Для высокого форсирования ДВС, имеющих величину среднего эффективного давления 2,5 МПа, необходимо обеспечить степень повышения давления πк = 4,5. Наиболее рационально для достижения такого πк применять двухступенчатый наддув с промежуточным охлаждением. Преимуществом такой системы является использование в обеих ступенях стандартных турбокомпрессоров. Совместно с двухступенчатым наддувом применяют цикл Миллера, который снижает температуру свежего заряда за счет раннего закрытия впускного клапана за 40…60 градусов поворота коленчатого вала до НМТ.</p></abstract><trans-abstract xml:lang="en"><p>At the present stage of internal combustion engine development, the application of supercharging allows to meet the requirements to the tractive characteristics of vehicles, to reduce or keep the weight and dimensions of the engine, to improve the economic performance, to reduce the emissions of carbon dioxide and toxic substances. For high boosting of internal combustion engines having the value of average effective pressure of 2.5 MPa, it is necessary to provide the degree of pressure increase πk = 4.5. The most rational way to achieve such πk is to use two-stage supercharging with intercooling. The advantage of such a system is the use of standard turbochargers in both stages. Together with two-stage supercharging the Miller cycle is used, which reduces the temperature of fresh charge due to early closing of the intake valve for 40...60 degrees of crankshaft rotation up to BDC.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экономические показатели</kwd><kwd>двухступенчатый наддув</kwd><kwd>цикл Миллера</kwd><kwd>топливоподача</kwd><kwd>электрогидравлическая форсунка</kwd><kwd>оксиды азота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>economic indicators</kwd><kwd>two-stage supercharging</kwd><kwd>Miller cycle</kwd><kwd>fuel supply</kwd><kwd>electrohydraulic injector</kwd><kwd>nitrogen oxides</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Experiments and Modeling on Spray Distributions in the Combustion Chamber of a Direct Injection Diesel Engine / Takuo Yoshizaki [et al.] // SAE Tech.
