Korogodsky V. The mixing and combustion processes perfection in an engines with spark ignition and direct fuel injection

The thesis is devoted to development of effective working process in engines with internal mixing and spark ignition air-fuel mixture. Offered supply fuel systems ensure volumetric, volumetric - film and film mixing in engines with half-divided combustion chamber and stratification of air-fuel mixture. The calculation model volumetric - film mixing, submitted by author, allow to estimate vaporization time of fuel drops for each site in processes mixing. Theoretical dates are confirmed on the results of experimental researches. The offered way of film mixing in an one-cylinder two stroke engine with direct injection of fuel in the combustion chamber ensure using gasoline, diesel fuel and their mixtures, decreasing of fuel consumption on 40-45% and harmful substances in exhausted gases on 70-90% in compariation with the carburetor supply fuel system engines. An engine building.
