Eaton Showcasing its On-Board Refueling Vapor Recovery System at Auto Shanghai 2015

Date: 2015/4/21

SHANGHAI … Power management company Eaton is showing its On-Board Refueling Vapor Recovery (ORVR) system at Auto Shanghai 2015. The vehicle emission control system collects fuel vapor that evaporates during a vehicle’s refueling process in order to burn it during normal operation. The technology reduces hydrocarbon emissions by approximately 95 percent during the vehicle refueling process, which accounts for approximately 50 percent of a vehicle’s total hydrocarbon emissions each year, and has been in use in the United States for nearly 20 years.
Industry data reveals that a large amount of hydrocarbons are forced out through the filler neck while a vehicle is being refueled, and that vapor leakage is then emitted into the environment to form smog. The Chinese government has begun drafting legislation for ORVR requirements to help address the country’s environmental and pollution issues. Final legislation is scheduled to be announced in 2015 with an effective implementation date of early 2017 for cities between Beijing and Guangzhou. 
“Currently, there are two types of fuel vapor recovery systems for refueling,” said Krishnakumar Srinivasan, president, Eaton’s Vehicle Group, Asia Pacific. “One method is the Stage II fuel vapor recovery system used at gas stations, and the other important emission control device is the On-Board Refueling Vapor Recovery system (ORVR). Eaton is committed to helping customers and governmental partners address their toughest power management challenges globally and locally, and we see our ORVR system as a proven solution with higher efficiency in helping to reduce hydrocarbon emissions.” 
ORVR systems were phased in by the United States from 1998 to 2001. Eaton was an early leader in the research and development of ORVR systems, and provided its first fuel vapor valve for an ORVR system in 1997. Today, Eaton develops fuel vapor valves for a range of customers throughout the world.  
ORVR systems are just one area that Eaton has been involved with related to technology solutions for lowering emissions. Another is a fuel vapor system for plug-in hybrid electric vehicles called the Fuel Tank Isolation Valve (FTIV). The FTIV is a multi-stage, electrically controlled valve that cuts off the fuel tank vapor path when the engine is not operating, which prevents hydrocarbons from overloading the carbon canister and escaping into the environment. When a vehicle is operating in electric mode, the FTIV can efficiently control the pressure in the gas tank and regulate the flow of hydrocarbons to the carbon container. This allows fuel vapor to be filtered once engine vacuum from the intake manifold is restored, and helps purge stored hydrocarbons to combust while generating engine power and liquid fuel. Eaton supplies several luxury vehicle plug-in hybrid models with its FTIV technology.
