 A version with a single-barrel carburetor was installed in some early Renault Trafic models and some R21, called the F1N.The petrol version was also built with multi-point fuel injection as the F3N.This was fitted to the U.S. versions of the Renault 9 and Renault 11 (Renault Alliance and Encore), as well as to GTE models of the Renault 5 and 11 sold in some countries such as Switzerland and Germany - as the old carburetted turbo Cléon-Fonte engines no longer met the pollution standards in these countries.
