Pure Water In Def Tank

Pure water also known as purified water is water from a source that has removed all impurities.

Pure water in def tank. Diesel exhaust fluid def is 32 5 solution of high purity urea in de mineralized water that is used with the selective catalytic reduction system scr to reduce emissions of nitrogen oxides nox from the exhaust systems of diesel vehicles in the usa. The engine will start without a problem and the tank. The catalytic converter uses various metallics to clean the pollutants further before exhaust exits the tailpipe. Throw in a gallon or two of water to fool the system so i could get another 100 miles to my next fuel stop with pump def.

I ve been that low before but this time i made the mistake of shutting off the engine. Urea is technically derived from a byproduct of urine but for mass production purposes it is synthetically made. Def available at most service stations for 6 to 10 per gallon is a fluid consisting of urea and deionized water in a 1 2 solution. The fluid needs to remain pure for it to work correctly.

From a strictly chemical disposition def is a mixture of 67 5 deionized water and 32 5 urea. The short answer is that def or diesel exhaust fluid is an important component in keeping heavy duty trucks and machinery operating within federal emission guidelines. Def is mostly water about 2 3. Def is stable colorless and odorless and meets accepted international standards for purity and composition.

Those who turn a def ear face harsh penalties. The exhaust gas that gets through the filter is sprayed with def which is 67 5 purified water and 32 5 urea and goes into the catalytic converter. If def freezes in the vehicle do not put any additives in the tank to help it melt. Starting in 2010 def became a major need for companies using medium and heavy duty diesel vehicles.

It is a nontoxic solution of 67 5 purified water and 32 5 urea. Urea is a compound in nitrogen that turns to ammonia when heated and is used in a variety of industries. What def is at a chemical level is a combination of deionized water and urea that transform harmful nitrous oxide emissions into harmless water and gas. Diesel exhaust fluid def is a clear non hazardous liquid.

When injected into hot exhaust as a fine mist and passed over a catalyst def helps convert nox into nitrogen gas and water vapor. Distilled water is the most common form of pure water.
