How do fuel ethers contribute to addressing car pollution ?
Through their contribution to more complete fuel combustion and the dilution of less desirable components fuel ethers make a significant contribution to reducing car pollution. The environmental benefits of fuel ethers can be divided into two main categories. There are so-called “direct” effects, mainly due to more complete fuel combustion (as a result of organic oxygen presence) and “indirect” ones, coming from the dilution of other, less desirable, gasoline pool components. It is also important to note that their use reduces emissions from all types of gasoline vehicles, regardless of their emission-control technology. Although it seems to be of less importance for EURO IV standard cars with the newest catalyst technology, fuel ethers help to improve combustion for these cars especially in the cold starting phase of the engine, when the catalytic converter is not working. Direct effects include the reduction of both “regulated” and “unregulated” emissions. Among the specific pollutan
