What does DEF do inside a diesel engine, and how does DEF work to reduce air pollution? When injected into the exhaust stream of the engine, DEF undergoes a chemical reaction with nitrogen oxides (NOx) present in the exhaust gases. This reaction takes place within the SCR catalyst, breaking...
Diesel exhaust fluid is a new approach to global emissions reduction. Learn more about DEF and what it does for your diesel engine.
Diesel Exhaust Fluid (DEF) is the reactant necessary for the Selective Catalyst Reduction System (SCR system) function. DEF is required for the proper after-treatment operation of your emissions system. It is a carefully blended aqueous urea solution of 30% high-purity urea and 70% deionized w...
Click here to read about after-treatment of diesel exhaust fluid (DEF) also known as AdBlue. We take a look at what diesel exhaust fluid is and why it’s needed.
The DEF tank is often located right next to the diesel tank. You can tell the difference by looking at the color of the caps: Typically, the DEF tank has a blue cap, and the diesel tank has a green cap. Always double check to make sure you put the proper fluid inside the proper ...
But, what exactly is diesel high idle, and when should you use the high idle feature? Is idling bad for the engine? Do you need to let a diesel engine idle on cold mornings? Does idling a diesel engine bring it up to operating temperature? The answer may surprise you!
However, we do have some first-hand experience with DEF as it has been a feature of diesel-powered Class B+ rentals we’ve had when RVing overseas. How Does a DEF System Work? DEF is one component of a larger, specialized emissions control system that’s installed in newer diesel-...
“More maintenance is required on a diesel with the DEF fluid that needs to be added to the truck about every 2,000 to 3,000 miles,” said Brian Tabel, executive director of marketing for Isuzu Commercial Truck of America. “The diesel particulate filter (DPF) also needs to be serviced ...
