VW Beetle & Harabas passed the emission test, u know how

[Doc Diesel]

ha ha....adjustment on the a/f mixture was almost correct but not quite.

after the 1st test, my dad asked our tech. to bring back the vehicles to the PETC and ask how can we let the vehicles pass. Without any hesitation, the MVECT [PETC technician] asked our tech. to bring the vehicles at the backside of the testing center.

another man came following them with a long flat screw driver and a small barbecue stick. and this is what he did:

1. Screw IN full adjustment of air screw.
2. Screw IN full adjustment of idling with a stick still pushing it in, making the engine idle at around 1,500 to 2,000 rpm

after that, the test and what do you know, scores to die for. and that without any parts changed nor any engine modifications or tune up.

and all the while I thought the PETC will be an angel for a cleaner air.

question doc,

but screwing in the air correction screw would make the engine go rich diba?

[woodfire]

..... so in effect, we are just fooling ourselves about this so called "cleas air act." the best is to be able to REGULARLY and STRICTLY randomly check all these buses, jeepneys, 2-stroke tricycles, and other vehicles. WALA DAPAT LAGAYAN!

Ang problema sa bansa natin ay hindi yung batas pero yung pag-implement at enforcement ng batas! :evil:

kami naman, sa bicutan test center, yung tester mismo na nagsabi na sila na bahala....after some mods in the "results"....viola! passed na sya!!!....di ko lang alam kung ano binigay ng dad ko.....

Ganyan din sa mga U.S. smog centers. Madaming mga small time talyer sa paligid tapos dun mo dadalhin kung failed ka. I-aadjust nila para pumasa ka then after the test babalik ka sa kanila to return your engine to its former state.

i believe it will go lean as it increases the air goin to the chamber.

[HBOY]

tama sila dun.. adjust to go lean..... sakal sya.. pagkatapos ng test.. ibalik mo.....though you just fooled yourself in to thinking that your car is actually contributes to the clean air act...ehehe

[bustmybrain]

is there a way to do this with a fuel injected engine?

sir its easy to point fingers...pero if you read all the post in this thread you would be amazed kung ilan ang nag-iisip na DAYA or AREGLO na solution instead of having their cars properly conditioned (nakakalamang sila).

IMO, hindi na enforcer ang problema - kasi nakikiride na ang mga pinoy sa mga gagong enforcers .... kaya pati mamamayang Pilipino e kasama na sa problema....sakit na ng Lipunan

Kung magbabago lang sana tayo mag-isip ng nasasangayon sa tamang paraan....tsk, tsk, tsk!

just my 2 cents. peace!

some injected engines have also A/F adjustment screw.
