Description
Устройство для создания тяги отработанных газов в выхлопной трубе двигателя Предлагаемое изобретение относится к конструктивным элементам транспортных средств, а именно - к устройству для создания тяги отработанных газов в выхлопной трубе двигателя внутреннего сгорания транспортного средства. Device for creating exhaust gas traction in the exhaust pipe of an engine The present invention relates to structural elements of vehicles, namely, to a device for generating exhaust gas draft in an exhaust pipe of an internal combustion engine of a vehicle.
Наиболее близким к предлагаемому по достигаемому результату является устройство для создания тяги отработанных газов в выхлопной трубе двигателя внутреннего сгорания транспортного средства [Патент на изобретение N° 2227217, Россия, МПК 7 F01N7/20; Опубл.: 20.04.2004]. Указанное устройство содержит установленный на выхлопной трубе трубчатый элемент, выполненный с расширяющейся за срезом выхлопной трубы частью, на внутренней поверхности которой продольно расположены винтообразные канавки в виде "ласточкина хвоста", переходящие в круговую канавку у выходного отверстия трубчатого элемента. Изобретение направлено на повышение мощности двигателя путем создания в полости трубчатого элемента разрежения за счет использования набегающего быстрого потока воздуха для дополнительного отсоса отработанных газов из выхлопной трубы двигателя внутреннего сгорания транспортного средства при определенных скоростях движения. Closest to the proposed achieved result is a device for creating exhaust gas traction in the exhaust pipe of an internal combustion engine of a vehicle [Patent for invention N ° 2227217, Russia, IPC 7 F01N7 / 20; Published: 04/20/2004]. The specified device contains a tubular element mounted on the exhaust pipe, made with a part extending beyond the tail section of the exhaust pipe, on the inner surface of which are helical grooves in the form of a "dovetail" longitudinally passing into a circular groove at the outlet of the tubular element. The invention is aimed at increasing engine power by creating a vacuum in the cavity of the tubular element through the use of an oncoming fast air flow for additional exhaust exhaust from the exhaust pipe of the vehicle’s internal combustion engine at certain speeds.
Описанное устройство может способствовать повышению мощности двигателя внутреннего сгорания транспортного средства - автомобиля, но такое повышение является недостаточно эффективным из-за создания кузовом автомобиля дополнительной помехи набегающему потоку воздуха, что ухудшает вентиляцию в цилиндрах двигателя внутреннего сгорания транспортного средства. Это особенно ощутимо во время необходимости существенного увеличения мощности в начале движения и при скоростях меньше 30-40 километров в час. The described device can help increase the power of the internal combustion engine of the vehicle — the car, but this increase is not effective enough due to the body of the car creating additional interference with the incoming air flow, which impairs ventilation in the cylinders of the internal combustion engine of the vehicle. This is especially noticeable when you need a significant increase in power at the beginning of movement and at speeds less than 30-40 kilometers per hour.
В основу предлагаемого изобретения поставлена задача разработки такого устройства для создания тяги отработанных газов в выхлопной системе двигателя внутреннего сгорания транспортного средства, которое было бы более эффективным за счет создания условий для принудительного разрежения
отработанных газов в выхлопной трубе двигателя внутреннего сгорания транспортного средства и не зависело бы от скорости набегающего на транспортное средство потока воздуха, что, как следствие, способствовало бы повышению тяги отработанных газов в выхлопной трубе и улучшению вентиляции цилиндров двигателя в процессе его работы на разных режимах. The basis of the invention is the task of developing such a device for creating exhaust gas traction in the exhaust system of an internal combustion engine of a vehicle, which would be more effective by creating conditions for forced rarefaction the exhaust gases in the exhaust pipe of the vehicle’s internal combustion engine and would not depend on the speed of the air flow incident on the vehicle, which, as a result, would increase the exhaust gas thrust in the exhaust pipe and improve the ventilation of the engine cylinders during its operation in different modes.
