OE FUEL VAPOURISATION VALVES
A fuel vapour valve is an electrically heated glow plug that evaporates the diesel fuel, then injects it into the exhaust gas stream directly before the DPF. The fuel vapour valve incinerates particulate matter (PM) without oil dilution and requires no additional cooling, helping to improve fuel economy and CO2 emissions. It also enables more frequent DPF regeneration with low load conditions and when idling, allowing for an extended operating range.
It is thought that around 80% of Ford DPF issues can be directly linked to the failure of these components
The valve�s proprietary design works to virtually eliminate clogging over the lifetime of the product, providing good diesel fuel distribution and low backpressure. The part also benefits from minimised heat losses, resulting in fuel-efficient DPF regeneration due to heat generations close to the DPF, producing no secondary emissions. Fuel vapour valves also avoid oil dilution, along with the engine breakdowns and increased need for oil service that may result from them.
Compared to an injector, a fuel vapour valve requires less mixing length and no additional cooling, with easy installation and replacement for technicians. No special tools are required, just a possible bleed of the valve when refitted, with a fluid container to collect any excess diesel and an ammeter.
