Fellow FD owners,

As the title says, I have to pass emissions, the only one I have to conform to is the CO reading, mine was 5 and needs to be 0,5. Would it be an option to put in 2 switches for killing the power to my first rotor's coils and injector?

What would be the downside of this?

The car has a single turbo and running a microtech ltx8, engine is brand new, 150 KM at the most. and has a full 76mm 3" exhaust system, no cats whatsoever. At this moment I cant get her to idle below 1100 rpm.

Would this be an option, or should I go for an electric airpump and alcohol in my tank?

Please advise.

a very interesting proposition...

That wouldn't work in the US. Emissions are read as "parts per million"; the sniffer reads the percentage of emissions. If you shut down half the motor you do not effect your percentages, you just make the engine smaller so to speak. You'll still fail.

Unless the Netherlands reads total emissions as opposed to the percentage of emissions within the exahaust stream it won't work.

 

sorry for the 2 threads, computer was acting up.

I thought of this because my engine was bogging heavily on the test bench over here and turned on 1 rotor, that was the moment that I got within the limitations of the approval

 

damon, your initial observation is probably one mistake that most people make, however, it is not necessarily true

your net emissions will lower, as it is only measured in parts per million, it does not compute engine displacement and create a relationship between the two.

Example, if your engine puts out .90ppm with two rotors, and .45ppm with one rotor, then you might pass....

It's not a sealed vaccum that it's reading the exhaust out of, so it can't measure the net of the exhaust leaving the engine, it's just read in ppm

someone explain why i'm wrong, please!

your best bet would be to not only run on one rotor, but decrease fuel pressure by about 10-20psi

 

Actually, if only one rotor is combusting, the other rotor will just be pumping air into the exhaust stream, diluting the combustion products from the other rotor. However, the shitty idle will probably tip someone off that things aren't right.

Why not just throw on a cat for the test? You might be able to get by, even if there isn't an airpump connected to it.

 

I don't see how that would work. The rotor with its injectors off is still pumping air through the exhaust pipe and the sniffer will recognize this as your dillution percentage being crazy and fail you.

 

Why do people think they can pass emissions with no cat?

 

Just pay the guy off.

 

If you can't idle below 1100 with two rotors, you'll have more trouble with only one rotor. You'll have to raise your idle to keep it running and that will cause more problems.

I would suggest installing at least one catalytic converter, and an airpump is a good idea as well. Smog or not, you might want to have your car tuned so it will idle nicely, unless you've got some sort of port job that you haven't mentioned.

-s-

 

You can "allegedly" unplug the primary injector (2ndary won't kick on at 25mph - am I right?) which will make you run lean and dilute the exhaust like an air pump. Since your engine allready needs a rebuild, you don't have to be so worried. You may get a jackhole tester that wants to fail you but can't so he will refuse to pass you, refund your money and tell you to go somewhere else. I was told this "allegedly" works on pisston motors.

 

skim, what turbo are you running, would it be possible for me to get some screen shots of your settings as I am trying to get my car started but am not sure where to begine. Thanks

goracer his engine is brand new. He doesn't need a new one.
Like someone else said, Can't you just throw the guy a hundred bucks and forget about this whole hastle. Thats what I do and I know a whole bunch of people on here do the same.

 

I have learned, the hard way, of getting an emmisions waiver. If the driver is classified as disabled, and you drive less than 5,000 miles per year, one qualifies for an emission waiver, in Maryland.

I guess the trade off for not walking very well is an FD with less restrictive exaust outflow.

 

That's weird, thought it said he was running on one rotor

Wavor is no good. Those are temporary (one year) and is only given once (At least in CA).

The "alleged" tipping to the friendly smog technician should "not" be discussed in open forum!

 

The waiver lasts as long as one's disability. Maryland grants a disability classification for a limited number of years ( in my case, 2-3 years).

 

Thanks for all the replies, the car needs to pass so that I can drive it around without me having to worry for my insurance and can bring it to Jon to have it tuned.

I unfortunately can pay the guy off, over here the Mot/ test persons get "points" for letting cars through that arent within spec, that can cost these stations a fee. (high one)

MODRX7, send me a PM and I will send you my base maps.

Over here there are only 20 FD's at the most, the most test stations dont even know the brand or type of the car, let alone the type of engine. They wont notice that its running on 1 rotor.

The law states that I dont have to comply (is that right??) with the emissions because I have some sort of 2 stroke engine, this officer thinks I have to comply with only the CO value. These persons spent 1 hour talking on the phone with 4 different people of the same company and 2 said yes, and 2 said no. ??? thats typical Dutch unfortunately.


Would this be worth a try?

 

my inspection has been bad since may. if you have a drive way dont even worry about it. if not pay for one.

 

Rogier,

get the 1100 rpm gremlin out, fit a cat (you can borrow mine if you like) and fit an airpump so the co will go down.

 

Thanks,

Want to work it out, but need someone to work the microtech, John can, but I have to get to Germany then

 

anyone??

 

just an idea
did you try Pim van der Burgt from euro-rotor?
maybe he has some "rx-7 friendly" test-guy

 

why not try it and post up what the results are? an engine will run with only 1 rotor so just make that switch.

 

hahahaahaa rolling of my chair from laughing

if the people at the station are that stupid I would take the car to some other station....

Just get a cat, fit the stock airpump, connect a powerswitch on the airpump, switch it on during smoggtest and voila... passed the test.

I wouldn't run the engine in one rotor, mechanics aren't that stupid and it's not good for the engine
