denatured alcohol to pass CA smog? fact or fiction? FACT!
 
whats up ht, okay so i have a 91' civic hatch thats bar'd for a 91' B18A1. i currently have a 98' jdm B18B motor in there & i reused my allllll of my obd0 components on the new longblock.
The B18B has bad rings, it smokes on coldstarts and heavy acceleration. I also didnt rewire my fan switch so the radiator fan wasnt on. This is how i cheated the smog:

91' civic hatch bar'd for 91' B18A1
jdm B18B obd0 configured
timing set @ 16 degrees
stock 1.5L airbox w/ k&n filter
new random unknown brand ca compliant cat i got from a muffler shop
hedman header ( didnt even ask for the carb sticker )

i drove my car around for about an hour before hand & ran it suuuper empty, put 2 gallons of 87 octane & poured in 1 gallon of denatured alcohol while it was running. It didnt affect the idle at all, didnt smoke, the car didnt even seem to notice, but you could definitely feel a power decrease. I drove it 15 min to the smog shop in third gear & let it idle outside.

15 MPH:
max / meas
HC: 127 / 46
CO: .79 / .12
NO: 825 / 801

i checked the temp of the car after the 15 MPh test and it was overheating, the needle was halfway between NOT and max temp. i asked him to bring out the huge air circulator fans and throw it infront, it did alot better.

25 MPH
max / meas
HC: 101 / 23
CO: .68 / .08
NO: 764 / 70

IT WORKED! i passed and immediatly after leaving the smog place i went to the gas station and filled it up to try and dilute the alcohol as much as i could. Hope this helps someone.

if you saw the way it burns oil you'd know it would fail too. Last week it was blowing out so much smoke it killed a semi-new o2 sensor in a week, i replaced it yesterday.

You have a B18B1 that has bad rings and overheats and you are worried about it passing smog?

This thread is misleading information because the smog test has different fields. NOx is not positively affected by alcohol, only hydrocarbons and CO. Get the mixture of alcohol wrong and you could fail NOx if your HC drops too low and you start running too lean.

Alcohol works for some, but not all. If a car like a Dodge with a 318 or 360 is failing for what they typically fail for which is NOx and you suggest to them that they run alcohol, their NOx numbers will get worse and they'll risk damage to their catalytic converters. The risks of everyone running alcohol are too great because not everyone is an emissions (smog) expert and using it inappropriately could result in damage of catalysts, oxygen sensors, and even engines; this is why I never suggest it to anyone.

You'd be surprised how many smoky cars pass and how many seemingly clean cars fail.

And yet you still want to run this piece of shit?

im borrowing this engine to get my tags because thats what its bar'd for. once i get my tags, i can reswap it with the itr swap waiting in my garage & im good for 2 years. I shouldve tried to smog it without the alcohol, but i didnt because im impatient. i found a lot of mixed opionions so i decided to try it for myself & it worked. why not add another good testimonial for someone that could be skeptical on trying it themselves?

Wouldn't it be grand if more people beat the system and continued to pollute the air using tricks like this? Great info :thumbup:

so you're doing all this swap labor just for tags?

i can't believe the trouble some of you go to in order to keep old cars going

Re: denatured alcohol to pass CA smog? fact or fiction? FACT!
 
yess i am, this situation doesnt pertain to only older cars. any one that swapped a bar'd car with something else has to pull that engine out, swap, then reswap. so i guess im the type of person that loves their car enough to do something consuming as shit like this lol

or you COULD have just properly swapped the b18c5 with all necessary smog equipment and have it bar'd for that swap.

buuuut i didnt feel like sourcing out a clean usdm b18c5, so i got a clean b18c itr which was 1000 times easier to find

I came in here to say that alcohol will increase NOx, but it's already been said. If we get back on topic, take a look at the OP's test numbers; he barely snuck by on the 15mph test with NOx, he was just 24ppm away from failing which is a very very very small margin. If intake air temp was just 2 lower, it would've likely failed on NOx and his HC/CO numbers would've been down a few points.
