EGR valve

Land Rover AFRICA Magazine - - TECHNICAL -

What is the func­tion of the EGR valve and when should it be re­placed? I read about own­ers blank­ing/ re­mov­ing it.

– Lam­brecht My­burgh Ed – The EGR ( Ex­haust Gas Reg­u­la­tor or Ex­haust Gas Re­cir­cu­la­tion valve) di­verts some of the ex­haust gasses pro­duced by the en­gine back to the in­take of the com­bus­tion cham­ber where the fuel is burned. The pur­pose of the valve is to al­low bet­ter emis­sion for stricter en­vi­ron­men­tal con­trols. When an EGR valve stops work­ing, the valve is usu­ally clogged by car­bon caused by short dis­tance driv­ing and cold stop/ starts. The symp­toms are higher fuel con­sump­tion and loss of power. In South Africa it is not nec­es­sary to re­place this unit and there are blank off kits avail­able which helps cleaner air into the in­take cham­ber.
