PROCEDURE FOR FEEDING A FUEL-AIR MIXTURE TO A COMBUSTION ENGINE AND DEVICE FOR PUTTING INTO PRACTICE OF THE PROCEDURE.

摘要

Procedure for feeding a fuel-air mixture (() to a combustion engine, in which a primary fuel-air mixture is prepared from a primary air stream and a fuel and this fuel-air mixture is impoverished primary by means of a secondary air stream sucked into a double-acting air funnel (2) before the fuel-air mixture (() passes through the opening of the butterfly valve of the combustion engine, characterized in that it is prepared a mixture of primary fuel-air with a mixing ratio (1 from the primary air stream and the fuel and then, downstream of the mixing site, at the beginning of the expansion segment (2c), secondary air is aspirated towards the funnel through air intake openings (8) at the same height as the funnel neck or just after the funnel neck (2b), and said secondary air is combined with the fuel-air mixture primary and eventually with more primary air and thus a mixture of fuel-air (() with a mixing ratio ( 1.
