What the inquisitive mind of a Russian motorist does not think about in an indestructible desire to save money on car maintenance. The AvtoVzglyad portal discovered a way
Anyone who more or less follows the technologies for reducing the amount of harmful emissions from internal combustion engines, as well as motorists who have had to drive diesel cars of the EURO-5 class, most likely know very well what AdBlue or “urea” is, and “with which they eat it.” For all others, we remind that AdBlue is a trademark under which a special urea solution is sold in Europe – urea H2N-CO-NH2. This substance in the liquid contains 32.5%, and the remaining 67.5% is distilled water.
AdBlue is used in selective catalytic converter (SCR) diesel vehicles. The injection of this solution into the exhaust duct of a modern heavy fuel engine takes place before the catalytic converter. Under the influence of the high temperature of the exhaust gases, ammonia is released from the urea. Furthermore, it interacts with nitric oxide in the gases that come out of the cylinders. The result of a chemical reaction is absolutely harmless to nature and humans water vapor and nitrogen.
But we are not interested in this aspect, but in the “folk art” of car owners who use AdBlue or its much cheaper counterparts sold at Russian gas stations. Note that car owners use urea to improve their technical well-being and also gasoline cars.
Namely – for cleaning the catalytic converter. As you know, in quite old cars it can eventually become clogged with fuel combustion products. They impede the exhaust of exhaust gases from the engine and thereby steal its power. Usually such a “disease” is eliminated in a radical way: a catalytic converter is cut out, a steel pipe is welded into place, and the “brain” of the car is reprogrammed so that it does not swear at the consequences of such an amputation.
But such a result can be avoided – with the help of urea. To do this, you must unscrew the oxygen sensor (lambda probe) in front of the catalytic converter. Through the opened hole we inject about 20 milliliters of diesel urea or AdBlue into the exhaust with a syringe – which is available. Then insert the lambda probe and start the engine. As the engine warms up, light smoke begins to flow from the exhaust pipe. This is evidence that the catalyst cleaning process is proceeding as expected.
When it stops, you can assume that the procedure has been completed and evaluate the results. On the road, you will definitely feel that the power has returned to your car’s engine – since the “plugs” in the catalytic converter have disappeared and the engine has been able to “breathe” completely.
