ВАРИАНТ ОСУЩЕСТВЛЕНИЯ ИЗОБРЕТЕНИЯ MODE FOR CARRYING OUT THE INVENTION
Устройство содержит рабочий цилиндр 2 с рабочим поршнем 1. В рабочем цилиндре 2 выполнены впускной клапан 4 и выпускной клапан 3. The device comprises a working cylinder 2 with a working piston 1. In the working cylinder 2, an inlet valve 4 and an exhaust valve 3 are made.
Рабочий цилиндр 2 соединен с подстроенным цилиндром 5, внутри которого расположен подстроечный поршень 6 со штоком 7. Противоположная часть подстроечного цилиндра 5 соединена с регулирующей камерой 8, которая обеспечена диафрагмой 9. Диафрагма 9 соединена со штоком 7 подстроечного поршня 6. Регулирующая камера 8 также соединена с распределительной камерой 12 и регулирующим жиклером 11. Внутри распределительной камеры 12 установлены прямой клапан 18 и обратный клапан 17. С помощью трубопровода 13 распределительная камера 12 соединена с регулирующим жиклером 11, а с помощью трубопровода 10 она соединена с регулирующим ресивером 19, который снабжен поршнем 20. The working cylinder 2 is connected to the trimmed cylinder 5, inside which there is a trimming piston 6 with the rod 7. The opposite part of the trimming cylinder 5 is connected to the control chamber 8, which is provided with a diaphragm 9. The diaphragm 9 is connected to the rod 7 of the trimming piston 6. The control chamber 8 is also connected with a distribution chamber 12 and a control nozzle 11. Inside the distribution chamber 12, a direct valve 18 and a check valve 17 are installed. Using a pipe 13, the distribution chamber 12 is connected to the control the nozzle 11, and with the help of the pipeline 10 it is connected to the control receiver 19, which is equipped with a piston 20.
Распределительная камера 12 также соединена трубопроводом 14 с общим ресивером 16. На трубопроводе 14 установлен регулятор давления 15. The distribution chamber 12 is also connected by a pipe 14 to a common receiver 16. A pressure regulator 15 is installed on the pipe 14.
Устройство для регулирования степени сжатия поршневого двигателя внутреннего сгорания работает следующим образом. A device for controlling the compression ratio of a reciprocating internal combustion engine operates as follows.
Перед запуском двигателя воздух из общего ресивера 16 через регулятор давления 15 и трубопровод 14 подается в распределительную камеру 12 и дальше через прямой клапан 18 и трубопровод 10 поступает в регулирующий ресивер 19, а также через трубопровод 13 поступает в регулирующий жиклер 11 и дальше в регулирующую камеру 8. При этом обратный клапан 17 будет закрыт. Before starting the engine, air from the common receiver 16 through the pressure regulator 15 and the pipe 14 is supplied to the distribution chamber 12 and then through the direct valve 18 and the pipe 10 enters the control receiver 19, and also through the pipe 13 enters the control nozzle 11 and then into the control chamber 8. In this case, the check valve 17 will be closed.
При запуске двигателя давление в рабочем цилиндре 2 будет подниматься, вследствие чего будет подниматься и подстроечный поршень 6, который с помощью штока 7 будет поднимать диафрагму 9. При этом воздух из регулирующей камеры 8 будет выталкиваться через обратный клапан 17 и регулирующий жиклер 11 , а прямой клапан 18 будет закрываться. When the engine starts, the pressure in the working cylinder 2 will rise, as a result of which the trimming piston 6 will also rise, which with the help of the rod 7 will raise the diaphragm 9. In this case, air from the control chamber 8 will be pushed through the check valve 17 and the control nozzle 11, and the straight valve 18 will close.
При движении рабочего поршня 1 вниз в рабочем цилиндре 2 давление
упадет, и подстроечный поршень 6 опустится, при этом закроется обратный клапан 17 и воздух из распределительной камеры 12 будет поступать в регулирующую камеру 8 только через регулирующий жиклер 11. When the working piston 1 moves down in the working cylinder 2, the pressure it will fall, and the trimming piston 6 will lower, and the check valve 17 will be closed and air from the distribution chamber 12 will enter the control chamber 8 only through the control nozzle 11.
Диаметр проходного отверстия регулирующего жиклера 11 подбирается таким, чтобы при холостых оборотах двигателя подстроечный поршень 6 успевал полностью опуститься - при этом будет максимальная степень сжатия в рабочем цилиндре 2, а при максимальных оборотах двигателя подстроечный поршень 6 не успевал бы опуститься и зависал в верхнем положении - это будет отвечать минимальной степени сжатия в рабочем цилиндре 2. Такой режим изменения степени сжатия отвечает самым оптимальным условиям работы двигателя, и этот режим обеспечивает максимальный коэффициент полезного действия. The diameter of the bore of the regulating nozzle 11 is selected so that at idle the trimmer piston 6 has time to completely lower - at the same time there will be a maximum compression ratio in the working cylinder 2, and at maximum rotational speeds of the trimmer piston 6 would not have time to fall and hang in the upper position - this will correspond to the minimum compression ratio in the working cylinder 2. This mode of changing the compression ratio meets the most optimal engine operating conditions, and this mode provides the maximum athletic efficiency.
Изменяя объем регулирующего ресивера 19 при движении подстроенного поршня 6 вверх диафрагма 9 выталкивает воздух в распределительную камеру 12 сквозь обратный клапан 17; соответственно прямой клапан 18 закроется. Changing the volume of the regulating receiver 19 when the trimmed piston 6 moves upward, the diaphragm 9 pushes air into the distribution chamber 12 through the check valve 17; accordingly, the direct valve 18 closes.
При минимальном объеме воздуха в регулирующем ресивере 19 и положении рабочего поршня 2 в верхней мертвой точке давление в распределительной камере 12 будет максимальным и при этом подстроечный поршень 6 опустится максимально близко к рабочему поршню 1, что приведет к повышению степени сжатия в рабочем цилиндре 2 и такая работа двигателя будет жесткой. При увеличении объема регулирующего ресивера 19 степень сжатия будет уменьшена и такая работа двигателя будет мягкой. With a minimum amount of air in the control receiver 19 and the position of the working piston 2 at top dead center, the pressure in the distribution chamber 12 will be maximum and the trimmer piston 6 will drop as close as possible to the working piston 1, which will increase the compression ratio in the working cylinder 2 and such engine operation will be tough. With an increase in the volume of the control receiver 19, the compression ratio will be reduced and this engine operation will be soft.
Такое двойное регулирование степени сжатия дает возможность использовать различное топливо, которое будет сгорать в оптимальном режиме на всех режимах работы двигателя внутреннего сгорания, и зажигать топливную смесь как свечой, так и сжатием. Давление в трубопроводе 14 задается таким, чтобы степень сжатия в камере сгорания отвечала рекомендованному значению для конкретного топлива. Such a double regulation of the compression ratio makes it possible to use various fuels, which will burn in the optimum mode in all operating modes of the internal combustion engine, and ignite the fuel mixture with both a candle and compression. The pressure in the pipe 14 is set so that the compression ratio in the combustion chamber meets the recommended value for a particular fuel.
Устройство может использоваться как на четырехтактных, так и на двухтактных двигателях. Вместо регулирующей камеры с диафрагмой можно
использовать цилиндр с поршнем. The device can be used on both four-stroke and two-stroke engines. Instead of a diaphragm control chamber, you can use a cylinder with a piston.
На малооборотных двигателях вместо воздуха можно использовать жидкость. On slow-speed engines, liquid can be used instead of air.
