Mandatory 25 years catalyst meets
Ran September 1984 when the German government of the time, dodging a veritable hailstorm of criticism, approved the compulsory catalyst for all new cars with gasoline engine. That decision marked the starting gun for concern for the environment is now widespread standard in the automotive world. Today, no one conceived that a vehicle leaves the assembly line unequipped some type of cleaning system exhaust.
Now we talk about global warming, with CO2 as an enemy to beat. Then, the buzzword was "acid rain" that burned forests, as were the toxic gases from exhaust pipes which posed the greatest threat. In the United States and Japan and catalysts they were used, but the German government brought its obligation to the country and, by extension, the whole of Europe.
The further ado came from neighboring countries (with Spain in the lead), due to the need to replace normal unleaded gasoline other, pain of seeing jeopardize the influx of German tourists on their impressive tourism vehicles. To calm down a five-year moratorium agreed. Finally, it was possible to remove the old leaded gasoline with additives, one of the worst forms of mass poisoning ever known to human society.
To lighten the replacement process, the German government approved certain tax breaks for cars catalysed. In Spain failed, as expected, that political will. And the possibility of the average Spaniard to gain a German secondhand car at a good price (yes, no catalyst) did the rest: our roads were invaded by a huge fleet of bemeuves, merches and Audis in their country of origin they had finished dismantling. All European tankers loaded with leaded gasoline headed to the Iberian Peninsula.
Fortunately, in these 25 years they have undertaken more regulations to reduce emissions of gases toxic cars with internal combustion engine. Besides the three-way catalyst for gasoline engines, the diesel oxidation catalysts equipped and particulate filters. 2014 will come the Euro-6 standard, which will help make even less messy to possibly be one of the last generations of traditional engines.
