what does adblue do to a diesel engine?
5677
AdBlue is the trade name for a type of diesel exhaust fluid. It's a mixture of urea and deionised water that's stored in a separate tank from the car's fuel. When the car's engine is running, tiny amounts of AdBlue are squirted onto the exhaust gas produced, turning the NOx into nitrogen and water.

Volkswagen uses the SCR system in its diesel vehicles. This system uses AdBlue® to eliminate nitrogen oxides from exhaust fumes.

Petrol exhausts are hotter than diesels. Petrol engines emit more carbon monoxide than diesels. Diesels emit more oxides of nitrogen than petrol engines. Adblue, formaldehyde uses the dissolved ammonia to convert nitrogen oxides into nitrogen and water.

While there are different names for AdBlue®, such as Bluedef, BlueTec and so forth, all mixes should contain the same solution of 32.5% urea and 67.5% de-ionised water. The German Association of the Automotive Industry's AdBlue® marque can be confidently relied upon to meet these requirements, while others may not.

AdBlue should ideally be stored within a temperature range between 0 and 30°C, and kept protected from direct sunlight. It should be properly sealed when it is not being used. It is possible for AdBlue to freeze at -11°C, so it is important that you use a storage area that is not below this temperature.

Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites spontaneously.

Diesel particulate filters are intended to reduce soot emissions by as much as 80%. When the filter fails, the DPF (diesel particulate filter) light will come on. It indicates a partial blockage in the filter. ... In order to empty your DPF, you have to burn off the collected soot.

STP® Oil Treatment Diesel For extra engine protection STP® Oil Treatment for Diesel Engines is designed to fortify motor oil with an extra measure of additives, providing increased levels of detergent/dispersant, viscosity improver, anti-wear and anti-friction agents.

While most fuel additives are, at worst, harmless, Trotta warns against using engine cooling system additives that claim to plug leaks. These, she says, will only work temporarily on small leaks, will have no effect on larger leaks and could cause damage to your car's mechanics.

MB Enthusiast The BlueEfficiency and BlueTEC cars were available concurrently. The difference is that the BlueTEC ones have an AdBlu system which reduces NOx emissions, but increases CO2 emissions and increases fuel consumption. They are also down about 30bhp vs the 265bhp BlueEfficiency cars.

A diesel engine won't save you money on fuel if you're only taking short trips to the store, and it will end up costing you more than a gasoline engine in the long run. ... "A diesel does great in the city. It's not so much the stop-and-go driving that's the problem for this driver.

The most reliable way to test the diesel is to pull a sample and send it to a lab, there they can run it through a spectrophotometer and tell if there is any dye present (even though the diesel may appear normal to the eye).

Turbochargers provide additional horsepower to your petrol-powered engine. They do so by increasing the amount of air and fuel that enters each combustion chamber. Meanwhile, diesel fuel burns at a lower temperature. That causes it to create more exhaust gas, but diesel engines also have higher compression ratings.

The cleaner works by reducing the combustion temperature of the soot particles. ... Exhaust gases will flow much more quickly through a DPF which is emptier and not filled with soot particles. This will reduce fuel consumption and mean that you can travel further without having to fill up your tank.

If you put diesel into a petrol car, the potential damage isn't as severe but it will still cause your engine to smoke a bit and run badly, so it's best to get the diesel out as soon as possible. By not turning your engine on you can save yourself a lot of hassle and make the repair man's job a lot easier.

['Always pour AdBlue into the AdBlue tank. ... ', 'Only use AdBlue equipment when storing or refilling AdBlue.', 'Keep your AdBlue equipment clean and free from dust or dirt.', 'Ensure your AdBlue tank and container seals remain intact.', 'Use demineralised water (or AdBlue) when cleaning internally or priming AdBlue equipment.']

They use concentrated diesel fuel additives that might cost them three or four cents a gallon to use. When you balance the value of the benefits vs. the cost of the additive, the answer to the question is a resounding Yes. Diesel fuel additives are worth it for them.
