Abstract

FIELD: mechanical engineering. SUBSTANCE: method includes injection of fuel in working and expanding cylinders, discharging of exhaust from cylinders and ejecting of gases delivered from the working cylinder. By-passing of gases from the working cylinder is shut-off when discharging of exhaust gases begins. The internal combustion engine has working and expanding cylinders, inlet and outlet passages interconnected through by-pass passage provided with a gate kinematically connected to a crankshaft. EFFECT: enhanced efficiency. 3 cl, 1 dwg

Description

Изобретение относится к области машиностроения. The invention relates to the field of engineering.

Известен двигатель внутреннего сгорания, содержащий основной и расширительный цилиндры сообщенные между собой каналом, форсунку подачи пара в основном цилиндре и эжектор в выпускном канале последнего. A known internal combustion engine containing the main and expansion cylinders communicated with each other by a channel, a steam nozzle in the main cylinder and an ejector in the exhaust channel of the latter.

Эффективность отсоса в известном объекте понижена вследствие частичного подсоса в зону эжектирования из расширительного цилиндра через перепускной канал. The suction efficiency in the known object is reduced due to partial suction in the ejection zone from the expansion cylinder through the bypass channel.

Цель изобретения - повышение эффективности двигателей путем повышения уровня отсоса. The purpose of the invention is to increase the efficiency of engines by increasing the level of suction.

Поставленная цель достигается путем разобщения между собой цилиндра по меньшей мере при выпуске. This goal is achieved by separating the cylinder from each other, at least during release.

На чертеже изображен предлагаемый двигатель. The drawing shows the proposed engine.

Двигатель содержит основной цилиндр 1, сообщенный с расширительным цилиндром 2 перепускным каналом 3, впускные 4 и 5 каналы и выпускные 6 и 7 каналы цилиндров, эжектор 8 в канале 6 и паровую форсунку 9 в рабочем цилиндре 1. Двигатель содержит дополнительно в перепускном канале 3 заслонку 10, кинематически связанную с валом 11 двигателя. The engine comprises a main cylinder 1, in communication with the expansion cylinder 2 bypass channel 3, inlet channels 4 and 5 and exhaust channels 6 and 7, an ejector 8 in channel 6 and a steam nozzle 9 in the working cylinder 1. The engine further comprises a shutter in the bypass channel 3 10 kinematically coupled to the motor shaft 11.

Двигатель работает следующим образом. Через каналы 4 и 5 в цилиндры 1 и 2 поступает свежий заряд, который сжимается и воспламеняется. Через форсунку 9 в цилиндр 1 подается пар, который вытесняет газы из цилиндра 1 через канал 3 в цилиндр2, газы в цилиндрах расширяются и выпускаются через каналы 6 и 7. Одновременно с началом выпуска канал 3 перекрывается заслонкой 10, работающей от вала 11. Разобщение цилиндров предотвращает попадание газов из цилиндра 2 к эжектору 8, что обеспечивает его более эффективную работу. The engine operates as follows. Through channels 4 and 5, fresh charge enters the cylinders 1 and 2, which is compressed and ignited. Through nozzle 9, steam is supplied to cylinder 1, which displaces gases from cylinder 1 through channel 3 to cylinder 2, gases in the cylinders expand and exhaust through channels 6 and 7. Simultaneously with the start of production, channel 3 is blocked by a valve 10 operating from shaft 11. Separation of cylinders prevents the ingress of gases from the cylinder 2 to the ejector 8, which ensures its more efficient operation.
