The Emission Control System (EVAP) controls the output of noxious and potentially harmful gases generated by your vehicle’s internal combustion engine. Before cars were required to have EVAP systems, the hydrocarbon fumes from burning the gasoline would be released straight into the atmosphere – not an ideal situation.
EVAP systems regulate hydrocarbons, carbon monoxide, and oxides of nitrogen and sulfur from the engine exhaust, the crankcase, and the fuel tank/carburetor. Since there are lots of areas in the engine that the EVAP regulates, there are lots of ways that it can go wrong.
At Jay’s Garage, we take emission control very seriously because we always place a premium on having Portland’s most environmentally-friendly car repair and tune-up shop in Portland. That’s why we supply our own bio diesel on site so that our customers have access to a gas source which is more renewable and releases fewer toxins into the atmosphere.
The EVAP doesn’t break down too often, but when it does, it’s very serious. Not only is your car a potential pollution and health hazard, but you won’t pass any DEQ tests until you have it fixed. And since gasoline releases fumes constantly, your car can be discharging pollutants all day – even when you’re not driving it.
If your EVAP system is malfunctioning, the check engine light on your dashboard will light up. This is the sign that you should have your car inspected by a professional. Why not take it to the Portland car tune-up specialists at Jay’s Garage?
Fixing your EVAP System
When you bring your vehicle into Jay’s Garage to have your EVAP system fixed, we’ll inspect each of the EVAP’s three major components:
- Fuel Tank- Built with space at the top because high temperatures cause the fuel to expand. The added space minimizes the risk of your tank leaking on an exceptionally hot day.
- Gas Cap- Completely sealed to prevent any leakage. If your gas cap becomes unscrewed or damaged to the point where vapors can escape, it will trigger your check engine light and need to be addressed.
- Liquid-Vapor Separator- Prevents gasoline from entering the EVAP canister through the vent line. Gasoline overloads the canister’s ability to store fuel vapors, so you want to make sure that no vent lines become clogged or crimped.
After thoroughly investigating your system and determining what the problem area is, Jay’s Garage will repair your vehicle in a prompt and professional manner.
Also, emission control problems are always best-resolved in a proactive rather than reactive manner. So next time you bring you car into Jay’s Garage for a routine tire rotation, oil change or brakes check, have us take a quick peak at your EVAP as well. It’ll save you time and money down the road.
