ДВУХТАКТНЫЙ ДВС СО ВСПОМОГАТЕЛЬНЫМ ЦИЛИНДРОМ (ВАРИАНТЫ)

Номер: RU2621423C2

Группа изобретений относится к двигателестроению, а именно к двухтактным двигателям внутреннего сгорания (ДВС). Техническим результатом является снижение расхода масла, увеличение наполнения цилиндра. Сущность изобретений заключается в том, что в первом варианте вспомогательный цилиндр выполнен соосно рабочему на общем штоке. Поршень вспомогательного цилиндра образует с одной стороны камеру всасывания, а с противоположной стороны – камеру предварительного сжатия. Свободный конец штока поршней снабжен скользящим упором и связан с кривошипно-шатунным механизмом. Камеры цилиндров соединены друг с другом воздуховодами, где по ходу газов установлены обратные клапаны, причем камера всасывания соединена еще и воздуховодом с атмосферой, в котором также по ходу газов установлен обратный клапан и форсунка подачи масла в воздушный поток. На выпускной магистрали установлено дроссельное отверстие с подвижным элементом. Во втором варианте выполнения двигателя рабочий и вспомогательный цилиндры расположены параллельно друг другу, а штоки их цилиндров взаимодействуют между собой посредством коромысла, ось качания которого закреплена на корпусе ДВС с возможностью перемещения между продольными осями цилиндров. В результате при неизменной величине хода поршня рабочего цилиндра можно изменить величину хода поршня вспомогательного цилиндра, изменяя таким образом степень сжатия в камере предварительного сжатия. 2 н. и 2 з.п. ф-лы, 2 ил.

FIELD: engines and pumps. SUBSTANCE: invention relates to two-stroke internal combustion engines with a split cycle. Principle of the invention consists in that the engine has a single or multi-stage pre-cooled compression, which allows the temperature and pressure of the air sucked into the combustion cylinders to be under full control, and due to that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the autoignition threshold. Since this design can effectively regulate and set the maximum pre-ignition temperature of the air-fuel mixture, it can work on virtually any type of liquid hydrocarbon fuel without knocking. Due to its higher compression ratio, this "push-pull" motor generates energy equal to or greater than the four-stroke CWPSC engine in a lighter and smaller casing and with equal or greater efficiency.

Four-Cycle Internal Combustion Engine with Pre-Stage Cooled Compression

Номер: US20150252718A1
Автор: Filip KRISTANI
Принадлежит: Individual

A four-cycle internal combustion engine has a single or multi-stage pre-cooled compression, which allows the temperature and pressure of intake air to the combustion cylinders to be tightly controlled, so that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the air/fuel mixture auto-ignition threshold. The minimal threshold pressure of air intake is determined to be >1.8 Bars at sea level and a minimal temperature drop of at least 50° C. at the heat exchanger air cooling radiator. Because this design can effectively regulate and set the maximum pre-ignition temperature of the fuel-air mixture, it can combust virtually any type of liquid hydrocarbon fuel without knocking This four-cycle engine, due to its higher compression ratio, generates power equivalent to or greater than a standard four-cycle engine in a smaller and lighter engine and at a higher efficiency.

Номер: US4333424A
Автор: Richard McFee
Принадлежит: Individual

The engine has a compressor which compresses air for delivery via a heat exchanger to an expander. The expander receives the compressed air and fuel and, while combustion occurs during a power stroke, the air pressure is reduced to atmosphere and the expander drives a crankshaft. The fuel is injected at a rate to maintain the air temperature at the entry temperature. The exhaust passes through the heat exchanger to heat the incoming flow of compressed air to the expander. Energy may be stored via the crankshaft or used directly.

Internal combustion engine

Номер: RU2617519C1

FIELD: engines and pumps. SUBSTANCE: air is sucked through the intake valve 17 into one part of the cavity between the piston 8 and the cylinder cover 10, and in the right part of the cylinder 11 cavity the air is compressed by the piston 9. When the piston reaches the 0.96 stroke mark, the window 16 will start to open, the combustion products from the left side of the cylinder 11 will flow into the atmosphere, the pressure in this part of the cavity will lower and the air compressed by the piston 8 along the duct 13 through the intake valve 14 will rush to the left side of the cylinder 11, carrying out its purging. The injector injects fuel, which ignites and starts to burn, and the resulting combustion products press against the piston 9. When the shaft 3 passes the corner 110° the piston 9 will again be at the 0.96 stroke mark, moving already in the opposite direction, and the piston 8 will be at 0.61 mark and will continue to move in the same direction. And window 16 will begin to close completely, and blowdown will be finishing. The air will then flow into the left part of the cylinder 11 via the channel 13 through the inlet valve 14, increasing the amount of air in the latter. As the piston 8 reaches the dead point, air injection into the right part of the cylinder 11 cavity will end, at that, its piston will be at ~the 0.4 stroke mark and will continue to move, compressing the air in front of him. Once the piston 9 is near 0.03, the window 16 will begin to open slightly, releasing the combustion products from the right side of the cylinder 11 cavity, the pressure in it will drop and the air compressed by the piston 8 will rush through the inlet valve 15 performing a purge. At the same time, a fuel injected by the left nozzle will ignite and begin to burn. Then the described cycle will be repeated. EFFECT: simplification of design, expansion of functionality and improvement of performance characteristics. 3 cl, 10 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 ...

