В качестве объектов исследования рассмотрены двухцилиндровый (2Ч 7,6/7) и четырехцилиндровый (4Ч 7,6/7) двигатели со степенью сжатия ε = 9,9. Исследование проведено при условии поддержания коэффициента избытка воздуха α = 1 при обоих ДсИЗ как на бензине, так и на аммиаке. Результаты показывают, что применение КЭУ позволяет уменьшить рабочий объем двигателя и снизить расход топлива за ездовой цикл на 18%. Отмечено уменьшение количества теплоты, подводимого в цикл с топливом на режимах средних и высоких нагрузок при обеспечении суммарной заданной мощности КЭУ, необходимой для движения транспортного средства. Это нивелирует необходимость повышения запаса топлива на борту автомобиля при переходе с бензина на аммиак, однако возникает необходимость выбора рационального сочетания требуемой мощности ДсИЗ и электрического двигателя.</p></abstract><trans-abstract xml:lang="en"><p>The results of a computational study of the working process of a modern spark ignition engine when operating as part of a combined power plant (CPP) of a passenger car moving along the driving cycle are presented. Two-cylinder and four-cylinder engines with a compression ratio ε = 9.9 were considered as objects of research. The study was carried out under the condition that the excess air coefficient α = 1 was maintained for both spark ignition engines using both gasoline and ammonia. The results show that the use of CPP makes it possible to reduce engine displacement and reduce fuel consumption over the driving cycle by 18%. A decrease in the amount of heat supplied to the cycle with fuel at medium and high load modes was noted while ensuring the total specified power of the CPP required for vehicle movement. This eliminates the need to increase the fuel supply on board the vehicle when switching from gasoline to ammonia, but there is a need to select a rational combination of the required power of a spark ignition engine and an electric motor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>двигатель с искровым зажиганием</kwd><kwd>альтернативное топливо</kwd><kwd>аммиак</kwd><kwd>комбинированная энергетическая установка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spark ignition engine</kwd><kwd>alternative fuel</kwd><kwd>ammonia</kwd><kwd>Combination Power System</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">Альтернативные топлива для двигателей внутреннего сгорания / А.
