Chlorofluorocarbons are the best possible solvents to have in car engines for cleaning the electronic sensors in modern automobile ignition systems  These solvents have contributed significantly to automakers' ability to meet legally mandated emission standards
Now automakers will have to phase out the use of chlorofluorocarbons at the same time that emission standards are becoming more stringent
Car engines will be radically redesigned so as to do away with the need for cleaning the electronic ignition sensors.