Предлагаемое устройство для создания тяги отработанных газов в выхлопной трубе двигателя внутреннего сгорания транспортного средства, согласно изобретению, выполнено в виде струйного эжектора, который включает воздушную турбину с электроприводом, вход которой предназначен для соединения с окружающей атмосферой, а на выходе воздушной турбины установлено сопло, предназначенное для его размещения в полости выхлопной трубы с возможностью смешивания потоков выхлопных газов и воздуха с воздушной турбины. The proposed device for generating exhaust gas thrust in the exhaust pipe of an internal combustion engine of a vehicle, according to the invention, is made in the form of a jet ejector, which includes an electric air turbine, the input of which is designed to connect with the surrounding atmosphere, and a nozzle is installed at the output of the air turbine for its placement in the cavity of the exhaust pipe with the possibility of mixing the flow of exhaust gases and air from an air turbine.
Особенностью предлагаемого устройства является и то, что оно дополнено системой запуска-выключения электрического привода воздушной турбины. A feature of the proposed device is that it is supplemented by a start-off system for an electric drive of an air turbine.
В качестве основы предлагаемого устройства для создания тяги отработанных газов может быть использован традиционный газо-газовый эжектор - струйный элемент. В предлагаемом устройстве давление газа одного (пассивного) потока выхлопных газов увеличивается за счет его смешивания с другим (активным) потоком - потоком воздуха более высокого давления, а за счет обеспечения воздушной турбины струйного элемента электрическим приводом происходит непрерывное принудительное удаление создаваемой смеси из полости выхлопной трубы. As a basis of the proposed device for creating exhaust gas traction, a traditional gas-gas ejector - a jet element can be used. In the proposed device, the gas pressure of one (passive) stream of exhaust gases increases due to its mixing with another (active) stream - a stream of higher pressure air, and due to the provision of an air turbine of the jet element with an electric drive, continuous forced removal of the created mixture from the cavity of the exhaust pipe occurs .
Сопло, установленное на выходе эжектора, предназначено для повышения скорости активного (эжектирующего) потока, направленного на смешивание с пассивным потоком. The nozzle installed at the outlet of the ejector is designed to increase the speed of the active (ejection) stream, aimed at mixing with a passive stream.
Предлагаемое устройство более эффективно, чем устройство-прототип, поскольку в нем созданы условия для принудительного разрежения отработанных газов в выхлопной трубе двигателя внутреннего сгорания транспортного средства, что направлено на повышение тяги отработанных газов в выхлопной трубе и на улучшение вентиляции цилиндров двигателя, который работает на низких оборотах.
Наличие в устройстве воздушной турбины с управляемым соответствующей системой электрическим приводом позволяет водителю транспортного средства получать во время работы двигателя увеличенную мощность, что повышает безопасность на дороге. А улучшение вентиляции цилиндров двигателя, который работает на низких оборотах, улучшает условия горения топлива и уменьшает количество вредных выбросов в атмосферу. The proposed device is more efficient than the prototype device, because it creates conditions for forced rarefaction of exhaust gases in the exhaust pipe of an internal combustion engine of a vehicle, which is aimed at increasing the draft of exhaust gases in the exhaust pipe and improving ventilation of the engine cylinders, which operates at low revolutions. The presence in the device of an air turbine with an electric drive controlled by the corresponding system allows the driver of the vehicle to receive increased power during engine operation, which increases road safety. And improving the ventilation of the cylinders of the engine, which operates at low speeds, improves the combustion conditions of the fuel and reduces the amount of harmful emissions into the atmosphere.
Во время проведения патентно-информационных исследований при подготовке настоящей заявки авторами не обнаружены устройства для создания тяги отработанных газов в выхлопной системе двигателя внутреннего сгорания транспортного средства предлагаемой конструкции с указанной выше совокупностью существенных признаков, что доказывает соответствие заявляемого технического решения критерию изобретения "новизна". During the conduct of patent information research in the preparation of this application, the authors did not find a device for creating exhaust gas traction in the exhaust system of an internal combustion engine of a vehicle of the proposed design with the above set of essential features, which proves that the claimed technical solution meets the criteria of the invention of "novelty".
