Do You Know About EGR Valve Inside The Used Chevrolet Orlando LTZ For Sale
Modern cars are equipped with an EGR (Exhaust Gas Recirculation) valve. A buyer of used Chevrolet Orlando ltz for sale should know about that such as what is the EGR valve? And how does it work? When should it be replaced? And what is its cost? because for secure and easy drives on different terrains such type of awareness is necessary.
What and How
The EGR is a valve that has the function of recirculating a part of the exhaust gas produced by the engine to send them back to the intake manifold. In reality, only a small part of these gases are recovered from the EGR valve, it goes from a minimum percentage to the top one, just enough to cool the temperature in the cylinders and therefore that of the exhaust, so that they are lowered emissions of nitrogen oxides (NOx). The purpose of the EGR valve, therefore, is to reduce environmental pollution produced by exhaust gases. The EGR Valve takes a part of the exhaust gases, which pass through an exchanger to lower the temperature and then be returned to the intake manifold. In essence, the recovered gases (exhausted, since they are free of oxygen) will be mixed with the air drawn in by the engine necessary for combustion.
Under Control
The work is carried out by the EGR group under the control of the control unit, which manages the opening and closing of the EGR valve. The EGR group includes one or, in some cases, two EGR valves, other valves, cables and, sometimes, even a small dedicated engine. The most frequent problem of the EGR valve is the accumulation of dirt, precisely because of the continuous passage of the exhaust gases. The problem that occurs especially on diesel cars that travel short distances, often without reaching the operating temperature. The EGR valve malfunction is often indicated by the yellow ‘engine failure check’ warning light. To solve the problems of the EGR valve it is possible to clean it with specific chemical products, but it is not always sufficient: in these cases replacement is necessary.
Undesirable Practice
It is also possible to exclude the work of the EGR valve, but it is an inappropriate practice, which among other things involves the increase of nitrogen oxide emissions. A used car buyer who has the desire to pay the Chevrolet Orlando ltz price should know that how to put their hands in the bonnet of their car; so, only those who have some experience in the field can personally clean the EGR valve. Here's how to do it: the first step is to detach the suction hose, then we will proceed to clean the deposits with a specific product. Afterward, the EGR valve (fixed with screws) and cleaned with products should be detached. It is crucial to check that the gasket on the flange of the EGR valve is still in good condition, otherwise, it should be replaced.
