Why does my cummins fuel filter leak at the water seperator nozzle when engine is running?

Jul 31, 2007 by bluewaterhypozia | Posted in Maintenance & Repairs

Is it malfunctioning or is it a function indicating a dirty filter or what?

Bad connection - when was the last time the filters were changed????

Don't tell me how to fix it, okay? I already fixed it. It will not smoke like this any more, no matter what I do. All it needed was the second ...

T4i Compliance—Part 2

Particulate matter (PM) and nitrogen oxides, two significant constituents of diesel engine emissions, have been considered as two sides of a seesaw. On the one hand, high temperatures and excess oxygen are conducive to the formation of NOx. So lowering the in-cylinder temperatures and oxygen content reduces NOx; however, it also increases the production of soot (PM), thanks to lower fuel conversion efficiency. Decreasing both these constituents at the same time has challenged engine manufacturers to develop innovative and alternative solutions. Here are some of the ways we are doing it. Cooled Exhaust Gas Recirculation (EGR) recycles and cools a portion of the inert gases of the exhaust stream as they mix with incoming engine air. The Cummins short-loop EGR system routes the exhaust gas directly back to the cylinder. Combustion temperatures are thereby reduced, and therefore so is NOx. The cooling also increases the density of the charge air, boosting power. A faster and more powerful Electronic Control Module (ECM) improves fuel efficiency and power output while decreasing both NOx and PM emissions. These controls manage fuel quantity, injection timing and turbo boost pressure, and they consider account load, temperature, barometric pressure, fuel energy content, and even engine wear. The result is optimal combustion. The high-pressure common rail fuel system plays a big role in meeting the new T4i requirements. Increasing fuel pressures up to 1,800 bars (26,000 psi), along with the optimization of injection timing, reduces NOx without increasing PM or hydrocarbons. Alterations to nozzle design and injection systems themselves can have an impact as well. Additionally, multiple injection events per cycle enable matching of the load and fuel delivery thereby aiding emissions as well as fuel efficiency
