The first prototypes were built almost in parallel with the first automobiles and laid foundations of how a catalytic converter should work by using platinum, iridium, and palladium in a tubular cylinder housing to filter the fumes. It was clear that some form of an exhaust filter was necessary to reduce the number of emissions leaving the exhaust system. Swapping to direct-injection systems allowed for more precise administration of fuel, greater performance, and lower emissions output, but that was still not enough to satisfy the environmental standards. On top of that, through ineffective government regulation, leaded gasoline remained in use until 1996, even though unleaded gas was readily available since 1975.Ĭombine all of these factors together, and you get toxic levels of congestion in cities and a serious global environmental hazard. To make matters worse, most vehicles at that time used carburetor injection which is far from an optimal system.
