Jeep Liberty EGR Valve

The main purpose of having your engine equipped with Jeep Liberty EGR valve is to achieve the best fuel economy your engine assembly could possibly deliver. EGR or exhaust gas recirculation valves takes focus on handling and manipulating the produced nitrogen oxide and nitrogen dioxide (NOx) gas compounds as your engine burns fuel. Strategically located right at the intake manifold, the part is designed to open a passageway where fuel exhaust gases could flow back into the engine. Aiming to reduce engine temperatures, your EGR valve is involved in limiting the heat produced by your engine’s continuous fuel combustion operations by using denser and colder air which is then mixed with the injected amount of fuel to produce an atomized air-fuel mixture. When your engine is cold, the valve remains closed to allow heat build-up which helps maintain ideal working temperatures under cold seasons of weather of driving conditions. The valve is only opened when your engine has already warmed up and runs at part throttle levels.

To improve fuel efficiency, EGR valve constructions are typically designed to reduce throttling losses, heat rejection, and chemical dissociation. To reduce throttling losses, the valve causes the throttle plate to be further opened for gas flow so inlet manifold pressure will increase. By reducing the levels of produced NOx compound gases, the part helps reduce the peak combustion temperature so the thermal energy managed and eliminated by your engine cooling systems will significantly cut down. In a way, the valve reduces chemical dissociation in limiting NOx formation which means more usable or sensible levels of thermal energy will be produced which is then used to operate most of active engine components like electronic sensors.

Poor overall drivability is a clear indication of damaged Jeep Liberty EGR valve. At varying engine speeds, experiencing no change in throttle position with possible overheating means that you need to immediately have your Jeep Liberty ride submitted to the expertise of a qualified service technician to earn accurate diagnostics on your actual engine problem. Such will be followed up by timely and necessary repairs, adjustments or EGR valve replacements to resume smooth and fuel efficient engine performance.

Cleaning your stock Jeep Liberty EGR are valve is generally not recommended or it could actually do more harm than good. Cleaning the valve could actually result to forcing harmful contaminants to your engine compartment which and damage the EGR diaphragm. Manufacturers recommend having the part replaced after it has already given 50,000 miles of service for preventive maintenance. Waiting for the valve to fail before having it replaced could only worsen your engine problems so sticking to the manufacturer’s maintenance specifications keeps you from dealing with expensive repairs brought by EGR failure hassles.
