Next-generation GDI

Will new efficiency and emission rules mean major changes for gasoline direct-injection technology?

It has been rightly said, “a man refuses to move unless kicked in his hind.”

Take for example the steep decline in the usage of carbureted engines during the '90s. The catalytic converter was mandated in new petrol-powered vehicles, which was incompatible with unregulated fuel-air mixture combustion, characteristic of carbureted injection. This eventually led to the discontinuation of carburetors and today every petrol engine employs the multi-point fuel injection (MPFi) system. Evidently, it was the new emissions regulations two decades back that was the “kick to the hind,” rather than inherent inefficiencies of the traditional system as is popularly believed. We expect to see a similar trend today and in the future thanks to the stricter-than-ever emissions and efficiency legislations.
