Kramar S. The improvement of fuel economic and lowering of toxicity of the two- stroke gasoline engine by separate supply of a fresh charge

The thesis is devoted to perfecting of working process of the two- stroke gasoline engine by separate supply of the fresh charge, allowing to supply increase of fuel profitability and lowering of toxicity of exhaust gases up to a level of four- cycle engines with spark ignition. The experimental of the two- stroke gasoline engine with separate supply of the fresh charge, ensuring purging of the cylinder by air, supply of a combustion- mixture af-ter gas exchange and organization of a stratification of a charge in the combustion chamber is created. Mathematical models and programs of calculation on computer of the working process of the two- stroke gasoline engine with separate supply of the fresh charge are developed. Settlement- experimental researches of the two- stroke gasoline engine with separate supply of the fresh charge as a result of which it is established are carried out, that the two- stroke engine may make a real competition to modern four- cycle engines with spark ignition.
