Abstract
Description
Изобретение относится к двигателе строению, в частности к устройствам для управления воздушной заслонкой карбюратора двигателя внутреннего сгорания. 5The invention relates to an engine structure, in particular to devices for controlling the air damper of a carburetor of an internal combustion engine. 5
Известны устройства для управления воздушной заслонкой карбюратора, содержащие исполнительный терморегулирующий орган для перемещения заслонки и электронагреватель, 10 включенный в цепь источника тока через термовыключатель (1].Known devices for controlling the air damper of a carburetor, comprising an executive thermostatic control for moving the damper and an electric heater 10 included in the current source circuit through a thermal switch (1].
Подобные устройства имеют тен- . денцию оставлять воздушную заслонку ^5 в ее исходном положении, т.е.Similar devices have a ten. leave the choke ^ 5 in its original position, i.e.
почти полностью закрытой, в течение слишком длительного периода времени после начала работы двигателя.almost completely closed for too long after starting the engine.
В результате топливо-воздушная 20 смесь, подаваемая в цилиндры двигателя, становится неоправданно богатой. Кроме того, подобное устройство требует‘-много времени для полного открытия закона при повышенной 25 температуре окружающей среды, так что и в этом случае богатая топливовоздушная смесь подаётся в цилиндры двигателя дольше, чем это необходимо. Это приводит к повышенному загряз- 30 нению окружающей среды выхлопными газами двигателя.As a result, the fuel-air 20 mixture supplied to the engine cylinders becomes unreasonably rich. In addition, such a device requires ‘-a lot of time for the law to fully open at an increased ambient temperature 25, so that in this case too, a rich air-fuel mixture is fed into the engine cylinders longer than necessary. This leads to increased environmental pollution by the exhaust gases of the engine.
Цель изобретения - повышение быстродействия устройства в широком диапазоне температур окружающей среды.The purpose of the invention is to increase the speed of the device in a wide range of ambient temperatures.
Цель достигается тем, что термовыключатель дополнительно связай по теплопередаче со вторым электронагревателем.The goal is achieved in that the thermal switch is additionally connected by heat transfer with a second electric heater.
На фиг. 1 показано устройство для управления воздушной заслонкой карбюратора, вертикальный разрез; на фиг. 2 - схема его работы.In FIG. 1 shows a device for controlling a carburetor air damper, vertical section; in FIG. 2 is a diagram of its operation.
Внутри корпуса 1 устройства установлен исполнительный терморегулирующий орган 2, представляющий собой термостатную металлическую спираль. В корпусе выполнены две выемки 3 и 4, в которых расположены два электронагревателя 5 и 6, выполненные из металла с положительным коэффициентом сопротивления и соединены между собой параллельно. В цепь 7 электронагревателя 6 включен термовыключатель 8. Терморегулирующий орган 2 связан по теплопередаче с электронагревателемг 5 и 6 при помощи элемента 9 теплоотвода, который в свою очередь соединен с корпусом 1. Устройство включается в работу посредством включателя 10, который подсоединяет его к аккумуляторной батареи 11.Inside the housing 1 of the device is installed thermostatic control element 2, which is a thermostatic metal spiral. Two recesses 3 and 4 are made in the housing, in which two electric heaters 5 and 6 are located, made of metal with a positive coefficient of resistance and interconnected in parallel. A thermal switch 8 is included in the circuit 7 of the electric heater 6. The temperature control element 2 is connected via heat transfer to the electric heater g 5 and 6 using the heat sink element 9, which in turn is connected to the housing 1. The device is turned on by means of a switch 10 that connects it to the battery eleven.
Устройство работает следующим образом. 5The device operates as follows. 5
Включателем 10 включают электронагреватель 5 в работу, и в последний поступает ток от аккумуляторной батареи 11. При этом электронагреватель 5'разогревается и тепловой поток от него воздействует на термовыключатель 8. Под действием тепла после некоторого периода времени термовыключатель 8 срабатывает (*’перекидывается’'), подсоединяя цепь 7 электронагревателя 6. Электро- ’5 нагреватель 6 начинает излучать тепло, которое обеспечивает быстрый прогрев терморегулирующего органаThe switch 10 turns on the electric heater 5, and the last one receives the current from the battery 11. At the same time, the electric heater 5 'heats up and the heat flux from it acts on the thermal switch 8. Under the action of heat, after a certain period of time, the thermal switch 8 is activated (*' switches over ' ), connecting the circuit 7 of the electric heater 6. The electric '5 heater 6 begins to radiate heat, which provides a quick heating of the thermostatic organ
2. Затем, после заданного интервала времени, терморегулирующий орган 2 26 нагревается и полностью открывает воздушную заслонку. Электронагреватель 5 обеспечивает нагревание терморегулирующего органа 2 для перемещения воздушной заслонки в заданный 25 период времени, когда температура окружающей среда ниже рабочей температуры термовыключатёля. Благодаря применению в электронагревателях 5 и 6 материала с положительным температурным коэффициентом достигнуто саморегулирование нагревателя во избежание его перегрева и для снижения потребляемой мощности до минимального уровня после того, как устройство обеспечило нужное смещение заслонки. В случае, если температура окружающей среда выше рабочей температуры термовыключателя 8, электронагреватели 5 и 6 включаются одновременно, обеспечивая тем самым более быстрое открытие заслонки.2. Then, after a predetermined time interval, the thermostatic control 2 26 heats up and completely opens the air damper. The electric heater 5 provides heating of the thermostatic organ 2 to move the air damper for a predetermined 25 period of time, when the ambient temperature is lower than the operating temperature of the thermal switch. Due to the use of a material with a positive temperature coefficient in electric heaters 5 and 6, the self-regulation of the heater was achieved in order to avoid its overheating and to reduce power consumption to a minimum level after the device provided the necessary displacement of the damper. If the ambient temperature is higher than the operating temperature of the thermal switch 8, the electric heaters 5 and 6 are turned on simultaneously, thereby providing a faster opening of the damper.
Применение предлагаемого устройства обеспечивает более быстрое управление воздушной заслонкой карбюратора, снижая время работы двигателя на обогащенной топливо-воздушной смеси при различных температурах окружающей среда.The application of the proposed device provides faster control of the air damper of the carburetor, reducing the engine operating time on the enriched fuel-air mixture at various ambient temperatures.
