def pressure relief valve

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.

How def pressure relief valves work in diesel engines

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.
