For example when to purge during a drive cycle, where to purge intake manifold under vacuum conditions or upstream of compressor during boosted conditions , and how a purge event affects engine performance and emissions. Gamma Technologies has responded to the interest by working with customers to utilize existing modeling components in GT-SUITE to model the evaporative emission control system.
Stand-alone carbon canister test simulations as well as drive cycle simulations of a carbon canister integrated with a fast running engine model FRM in a single model were performed. There are some recent additions to the software that have made modeling this application possible. To protect fuel from splashing out of the vent a slosh valve is provided that automatically closes if liquid splashes against it.
The carbon canister will store the hydrocarbon and only the filtered air will be released. Once the engine is started, it creates a vacuum and will pull the hydrocarbon through the engine, burning them through the normal combustion process. Your email address will not be published. What does a carbon canister do? What happens in the tank?

They said that in order to access the canister they would have to remove the exhaust system. They said the exhaust was rusty and would fall apart. I took the car home. The check engine light did not go on while I drove it home for about 20 minutes.
Would love to hear some advice. From what I understand the charcoal canister is a bit harder to get to on that particular vehicle. You can always try getting an estimate at an independent shop. Independent shops tend to be much cheaper than dealerships. Is it able to screw back on or replaced. And is it safe to drive on. Two years ago August , at , mi my engine line went on.
Only unusual thing to have happened a week or so earlier…after a miles trip, filled gas tank maybe too much and smelled some fuel. But that went away, then later lost gas cap in another fill up.
Replaced next with a new cap next day. Could either of those two events have caused my problem? Does infrequent driving cause EVAP problems? Yes, in fact either event could have given you an EVAP code. Driving with the gas cap off is a quick way to get a check engine light, and so is topping off at the gas station. When you top off, there is a chance you could get some fuel into the EVAP system and possibly the charcoal canister, which could trigger a code.
How frequently do you drive? Do you smell fuel in the engine bay or near the fuel tank? Not smelling fuel now. Did notice smell briefly when I may have put too much in the tank. I did not notice the light until some days after I replaced the cap, which I did the day after I lost it. By the way, the mechanic who tested the system reset the computer to see if it would go back on, which it did…not immediately, but within a few miles. Also, I leave it in the driveway which gets very hot this time of year.
Why would infrequent driving cause this problem? You may need a new carbon canister if it was saturated with fuel from topping off, I am not sure. You could try an evap leak tester to see if you can pinpoint the problem. Perhaps there is just a leak in a hose.
