BASF Debuts Automotive Air Intake System Hydrocarbon Trap

BASF today introduced the innovative EvapTrap™ automotive air intake system hydrocarbon trap. This patented technology is applied directly onto the surface of a vehicle’s air intake box to adsorb engine hydrocarbons without increasing backpressure.

The Air Resources Board of California has adopted new LEV III emissions regulations which go into effect in 2015, requiring automakers to further reduce evaporative emissions. The so-called Super Ultra-Low Emissions Vehicle (SULEV) standard under these regulations specifies near-zero evaporative emissions.

“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,” said Nick Leclerc, Product Manager, BASF Mobile Emissions Catalysts.

The air intake system is a key source of evaporative emissions for automobiles as hydrocarbons in the engine’s fuel source can leak out through the system when the car is not running.

“Traditional solutions involve adding an activated carbon honeycomb or filter to the air intake box to adsorb the hydrocarbons,” Leclerc said. “However this approach can increase backpressure, reducing horsepower and fuel economy. EvapTrap, on the other hand, addresses the evaporative emissions challenge without any backpressure increase.”

Evaporative emissions are measured in a “SHED” (Sealed Housing for Evaporative Determination) test, which is a drive-in chamber built for the purpose of testing the fuel emissions of a vehicle that are not related to engine exhaust. The EvapTrap has been successfully SHED-tested and proven to offer adhesion durability to all air intake box materials, including polypropylene. It is also a tamper-proof solution.

The EvapTrap is part of BASF’s SULEV System Solutions portfolio which includes advanced TWC (Three Way Conversion) catalysts, PremAir® direct ozone reduction catalysts and FWC™ (Four Way Conversion) catalysts to meet the tightest emission regulations.
