However, these approaches increase the backpressure, reducing horsepower and fuel economy. The EvapTrap provides a powerful solution to meet pending SULEV evaporative emissions standards while allowing auto manufacturers to use their existing air intake box, thus reducing complexity and cost for the OEM.

de-ionized water, also known as Diesel Exhaust Fluid (DEF) or AdBlue, into the exhaust stream. The EcoFit Urea Dosing System delivers improved Oxides of Nitrogen (NO x ) conversion efficiency which gives customers the opportunity to tune engines for improved fuel economy or to reduce the size of a typical SCR system.

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.
