Emission standards and tightness tests

 

EU standards as a requirement for fuel and exhaust gas components

Rising ozone levels, smog, acid rain - modern life and technical progress take their toll on the world around us. Over a billion cars are registered worldwide, and together they blast endless amounts of exhaust into the atmosphere each day. This not only pollutes the environment but also has adverse effects on the people who live in it. Against this background, reducing emissions is one of the greatest challenges in the field of environmental protection. Statutory caps and regulations on emissions become increasingly important – the European Union is one of the forerunners in this area. Improving the quality of the air we breathe has long been one of the declared goals of the European Union and represents an important focus of its environmental policy. Since restrictions were put in place for the first time in 1970, the European Union has continued to lower the ceiling on car exhaust emissions. For car manufacturers, the environmental friendliness of their vehicles is thus understandably an important issue: With the aid of ever new technology, they work towards keeping emissions to a minimum. Euro 5 and euro 6 are standards that define emissions ceilings for motor vehicles. These standards also set the limits for automotive assemblies and components that carry liquids or gases.

Even before they are fitted inside a car, the fuel tanks or injection systems are required to be tested to ensure they comply with the leak rates stipulated by the standard. This procedure is supposed to minimize the environmental impact of motor vehicles. Each supplier must rigorously monitor and document the tightness of the assemblies. With its wide-ranging leak detection portfolio, Pfeiffer Vacuum has the right solution for leak testing every assembly and component in the automotive sector.
