Toyota Innova Owners & Discussions [continued 3]

[MrQ5]

Naka VNT na ba yung innova mo, in other forum turbo VGT or VNT will lit your CEL check engine light.
Mine was block i think more than a year. Mas matagal umitim yung oil at konting improvement sa acceleration.
Saka soot reentering intake di maganda sa maraming study, saka nag air filter pa tayo tapos sa soot ipapasok lang ulit ng egr.
Mas maganda egr deleting na gawin mo, para kung malusaw man plate na ginamit mo di mapupunta sa combustion chamber.
Been planning this kaya lang di pa nagagawa, btw my plates are stainless alloy I think scrap from aircraft materials or supply.

i don't want the soot to re-enter my engine again and clog my injectors in the long run. lalo na knowing that the EGR only operates at constant speed and close all the time.

but why did the manufacturer place it there in the first place, i wonder...

To comply with emission standards of some countries.

To comply with emission standards of some countries.

so i suppose it's not a very good idea to tinker with it..
mine has been in service since 2005.. and after almost 95K, i see no manifestation of dirty injector syndrome.. i suppose it takes quite some more time for the dirt to build up...
does the TS have first-hand information on this, or is he just echoing someone else's story?
anyone out there who can help us understand more...?

hindi pa VNT turbo ng innova ko paps, 4th gen ata yung mga naka VNT na. 3rd gen yung sakin.

ikaw mismo nag fabricate nung blanking plates? san ka nagpa block? salamat.

[vvti2.0]

Wala naman atang innova ang naka VNT.

i just want a cleaner engine sir, that's all.

There's a thread here about EGR blanking. A lot of topics online regarding the benefits of EGR blanking.

Ako lang diy may scrap metal stainless alloy sa likod bahay <3mm, trace the metal gasket sa plate na gagamitin mo cut /drill hole, saken di maganda kinalabasanng cut kasi grinder lang pang finish ko pero ok lang di naman makita kasi naka-sandwhich sa gasket at egr pipe.
Pag diy mas maganda bring the gasket to machine shop, sila na bahala gumawa, >5mm metal pag egr pipe delete.
Mahirap lang kapain yung unlock ng isang sensor malapit sa exhaust ng egr pipe, tatama kasi tools pag di ito tinanggal.

Egr was there to reduce NOx in compliance with environmental restrictions by reducing the combustion temp doing it by recirculating exhaust gas (cheap source of inert gas) into combustion chamber. But by doing this, the soot and sulfur(in acid form) is also introduce in the intake and not good for internals. This what I had read about soot and egr, iirc.

Our Innova is gasoline; But one of our rides is diesel. And so, I had it EGR-blocked. Improvement in performance as 100% of the exhaust is directly fed to the turbine of the turbo... Plus, the engine chamber is "cleaner". But (max at idle), NOX is there....
