hey again, i have a 1.3 carb'd samurai that just failed aircare  




The term "aircare"  sounds so ....... nice :P Maybe the Canadian government just has a way of making the dreaded SMOG TEST a civic duty ;)

For God sake take the easy way out.  Go to your mechanic and ask him for the name of a mechanic who will pass the aircare certification thingy no matter what.  In toronto, there is an entire underground economy based on this provinces DriveClean program.  I couldn't certify my vehicle without spending at least a grand on repairs to the "pollution control devices", but an extra hundred bucks to Oman the Shady mechanic, and I'm set for at least two more years! ;D

Try it.  Black market is good!   ;)Black market is your friend!



unless he asks the wrong mechanic and the guy turns him in..then hes in a steep pile of sh%t

i paid some dude to pass the hooptie last time..but i dont know if id go ASKING lol

that don't work here in bc, as the test facilities are government run. but if you can prove you spent two hundred dollars or more trying to fix the problem you can get a conditional pass. so finding someone to write you up a fake bill for $200+ is the shady trick. luckily i passed last week so i'm good for two more years :)

it burns maybe a liter of oil every month or two


The oil burning could be part of the prob. How many miles per liter of oil? How many miles on the engine?

On the cheap, check your plugs are clean and gapped properly, check the PCV valve is working & the EGR isn't plugged. Check your compression. (Oil that doesn't leak is going past rings, being pulled thru a stuck PVC, or is getting past valve guides... usually.) If it's close to passing, using a heavier oil can sometimes sneak one thru. (Straight 30 or 40W... drained after inspection.)

...just a thought...

the oil consumption is pretty minimal... more if i high rev tune it
compression is good, the 4th cylinder is at 135, the rest are 145-150
plugs are gapped fine

i retarded the timing by like 8 or 10 degreees today, so it burns pretty much all the gas it gets, but pings on hills, so ill take it in like that tomorrow, and re adjust it halfway to where it was if it does pass

    I used to get my old Toyota Truck to pass by unplugging 2 or 3 vacuum lines and letting it lean out. My Sammy has bad rings and the heavier oil trick worked for me. I used Castrol 20W-50 and a pint of CD2.

I tried to pass my 92 kick one time and it faile dmiserably.  Then we dropped the transmission into 2nd gear (auto) and ran it up and down the street a couple hundred times.  Getting the enigne nice and hot certainly helped.  Just a suggestion.

ok, so the timing is normally at 10deg btdc
i adjusted it to 0deg for my second time through
guess what? it FAILED! not as bad though, everything improved

here are my original numbers
Driving test| Max Allowed|My Reading|Avg Reading
HC                           280                194             46
CO                          2.67                3.80            0.40
NOx                    3600               215             1072  

here are my new numbers
Driving test| Max Allowed|My Reading|Avg Reading
HC               280                166             46
CO             2.67                3.59            0.40
NOx            3600               190             1072  

im too lazy to type up the idle numbers, same story though, they passed both times, and improved the 2nd time

any new ideas? ??? i heard methyl hydrate might work

anyone??? im mainly interested in this methyl hydrate idea, cause the sami runs fine already, and gets decent gas mileage with low oil consumption

thanks, Andrew

Run your gas tank low, add a gallon or 2
of methanol or some other alcohol for
automotive use, and test it, then fill the
tank with your favorite gasoline and wait
for next Air Care test,

Enjoy

I haven't heard of that one before. Will that drop his CO output?

Alcohol is a much cleaner burning fuel,
as well as it takes more of it to burn
in an ideal mixture, so it effectively leans
the mixture, and produces less of everything

I'd run straight Ethanol or Methanol if I could
find a gas station that had these for Flexable/
alternative fuel vehicles.

Makes sense.

Will it run on straight alcohol? I know you'd have less power, but I wonder about getting the engine started. Hmm... maybe a dual fuel system? Interesting.

From the results he's getting, it does sound like his Cat isn't working. (If it was, his NOX might be higher.)

woohooooo, alrighty
it passed ;)
i put 10bucks of premium gas, plus half a liter of methyl hydrate, mostof my numbers were cut in half
the NOx raised a little, but still below average
the aircare lady said she could smell it, but they dont care how you pass
i dont know if it was the timing, the methyl hydrate or both, but it seemed even more gutless than normal
oh ya, apparently that stuff dries out the seals in your carb if you run it on a regular basis, so be careful

Andrew :D

You bring up a few points, you don't get less power
from running on alcohol, you get less MPG as it takes
more alcohol than gasoline to get a stoichiometric mixture,
there is a table on the MegaSquirt EFI Site that shows these
ratio mixtures

http://www.megasquirt.info/manual/mtune.htm

If Methanol gave less power, you would be hard
pressed to find drag racers using it, but that
is the fuel of choice in the faster classes, it
also allows compresion ratios of 16:1 which is
about double your average street engine CR

If we really wanted to get good milage we would
be running high CR engines and high RON fuels, but
I guess the high CR causes high NOX levels in the
exhaust too, I don't know if this is a factor with
alcohol as a motor fuel, but it is with gasoline.
