Description

Изобретение относится к двигателестроению и применимо для нагрева (охлаждения) и привода жидкостных систем. The invention relates to engine building and is applicable for heating (cooling) and driving fluid systems.

В "Тепловом балансе ДВС" (см. книгу Алексеев и др. стр. 42-43) до 45% отработанного тепла выбрасывается в атмосферу. In the “Thermal balance of internal combustion engines” (see the book by Alekseev et al. P. 42-43), up to 45% of the waste heat is emitted into the atmosphere.

Известен способ предпускового нагрева жидкостных систем двигателя, осуществляемый факельным нагревом секций подогревателя (см. описание изобретения по патенту РФ 2068114, кл. F 02 N 17/04 на "Предпусковой подогреватель ДВС"). Недостатком является отсутствие циркуляционного привода. There is a method of prestarting heating of liquid engine systems, carried out by flare heating of the heater sections (see the description of the invention according to the patent of the Russian Federation 2068114, CL F 02 N 17/04 on the "engine pre-heater"). The disadvantage is the lack of a circulation drive.

Циркуляция жидкостных систем в ДВС осуществляется механическими насосами (см. книгу В.П.Алексеева и др. "Двигатели внутреннего сгорания", изд. Машгиз, М., 1960 г. стр. 100, 103, 193, на фиг. 56, 57 и 118). The circulation of liquid systems in the internal combustion engine is carried out by mechanical pumps (see the book by V.P. Alekseev and others. "Internal combustion engines", published by Mashgiz, M., 1960, pages 100, 103, 193, in Fig. 56, 57 and 118).

К недостаткам относятся:
- каждое приводное насосное устройство отнимает от двигателя полезную мощность;
- расходные баки автономны и не обеспечивают теплоаккумулирование.The disadvantages include:
- each drive pumping device takes useful power from the engine;
- consumable tanks are autonomous and do not provide heat storage.

Известно тепловое воздействие воздушной среды на жидкую среду через эластичную стенку (см. описание изобретения по а.с. 1488546 по кл. 4 F 04 B 19/24 на "Объемный насос с тепловым приводом"). The thermal effect of the air on the liquid medium through an elastic wall is known (see the description of the invention by AS 1488546, class 4 F 04 B 19/24 on “Volumetric pump with a heat drive”).

Подобное устройство не приемлемо для жидкостных систем ДВС как конструктивно, так и по КПД. Such a device is not acceptable for liquid ICE systems both structurally and in terms of efficiency.

Технической задачей предлагаемого изобретения является упрощение способа нагрева и привода жидкостных систем двигателя и создание устройств для их осуществления. The technical task of the invention is to simplify the method of heating and driving liquid engine systems and creating devices for their implementation.

Технический результат достигается за счет того, что первоначальным источником нагрева и энергии является топливный парогазообразователь, размещенный в выхлопном тракте коллектора, который и нагревает замкнутую полость с теплоносителем и перепускными клапанами создает импульсные выбросы. The technical result is achieved due to the fact that the initial source of heating and energy is a fuel gas generator located in the exhaust tract of the collector, which heats the closed cavity with the coolant and bypass valves creates pulsed emissions.

Привод жидкостных систем двигателя выполняется в следующей технологической последовательности. The drive of liquid engine systems is performed in the following process sequence.

После первоначального разогрева автономным подогревателем и запуска двигателя нагрев теплоносителя осуществляется от выхлопных газов. Импульсные выбросы из замкнутой полости коллектора по трубопроводам воздействуют на эластичные емкости расходных баков, которые, в свою очередь, воздействуют на их содержимое для смазки и питания ДВС. Сущность предлагаемого изобретения поясняется чертежами, где на фиг. 1 изображен выхлопной коллектор с замкнутой полостью; на фиг. 2 - принципиальная схема привода жидкостных систем. After the initial heating by an autonomous heater and engine start, the heat carrier is heated from the exhaust gases. Pulsed emissions from the closed cavity of the collector through pipelines affect the elastic containers of the supply tanks, which, in turn, act on their contents to lubricate and power the internal combustion engine. The essence of the invention is illustrated by drawings, where in FIG. 1 shows an exhaust manifold with a closed cavity; in FIG. 2 is a schematic diagram of a fluid system drive.

Выхлопной коллектор 1 состоит из замкнутой полости 2 с теплоносителем 3, выхлопного тракта 4 с парогазообразователем 5, который питается от топливной капельницы 6 и связан с электрозапальником 7, а воздух подводится через окно 8 с шибером 9. Принципиальная схема привода жидкостных систем представлена двигателем внутреннего сгорания 10, на котором установлен выхлопной коллектор 1 с замкнутой полостью 2, которая при помощи циркуляционных патрубков 11 с обратными клапанами 12 и 13 связана с питательными трубопроводами 14 и 15 жидкостной системы. Расходные баки 16 и 17 снабжены эластичными емкостями 18 и 19, горловины которых снабжены перепускными клапанами 21 и 22. Для обогрева салона автомобиля в систему привода включены емкостные нагревательные приборы 23. The exhaust manifold 1 consists of a closed cavity 2 with a coolant 3, an exhaust tract 4 with a steam generator 5, which is powered by a fuel dropper 6 and connected to an electric igniter 7, and air is supplied through a window 8 with a gate 9. The circuit diagram of the drive of liquid systems is represented by an internal combustion engine 10, on which an exhaust manifold 1 with a closed cavity 2 is installed, which is connected to the supply pipelines 14 and 15 of the liquid system using circulation pipes 11 with check valves 12 and 13. Consumable tanks 16 and 17 are equipped with elastic containers 18 and 19, the necks of which are equipped with bypass valves 21 and 22. To heat the vehicle interior, capacitive heating devices 23 are included in the drive system.

Нагрев и привод происходят следующим образом. Открывается электромагнитный клапан 24 топливной капельницы 6, топливо в парогазообразователе 5 подогревается и зажигается электрозапальником 7 при открытом воздушном окне 8. После прогрева и запуска двигателя нагрев теплоносителя осуществляется выхлопными газами. Обратные клапаны 12 и 13 позволяют осуществлять нагрев и импульсный выброс теплоносителя, давление которого по циркуляционным патрубкам и питательным трубопроводам передается эластичным емкостям 18 и 19 таким образом, что содержащиеся в них топливо и масло поступают к потребителю. Нагрев и циркуляция масла в поддоне двигателя предусматривает дополнительную вогнутую стенку 25 с пластинчатым клапаном 26 и отводящую подачу с "обраткой" 28. Heating and drive are as follows. The electromagnetic valve 24 of the fuel dropper 6 opens, the fuel in the steam-gas generator 5 is heated and ignited by the electric igniter 7 with the air window open 8. After warming up and starting the engine, the heat carrier is heated by exhaust gases. The non-return valves 12 and 13 allow heating and pulsed discharge of the coolant, the pressure of which is transferred to the elastic tanks 18 and 19 through the circulation pipes and feed pipes so that the fuel and oil contained in them are supplied to the consumer. Heating and oil circulation in the engine sump provides for an additional concave wall 25 with a plate valve 26 and a discharge feed with a "return" 28.

Работа циркуляции "мокрого" поддона также основана на импульсных подачах расширения и разрежения. The wet pan circulation is also based on pulsed expansion and expansion feeds.

В тропических условиях, когда вода и масло "кипят" теплоносителем может быть хладагент, на основе которого создается абсорбционный холодильник (не показан). In tropical conditions, when water and oil "boil" the coolant may be the refrigerant, on the basis of which an absorption refrigerator (not shown) is created.
