Abstract
The paper is devoted to the perfection of mixture preparation in MPFI engines with the goal of improving economic and ecological parameters of modern vehicles. As is shown, the main problem in large cities is low average vehicle speed and engines running on partial modes, with one mixing not intensively enough, and the combustion processes proceeding slowly. To solve the indicated problems of partial modes applying swirl flows is justified. A description of a laboratory workbench for the simulation and research of the fuel evaporation process is submitted and some results of experiments are given. The description of a proposed inlet system for engines with variable vortex formation is presented. The results of motor tests of the new inlet system for a 1.5L MPFI 4-cylinder engine are given.
