reducing fuel consumption

Brian Madden, SEO Strategist for Crown Oil Co. dropped in to offer some information on a new technology that helps vehicles reduce the amount of pollutants in the environment.

 -- Reducing Fuel Consumption -- 

 If you drive a Heavy Goods Vehicle (a.k.a. HGV – primarily used in the haulage industry) there is a good chance that you have heard of, or need to use AdBlue. It became widespread in 2006 when a law was passed requiring vehicle manufacturers to reduce the amount of pollutants in the environment. AdBlue is used in a process called SCR (Selective Catalytic Reduction), which reduces the amount of toxins released from burning fuel.

AdBlue is the term used globally for an additive established for the biochemical and motoring divisions. It’s an exceedingly high cleanliness, 32.5% aqueous solution of urea (minimum 31.8% - maximum 33.3%) that converts nitrogen oxides into nitrogen (N2) and aquatic vapor (H2O) by means of biochemical reduction.

Content of numerous metals must not surpass 0.2 mg/kg for each of them in order not to infect the catalytic converter. This means AdBlue cannot be replaced by urea in farming. The structure and quality standards are controlled by DIN 70070.

AdBlue is an unscented, colorless artificial product: it is not considered a hazardous substance inasmuch as it’s neither combustible nor poisonous. 

SCR technology has remained in use since the early ‘80s in thermal and fossil fuel power stations, on gas turbines, train diesel engines and big marine authority units. In all these applications burning is enhanced with the double aim of attaining improved performance and straight reduction of particulate releases.

Post-treatment is founded on a modest principle: the biochemical reaction of ammonia (NH3) with the nitrogen oxides NO and NO2 to create two mild substances – aquatic vapor (H2O) and nitrogen (N2). 

These are the applicable formulas:

 NO + NO2 + 2 NH3 N2 + 3 H2O

Then for whichever residual oxygen current in exhaust vapors

4 NO + O2 + 4 NH3 4 N2 + 6 H2O

6 NO2 + 8 NH3 7 N2 + 12 H2O

In very big systems ammonia is drained directly from forced tanks. With respects to highway vehicles, the usage of clean ammonia has remained studied however in the end was abandoned because of difficulties of keeping it on board automobiles and in refilling stations. The standardized urea method in the form of a solution – AdBlue – was desirable for two reasons: this produce is not branded as a hazardous substance, there is no risk in the event of spills and it’s easy to hoard both on board automobiles and at hauler premises, in spite of the drawback that it gels at temperatures below -11°C.
