The BLADE Blade Your Ride: Save Gas, Save Money, Stop Global Warming is a filter that fits over the end of your tailpipe. They claim that: It prevents soot from exiting your tailpipe and out into the atmosphere It keeps the hot exhaust gasses in your tailpipe longer, thereby warming up the catalytic converter more quickly (it apparently makes the pulses of engine exhaust into a more constant stream by restricting the flow rate). So my question is: how much of this is rooted in logical arguments? I see they're showing scientific data tests from 3rd parties in Brazil and California. I have an engine block heater, so would this really be of any benefit? Does the EBH help warm up the catalytic converter, or does the onboard computer assume it's warm because the engine is? The blade seems pretty spendy at $200, and each cartridge is $20 and is rated for 5-10K miles. So, is there any logic in buying this for a Prius (especially one with an EBH)?
Restricting the outlet and holding more back pressure will heat the cat up sooner I suppose, but it also would tend to reduce power output when you need it most. I doubt that this would be a good idea for the Prius as the ICE is not exactly a monster anyway. I would be interested in hearing what someone who has used one has to say.
It's a crock o' sh!t. Toyota spent years optimizing the system for emissions and fuel economy. Some doofus piece of chicken wire is not going to improve it.
More snake oil. The exhaust system on the Prius is already optimized for the Prius. Add this to the dumpster with the fuel line magnets and the HHO generators. Tom
oh no! and my combination magnet hho generator blind safe noise maker just got here! shoot. I should read here closer!!!
Hi All, For $200 it should at least turn itself off when the catlytic converter is up to temperature. All it is is a tube, clamp, screen, and some high temperature porous insulation.
