New Emissions Rules Drive Exhausts Technology
Automotive exhaust systems used to be straightforward. However, what was once a relatively straightforward product is becoming increasingly complex according to research undertaken by industry website just-auto.
Bromsgrove, UK (PRWEB) March 28, 2008 -- Automotive exhaust systems used to be straightforward. However, what was once a relatively straightforward product is becoming increasingly complex according to research undertaken by industry website just-auto.
The exhaust system has three main functions--two environmental and one performance-related. The first function is to minimise carbon monoxide, unburnt hydrocarbons and oxides of nitrogen, and direct them out of the engine and away from the passenger compartment.
The second is to minimise noise created by the car's engine.
The third is to help optimise engine performance by providing a continuous, smooth flow of gas out of the engine. The exhaust can also be 'tuned' to produce a distinctive and characteristic note, such as that of a Porsche or Alfa Romeo.
Technical developments in the hot end of the exhaust are highly influenced by the new emissions legislations. Consequently, we are seeing the emergence of new exhaust system technologies for both gasoline and diesel engines, just-auto says.
As each new emissions regulation swings into force, more content is added to the exhaust in order to comply.
This adds value to the overall price of the system. Manufacturers believe that with increasingly strict emissions regulations forecasted, the emissions control content per light vehicle will rise over the next few years as a result of the introduction of multiple catalytic converters per vehicle, heat exchangers and particulate filters.
The emission standards are, however, technology-neutral.
That means automakers are free to use whatever technology they choose in order to meet the standards.
