EGR - Exhaust Gas Recirculation Valve. This is the element that diverts some of the exhaust gases to the intake manifold. A large amount of car exhaust gas is released into the environment, so the EGR valve plays an important role in reducing emissions. EGR technology promotes more efficient and faster operation of the intake manifold, which is beneficial at low ambient temperatures and for toxic emissions.
Operation of the EGR valve
EGR valves protect the environment by recycling exhaust gases. The EGR valve determines the amount of exhaust gas to be passed into the manifold based on engine speed, temperature and other parameters. This system connects the exhaust and intake manifolds, thus transferring part of the exhaust gas to the intake manifold. This principle results in efficient combustion of the gases, reduced exhaust pollution and lower fuel consumption.
When should you repair the EGR valve?
In almost all cases, the EGR valve is not repaired but replaced. The causes of EGR failure can be varied: the valve is stuck in the open or closed position, which causes deposits to form. The use of faulty fuel, the ingress of lubricants into the combustion chamber, and the valve may also burn out due to an improperly formed air-fuel mixture where the fuel burns in the exhaust manifold.
A malfunctioning EGR system burns fuel poorly and produces more soot, and can also damage the DPF FAP filter. To prevent EGR valve failure, it is recommended to regularly check and tighten the timing belts, as loosening them can lead to valve timing and rich mixture formation. If the mixture is too rich or too lean, the fuel will continue to burn in the exhaust system, leading to EGR valve failure. To avoid this, it is also important to change the air filter on time and make sure that the fuel injectors are not blocked. Repairs to the EGR valve can be a major loss, so it is essential to have your car checked and serviced regularly and to replace parts regularly.
