InTech 80% reduction in emissions for cars as from November

[Humpty's Revenge]

Has anyone seen this little valve that is being released in November that reduces up to 80% of carbon Etc?

Now I missed most of this on our local news tonight but it was originally made just for motorbikes but is being released soon for cars too.

Now if this is the facts & it will work with our cars then we potentially have a massive solution to our emissions problems!

My questions would be can it harm anything on the car? does it reduce power at all? & generally is it going to be safe & work?

I have no idea how much it will be & I have really only found old web sites that are to do with bikes only which is linked below:-

Maybe some bods on here have anything to say about this possibly?

if you look at the thread in the link this goes back to 2009 discussion. so it is an old product.

"the valve opens in time with every piston down stroke"
http://news.bbc.co.uk/1/hi/england/7953443.stm

it doesn't say if it is releasing crank case pressure or inlet vacuum pressure. either way it does sound right. i don't see where else it could be fitted. am i missing something?

crank case pressure is already released back in to the inlet pipework before the turbos, but after the MAF.

inlet vacuum pressure based on a non turbo car, you need the inlet vacuum pressure to suck in the fuel air mix into the piston.

try this link it explains it a bit more

i can see one of the benefits of the intech on a motorbike with the reduction of engine braking when you close the throttle with a snap shut and possibley cause the rear wheel from locking up.
Butterfly valve closes and effectively causes a vacuum in the plenum chamber, but the engine is still running and trying to draw in air through the inlet valve and has a great resistance on the pistons due to the vacuum in the plenum. This valve is supposed to allow extra air into the plenum to stop the happening. i don't see how it makes the fuel burn better, because when the intech is working there is no fuel going into the engine anyway. but again i must be missing something.

i am not too sure if this would benefit a car just from the engine braking point of view though.

So why was it on our news today stating for cars this November?

I know it's an old site but I cannot find anything up to date bud.

[Humpty's Revenge]

Right found this which does indeed state what I thought I heard.

yeh i searched and found nothing from more recent than 2009.

i will check out your link.

sound like it was recent thing.

but i have thought about something else that might not make it a good idea.
cars use the vacuum in the plenum chamber when you lift off the accelerator to drive the brake servo, vacuum assistance. if you let air into the plenum when you lift off the accelerator surely you would loose some of that assistance.

Check this bud, iplayer time around 4.06 in.

been a while since i have seen south today news report, i don't get down to my parents, in Fareham.
it looks completely real, but i can't see how letting unmetered air into the plenum when the inlet valve is open helps the burn, surely all you are doing is leaning out the burn, and if that was a good thing then you would do that with the ecu map.
everybody knows that letting unmetered air into the plenum will increase AFR and lean out the burn but the engine is already trying to maintain the 14.7:1 ratio all this is doing is making the ratio higher say 15.5:1 which will increase mpg but will not necessaraly be good for your engine.

is my reasoning OK on this.

This thread makes interesting readin, but it is the links to the patents and drawings and other vacuum relief valves that make it worth a look

I know in is a bike forum, but engine braking is much more important to a biker

I have just ordered one of theses to see what happens when I fit it.

Just got valve today, I will do some standard fuel consumption test over the next week or so and then fit it and see what happens, I am not expo ting much but we will see.

Blimey Dave you kept that quite! How much you pay for it dude? Also be interesting to see what if any a difference it makes. Are you getting an emissions test done to see if that also goes down?

[Davezj]

no steve it is the one in the attachement i mentioned (the cheap one) not an intech one. i am can afford £15 but not £300 on a whim.

just wanted to see what it will if anything.
