This mechanism creates problems related to exhaust gas pressure and for this reason it is necessary to introduce a throttle body that acts as a "plug" and increases the gas pressure. But how does a dual EGR valve work? Basically, two different EGR valves are placed inside the exhaust circuit, which requires a double recirculation of air. One such technique is the use of a dual EGR valve. To keep up with these laws, automakers are striving to find simple, easy-to-implement solutions to make their fleets greener. How does the dual EGR valve work?ĭue to intensifying climate change, exhaust emission limits are becoming stricter every year. #WHAT DOES A EGV VALVE DO SERIES#The entire operation is managed by the control unit that monitors the quality of the gases through a series of digital sensors. The valve opens and closes to adjust the amount of exhaust gas the engine needs to receive. To understand how the EGR valve works, just consider how the EGR valve works. The EGR valve is the most common valve, as it has been used for decades. We have discussed what happens when the EGR valve is removed before and the consequences can be far from positive. This is an urban legend because the EGR valve in no way reduces the car's engine power. Many motorists believe that the operation of the EGR valve reduces the performance of their car. By means of a series of sensors located in the exhaust manifold, the control unit regulates the opening or closing of the valve, thus regulating the air flow to the engine. The EGR valve is always controlled by a specific section of the control unit. This process makes it possible to reduce the percentage of pollutants, which is an increasingly difficult parameter for car manufacturers to meet. In this way, the air that reaches the engine comes partly from the radiator and partly from the exhaust system. without oxygen, and reintroduces them into the engine's intake manifold. The EGR valve takes some of the exhaust gases, i.e. You don't need a degree in mechanical engineering to understand how the EGR valve works. It is an acronym for " Exhaust Gas Recirculation". However, to fully understand what an EGR valve is, it is necessary to explain what EGR stands for. Electronic EGR valves tend to be more fragile and more susceptible to gas buildup. Some cars have a mechanical EGR valve, actuated by the gas flow, while others have an electronic one. This mechanism allows complete combustion of the fuel and a reduction in pollutants, including nitrogen oxide. This valve reintroduces a part of the exhaust gases into the engine (between 5% and 15%). The EGR valve is designed to reduce the emission level of most modern vehicles.
