EGR valve Megane IDE![]() Fortunately, you can remove the valve, clean it and go on. It can also be sealed so as not to brudził, but in this particular engine, this is not the best solution since the presence of gas in the mixture, not only diminishes but a mixture lowers the combustion temperature. If there is no gas in place of the inert gas is collected additional air and the computer on the basis of the oxygen sensor readings artificially increases the dose of fuel. In addition, increasing resistance to suction which also reduces the efficiency of the unit. Despite this, most blind EGR intake for fear of an unpleasant surprise while driving. In use, the only difference is a bit violent reaction to the gas pedal in the 1700-3800 rev / min, and perhaps slightly less economical. However, according to PC Data 300 miles route difference was minimal. (Smooth running at a speed of about 70-80 mph, which is within the error limits. The EGR valve is attached only under certain conditions:
EGR valve shut off in case of an error reading data from:
Dissasembly of EGR valve The operation is quite simple, but it is best performed on a cold engine, as it is possible burns from hot engine parts Disconnect the battery, then remove the plug from the valve. Then unscrew the two screws securing the collector. Then remove the pliers clamp connecting the exhaust intake valve. Valve without problems comes up. To clean the valve must first soak the lower part of the middle penetrating. Then move the valve stem penetrating rinsing agent. After some time, the valve starts to operate easily. The valve is a fairly permanent feature outside the typical dirt and rarely causes damage to the potentiometer. In order to verify the correct operation of the valve can be connected to the 12V between terminals 4 and 6 Installation is carried out in the reverse order Wiring diagram![]() 2 - mass potentiometer 3 - the power of the potentiometer 4 - valve ground 6 - valve power supply Potentiometer resistance path around 5 k output Load potentiometer 150Ω-5kΩ valve 6 Ω resistance EGR valve blockage![]() ![]() ![]() ![]() |
