food is digested.

-alumina supports along with a small amount of lanthanum oxide can efficiently turn the carbon monoxide in automotive exhaust into carbon dioxide at temperatures as low as 40 ?Celsius, Most of the pollutants from a modern automobile are emitted during the first 30 seconds of starting a car, when the catalyst is still being warmed.

Numerous studies also link diesel exhaust to increased incidences of lung cancer. These problems include premature mortality, aggravation of respiratory and cardiovascular disease, aggravation of existing asthma, acute respiratory symptoms, chronic bronchitis, and decreased lung function.
