Common EGR valve failures
Exhaust gas recirculation (EGR) valves play a critical role in modern engine management, helping to reduce emissions and improve efficiency. According to SMP Europe Engineering Manager, Nicholas Tideswell, in the aftermarket, replacement EGR valves can vary in quality. He notes that such variations can lead to less-than-optimal vehicle performance, increased fuel consumption, and the need for more frequent repairs.
As an engine management specialist, we have dedicated years of development to overcoming these challenges with our Intermotor range of EGR valves.
Common EGR valve failures are caused by carbon deposits built up over time within the valve, preventing it from closing properly. This leads to an excess of exhaust gases being recirculated, resulting in rough idling, hesitation and poor engine performance.
Another common failure is a faulty diaphragm or actuator, which prevents the valve from opening, stopping the recirculation of exhaust gases. This can cause an increase in combustion temperatures, leading to engine knocking and excessive nitrogen oxide emissions.
What indicates EGR failure?
The key signs of EGR valve failure include difficulty starting the engine, poor or erratic running of the vehicle, a noticeable loss of power and increased fuel consumption.
By recognising the limitations of existing aftermarket EGR valves, our engineering team embarked on a mission to develop a superior solution. Extensive research revealed that some aftermarket alternatives had unreliable or missing electronic components, making them prone to failure – and increased replacement frequency.
To combat this, we designed a custom Printed Circuit Board (PCB) to replace the inadequate electronics found in other products. This advanced PCB, developed and manufactured in our facility in the UK promises reliability, precision and longevity.
Key benefits of our Intermotor EGR valve range include an increase in fuel efficiency and vehicle performance, thanks to precision engineering and a robust design. The range is built to withstand corrosion, contamination and extreme temperatures. Plus, the range is rigorously tested in our UK facility and validated onvehicle to guarantee a slick fit and seamless operation.
