Main statesments are described as well as new elements of -a mathematical model of a precise method of the hydrodynamic calculation of the fuel delivery process in automotive diesel engines. New statesments are different from ones developed earlier, in the offered technique a non-stationary nature of the flow is considered along all the hydrodynamic cycle, as well as the energy loss at the variation of shape and the hydrodynamic cycle channel size. Experimental and calculation data are compared, proving their good convergence.

Анализируется характер движения газа в коллекторе для двух способов присоединения выпускных диффузоров, обеспечивающих радиальный к стенке коллектора подвод газов, когда патрубки расположены посередине его высоты, либо тангенциальный подвод при опущенных патрубках. Приводятся зависимости расхода газа от угла поворота коленчатого вала для продувочных окон и выпускного клапана, а также поля проекций скоростей в характерных сечениях коллектора. Сопоставляются условия, влияющие на процессы очистки — наполнения цилиндров, для схем с радиальным и тангенциальным подводом более перспективным с точки зрения повышения топливной экономичности дизеля.

Рассматриваются современные тенденции борьбы с токсичностью автомобильных двигателей, дается оценка по степени вредности продуктов неполного горения в ДВС и описываются внедряемые мероприятия по экологии. Указываются направления создания рабочего цикла ДВС с нейтральным выхлопом, базирующегося на осушении горючей смеси и впускного коллектора (испарении бензина), сжигании бедных смесей методом расслоения заряда и электронного управления топливоподачей. Такое сочетание позволяет осуществить процесс в ДВС до конечных продуктов СО2 и Н20 без нейтрализаторов.
