BASF introduces EvapTrap automotive hydrocarbon trap for LEV III evaporative emissions compliance without backpressure increase

Green Car Congress

The California Air Resources Board (ARB) has adopted new LEV III emissions regulations which go into effect in 2015, requiring automakers to further reduce evaporative emissions. However, these approaches increase the backpressure, reducing horsepower and fuel economy. It is also a tamper-proof solution.

Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

The found that using a GPF did not show any fuel economy and CO 2 emission penalties, while the emissions of total hydrocarbons (THC), carbon monoxide (CO), and nitrogen oxides (NOx) were generally reduced. This study showed that GDI vehicle exhaust is characterized by diverse PAH distribution profile, ranging from 3-6 ring species.

Review of research suggests inconclusive support for fuel consumption benefits of catalyzed EGR

Green Car Congress

Conflicting evidence does not support making a firm conclusion on the fuel consumption benefit of catalysed Exhaust Gas Recirculation (EGR), according to a review of current studies by a team at the University of Bath (UK). According to the review, the conversion of HCs, CO, and NO in the exhaust gas by the catalyst can result in up to a 4.5%
