Chevy CK Pickup EGR Valves & Parts

EGR stands for exhaust gas recirculation. It’s the emissions reduction technique that has been in common use among automakers since the 1970s. The main component of the system is the valve that allows the gas from the exhaust system to get back into the intake manifold. By adding a portion of burnt fumes, which act as an inert gas, to the combustion chamber, the system reduces the amount of formed NOx. Besides, the addition of inert gas to the chamber allows for an increase in compression ratio and generally offers more favorable conditions for combustion. Also, it reduces the amount of incomplete combustion by-products, as they get eliminated during the recurrent cycle.

The first generation of EGR systems was purely mechanical, with the by-pass valve opened by the vacuum in the intake. Such a scheme, however, caused the engine output degradation, which is why it was replaced by electronically managed systems controlled by the ECU. Which one is in your CK depends on its generation and the engine installed. But in any case, our Chevy CK Pickup EGR valves & components inventory can offer you the right and affordable solution to address all the possible issues.
