RYPOS Active Diesel Particulate Filter

RYPOS, Inc., developer of an advanced, self-regenerating filter that reduces harmful emissions from diesel engines, has been granted California Air Resources Board (CARB) Verification for its RYPOS HDPF/C™ filter. The Level 3 Plus CARB Verification states that during extensive tests, the filter reduced particulate matter by 85 percent or more on stationary diesel engines that power standby generators.

@urbex2007,The truck wasSTOCKnot one aftermarket part other then seat covers and a bed liner. I know what iv seen in person and your an ignorant green ass hole,I have a degree fromSLCCin diesel mechanics so dont tell me i dont know anything about diesels.UTA buss system have new DPF buses and we have had to replace turbos on them many times.The drivers had to be trained to drive on the hiway before parking them so the stupid DPFs could clean themselfs costing more money and increased bus fairs.

[urbex2007]

@123abcpa The engine was clearly faulty, not the DPF. The problem with diesel engines is when people use stupid devices sold by so-called "tuning" companies. They increase pressure on the fuel rail causing lots of soot as the diesel burns in the manifold, DPF, EGR, turbo etc. It makes exhaust valves stick open too. What you describe is a major engine fault, nothing to do with having a DPF fitted. Stop using deliberately false rumours when you know nothing about engines or how they work.

@babineau00, my father had a 2008 dodge ram with the 6.7 cummins and it burned up 3 turbos in just 28,000 miles. whatever DPF was used on it destroyed the turbos and gave it an avg mpg of about 11.5mpg. the previous model cummins without the dpf was much higher (around 17avg) and was known for its reliablity.

@123abcpa First - these are not used on Trucks - those are passive systems mostly. Second, the whole reason for an active system is to avoid just what you're pointing out. We call it "pollute to control" and you're right it doesn't make sense to do that. Rypos Active systems avoid this condition.

@babineau00 usually fun as im a mechanic, we had a 2.5 bmw on an 09 plate and wow, redline 2nd, 3rd and then 4th gear going down the M27... Corr you want power, noise and a thrill you try it!

[123abcpa]

@babineau00, True, but the build up from the DPF causes backpressure that causes the turbo to fail. The manufacture says its because the regen cycle was cut short by shuting the engine down before it was complete. They expect people to drive around so it can finnish, that waistes even more fuel and it will be dumping fuel into the exhaust thus waisting more just so it can clean itsself. I dont think it gets more wastefull then that. We are dumping fuel down the drain just so save on emissions.

@babineau00 Wow, all of that is really cool. 

[babineau00]

@master7chief There are three types of systems - fuel injected, electrical regen and passive regen. Passive needs engine heat - so in some situations you need to run the engine very hot to get rid of soot and hold down backpressure - fuel injection uses fuel at a much greater rate than electric, and electric works in all conditions - will passively regen if the engine is running hot, and will electrical regen if the engine is running cool.

[babineau00]

@123abcpa These don't add heat to the engine as they are on the exhaust side.

[babineau00]

@master7chief The ash is trapped in the filter, not passed through (there is something called blow-by which is a small amount going through the filter - but for the most part it's trapped). This type of filter is not used for trucks or cars. It's used on TRU's and Genset right now. But the TRU's are running on 12vots and yes, the alternator has to be beefed up, but the fuel penalty has been unmeasurable. Also, if the egine produces enough heat on it's own, then the Alt never gets used.
