Top EVAP Tips When Replacing Fuel Pumps
Nothing is worse that an EVAP code after a fuel pump has been replaced. Discovering that the tank needs to be dropped again to address a problem can kill shop productivity and profitability. Keep reading for tips that can help you avoid comebacks and dropping the tank for a second time.
Finding The Leak: Detecting Small EVAP Leaks
Leaking vapors of fuel are more destructive to the environment than tailpipe emissions. The vapors from an Evaporative emissions system (EVAP) contain volatile organic compounds that can cause health problems and contribute to haze and smog in some cities. In China, much of the pollution in cities is caused by unburned fuel vapors.
Evaporative Vapor Emissions Control
These EVAP monitors can be run in two different ways. Ford, GM and some Asian imports use a vacuum to run the monitor. Chrysler, most European and a few Asian products use pressure to run the monitors.
Diesel Exhaust Particulate Filters: How Do They Work, What Do They Do?
The Diesel Particulate Filter (DPF) is a ceramic filter that has thousands of tiny channels or honeycomb-shaped openings that trap the soot onto the channel walls and prevent the particulate matter (down to 1 micron) from exiting out the tailpipe. The honeycombed inner structure is covered with a layer of a chemical catalyst that contains small amounts of precious metals, usually platinum or palladium.