Номер: RU2744262C1

FIELD: engine building.SUBSTANCE: invention can be used in production of gasoline engines and diesel engines. Essence of invention consists in fact that during movement of pistons 3 of cylinders 1, 2 downwards in cylinder 1 expansion of combustion products takes place, and cylinder 2 piston suction through oxidant through channel 6 with open inlet valve 9. When pistons reach lower dead center valve 9 closes, and outlet valve 7 opens, allowing combustion products to exit cylinder 1 through channel 4. As a result, pistons movement upwards is accompanied by combustion products output from cylinder 1 and oxidizer compression in cylinder 2. At piston stroke of cylinder 1 to point corresponding to moment of ignition, bypass valve 8 is opened, as a result, compressed oxidant through channel 5 enters combustion chamber 10, wherein blowing of latter and removal of combustion products residues from it. After that, valve 7 is closed, compressed oxidizer continues to flow into combustion chamber, filling it. Pressure above pistons 3 is equalized, and valve 8 is closed. Further, liquid component is supplied under high pressure by injection device 11 and is technically ignited. Combustible mixture is burnt, the working stroke begins, during which pistons 3 move synchronously downwards. In the same way, the engine is operated in diesel mode.EFFECT: technical result is higher efficiency of engine, reliability, operational and functional characteristics of engine, as well as simplification of its design.5 cl, 5 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 744 262 C1 (51) МПК F02B 33/22 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F02B 33/22 (2020.02) (21)(22) Заявка: 2019138108, 25.11.2019 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): Оленев Евгений Александрович (RU) Дата регистрации: 04.03.2021 Приоритет(ы): (22) Дата подачи заявки: 25.11.2019 (45) Опубликовано: 04.03.2021 Бюл. № 7 2 7 4 4 ...

SUBSTANCE: internal combustion engine operation method consists in supply of charge to combustion chambers of the main and additional cylinders with various diameters, which are connected to each other and in which pistons are arranged, and in compression of charge with pistons in both cylinders. Piston of additional cylinder is delayed as per rotation phase of shaft from piston of the main cylinder of up to 120 degrees, and when piston of the main cylinder reaches its upper dead point when larger portion of charge is in additional cylinder, charge is boosted with piston of additional cylinder. Mixture is pressed by piston of the main cylinder, but it is not brought to self-ignition, thus it is prepared for further quick ignition; and compressed homogenised fuel-air mixture is boosted with piston of additional cylinder, and its temperature and pressure in combustion chamber is brought to compression self-ignition of mixture. EFFECT: simpler design, possibility of control and regulation of self-ignition moment of homogenised fuel-air mixture, lower specific fuel flow and higher ecologic characteristics of the engine. 13 cl, 15 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 422 651 (13) C1 (51) МПК F02B 9/02 (2006.01) F02B 75/28 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2010115063/06, 15.04.2010 (24) Дата начала отсчета срока действия патента: 15.04.2010 (73) Патентообладатель(и): Габдуллин Ривенер Мусавирович (RU) R U Приоритет(ы): (22) Дата подачи заявки: 15.04.2010 (72) Автор(ы): Габдуллин Ривенер Мусавирович (RU) (45) Опубликовано: 27.06.2011 Бюл. № 18 2 4 2 2 6 5 1 (56) Список документов, цитированных в отчете о поиске: SU 1229397 А1, 07.05.1986.

IC engine with tandem cylinder arrangement

Номер: DE4418286A1
Автор: Karl-Heinz Beiring
Принадлежит: BEIRING KARL HEINZ

The IC engine has a series of combustion chamber working cylinders (12) in each of which a reciprocating piston (11,21,31,41) moves. Above it are gas inlet shafts (15.2.1 and 15.2.2) which allow regulated induction according to piston travel. Each piston is connected to a crankshaft (5) which also connects via a con rod (38) to a tandem auxiliary piston/cylinder fitted in tandem. This piston has a cylinder head with heat exchangers (36,37). The piston motion helps induction as it moves up and as the exhaust gas heats the exchangers the piston is driven down expelling exhaust gases from the transfer passage (17) through the work cylinder and out the exhaust port (62).

Double acting internal combustion engine with regeneration of heat

Номер: RU2663369C1

FIELD: machine building.SUBSTANCE: invention relates to machine building, in particular to engine building. Essence of the invention lies in the fact that in an internal combustion engine consisting of block of cylinders, pistons, rod, connecting rod, crankshaft crankcase, system for preparing and feeding a fuel mixture, suction and exhaust valves, start-up systems, cooling systems and lubrication systems, and the pistons are double-acting. In the upper part of the pistons, processes of the working stroke and exhaust of end gases are performed, and in their lower part, suction and compression of air are performed. According to the invention, the air is preheated in the regenerator from the heat of the end gases before being fed into the engine cylinders. And the air, compressed in the lower part of one of the cylinders, is passed through the regenerator to the top of the other cylinder, and the end gases from each cylinder are fed to the regenerator. Also, for additional heating, the gas is reversed by withdrawing part of the end gases from the cylinder during expansion and feeding them through the reverse valve to the regenerator.1 cl, 2 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 663 369 C1 (51) МПК F02B 33/12 (2006.01) F02B 33/22 (2006.01) F02G 5/02 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F02B 33/12 (2018.02); F02B 33/22 (2018.02); F02G 5/02 (2018.02) (21)(22) Заявка: 2016129847, 20.07.2016 (24) Дата начала отсчета срока действия патента: Дата регистрации: 03.08.2018 (45) Опубликовано: 03.08.2018 Бюл. № 22 Адрес для переписки: 443100, г.
