So have you ever heard about something called a DEF pressure relief valve? It sounds a little convoluted, but it really isn't that hard to wrap your head around. DEF is short for diesel exhaust fluid, a critical fluid in many of today's diesel-powered vehicles. For these engines a DEF pressure relief valve acts like a safety valve. It is designed to prevent the engine with excess pressure by releasing it when they are too high. This is crucial since too much pressure can create leaks and actually shatter the engine.
With that definition in mind, here is how a DEF pressure relief valve actually works. Unlike gasoline engines, diesel engines don't exactly use fuel. This disparity leads to diesel engines generating a greater quantity of noxious emissions that pollutes the environment. Selective Catalytic Reduction (SCR) is a solution to this challenge, and DEF is a special fluid that goes into the exhaust system of an engine. Upon insertion of DEF, it works with the noxious exhaust gases to turn them into nitrogen and water vapor, both environmentally-safe products.
As with any mechanical component, DEF pressure relief valves can sometimes be problematic. A common issue is improper closing of the valve. This can cause DEF fluid to leak out of the system, which is bad news. If the DEF fluid becomes low, it can cause the engine to enter a reduced power mode. That means the engine is going to be getting ready not to run right.
The encouraging news is that many of these issues can be resolved! If this is not the case, it has to be cleaned or even changed. If the valve is not being opened then it may be trapped with dirt and cleaning it will help. However, these problems can easily be avoided with proper valve repairs along with regular maintenance and inspections to ensure your engine operates properly.
Maintenance-wise, maintaining your DEF pressure relief valve comes with a lot of benefits as well. For one, it prevents high pressure from causing damage to your engine and exhaust. In addition, maintaining the valve helps to prevent leaks and low DEF levels, which can reduce engine power and performance.
Last but not the least, selecting a suitable DEF pressure relief valve for your vehicle according to its requirements is very essential. However, there are many different valve types on the market and they function in conjunction with specific engines/DEF systems. Always refer to your owner's manual or consult a professional mechanic when you choose one, to confirm that it is the right one for your vehicle. They can assist you in selecting the best valve that will match your vehicle perfectly.
