The canister is an environmentally friendly device that can absorb volatile gasoline vapors in the fuel tank, and then when certain conditions, the ECU opens the canister solenoid valve allows the gasoline vapors to enter the engine combustion. So in the end it played a big role in the car? Canister if there are problems which can cause malfunction of the vehicle it? Today I come to look at together.

Canister shelf life

A canister adsorbing fuel particles pass through the inside of the activated carbon, the next car is normally no need to replace the canister life. But if three things happen usually a canister should be replaced.

1, refueling too full, since the fuel vapor in the fuel tank mounted above the valve, when the solenoid valve opens the canister will be sucked into the carbon gasoline tank.

2, the canister is mounted in the vehicle most portion of the tank near the bottom of the vehicle, due to the harsh environment of the chassis, the vent hole housing will rupture or water.

3, active carbon or an internal filter cotton quality problems, leading to a period of time three holes clogged, resulting in excessive tank pressure.

Canister failure caused the problem

1, fuel can not start too full

Many owners will encounter too full tank with engine start led to difficult problems, it is likely that gasoline evaporative control system canister where there is a problem. A canister solenoid valve is opened, resulting in gasoline vapor within the fuel tank into the intake manifold of all, so that the computer detects the mixer can not start too thick. Normally closed solenoid valves could cause the tank gasoline vapor saturated carbon, excess gasoline vapors directly scattered into the atmosphere, problems such as strong car gasoline.

2, canister failure spontaneous combustion

As domestic fuel quality is not high, fuel vapor impurities, granular activated carbon canister easy to plug holes after prolonged use, plug the hole so that fuel vapor gas discharge nowhere, resulting in excessive pressure exhaust gas tank, causing the tank riveted joints oil or other interface cracks, caused by oil spills, prone to spontaneous combustion accident when confronted with a spark. Therefore, under normal circumstances, every two years to conduct an inspection of the canister, the canister into the oil and to exclude blockage risks. And long-term raise low quality fuel oil users should shorten the inspection intervals.

It-yourself repair clogged canister

1, open the canister, the canister lid cut

2, pour out the old activated carbon.

3, the dry filter paper jam or replaced.

4, into the activated carbon (charcoal you can go to sell fish in the market to buy a bag of 25 yuan.), Drilled in the side of the canister, by way of self-tapping screws, put back the lid, fill some gaps in the glue in, then screwing, until the glue dries, can loading.

My Tip: regularly check it not only reduces the probability of failure of the oil, but also be able to take preventive measures due to accidents caused by oil and gas leak.