Технический результат, полученный в результате осуществления предлагаемого изобретения, состоит в создании условий для принудительного непрерывного - в процессе работы двигателя внутреннего сгорания - разрежения отработанных газов в выхлопной трубе двигателя внутреннего сгорания транспортного средства, которое не зависит от скорости набегающего на транспортное средство потока воздуха. За счет принудительного непрерывного разрежения отработанных газов в выхлопной трубе происходит лучшее наполнение цилиндров свежей топливо-воздушной смесью, что эквивалентно увеличению давления наддува и, как следствие, способствует повышению тяги отработанных газов в выхлопной трубе и улучшению вентиляции цилиндров двигателя в процессе его работы на разных режимах. Улучшение же вентиляции цилиндров двигателя, который работает на низких оборотах, например при стоянке автомобиля у светофора, улучшает условия горения топлива и уменьшает количество вредных выбросов в атмосферу. The technical result obtained as a result of the implementation of the present invention is to create conditions for the continuous continuous — during operation of the internal combustion engine — rarefaction of exhaust gases in the exhaust pipe of the vehicle’s internal combustion engine, which does not depend on the speed of the air flow incident on the vehicle. Due to the forced continuous rarefaction of the exhaust gases in the exhaust pipe, the cylinders are better filled with fresh fuel-air mixture, which is equivalent to an increase in boost pressure and, as a result, increases the exhaust gas draft in the exhaust pipe and improves the ventilation of the engine cylinders during its operation at different modes . Improving the ventilation of engine cylinders, which operates at low speeds, for example, when the car is parked at a traffic light, improves the combustion conditions of the fuel and reduces the amount of harmful emissions into the atmosphere.
Указанный технический результат в известных технических решениях, которые вошли в уровень техники, авторами не выявлен, поэтому предлагаемое устройство может быть признано соответствующим критерию изобретения "изобретательский уровень". The specified technical result in the known technical solutions that are included in the prior art, the authors have not identified, therefore, the proposed device can be recognized as meeting the criteria of the invention "inventive step".
Предлагаемое устройство состоит из конструктивных элементов, для изготовления которых используют известные на сегодняшний день
технологические приемы, устройства и материалы. Устройство для создания тяги отработанных газов в выхлопной системе двигателя внутреннего сгорания транспортного средства предлагаемой конструкции может быть использовано в транспортных средствах в различных отраслях промышленности, сельского хозяйства, обороны и на транспорте, поэтому можно сделать вывод о том, что предлагаемое решение соответствует критерию изобретения «промышленная применимость». The proposed device consists of structural elements, for the manufacture of which use the currently known technological methods, devices and materials. A device for generating exhaust gas thrust in the exhaust system of an internal combustion engine of a vehicle of the proposed design can be used in vehicles in various industries, agriculture, defense and transport, so we can conclude that the proposed solution meets the criteria of the invention “industrial applicability".
Сущность предлагаемого устройства объясняется схематическим чертежом (фиг.1). The essence of the proposed device is explained by a schematic drawing (figure 1).
Предлагаемое устройство для создания тяги отработанных газов в выхлопной трубе двигателя внутреннего сгорания транспортного средства выполнено в виде струйного эжектора. Струйный эжектор запускает воздушную турбину 1 , установленную на валу электрического привода 2. Вход турбины 1 соединен с окружающим воздухом, а на ее выходе установлено сопло 3 в виде усеченного конуса, размещенное в полости выхлопной трубы 4 автомобиля. Сопло 3 закреплено на входе трубы Вентури 5. The proposed device for creating a draft of exhaust gases in the exhaust pipe of an internal combustion engine of a vehicle is made in the form of a jet ejector. The jet ejector starts an air turbine 1 mounted on the shaft of the electric drive 2. The inlet of the turbine 1 is connected to the surrounding air, and a nozzle 3 in the form of a truncated cone is placed in the cavity of the exhaust pipe 4 of the car at its outlet. The nozzle 3 is fixed at the inlet of the venturi 5.
В основе принципа действия трубы Вентури лежит эффект Вентури— явление уменьшения давления в потоке жидкости или газа, когда этот поток проходит через суженный участок трубы [информация с сайта http://ru.wikipedia.org/wiki/%D0%A2%D 1 %80%D1 %83%D0%B 1 %D0%B0_%D0%9 2%D0%B5%D0%BD%D 1 %82%D 1 %83%D 1 %80%D0%B8 ] . The Venturi effect is based on the Venturi effect — the phenomenon of a decrease in pressure in a liquid or gas stream when this stream passes through a narrowed section of the pipe [information from the site http://ru.wikipedia.org/wiki/%D0%A2%D 1 % 80% D1% 83% D0% B 1% D0% B0_% D0% 9 2% D0% B5% D0% BD% D 1% 82% D 1% 83% D 1% 80% D0% B8].
Корпус и лопасти турбины 1 могут быть изготовлены из пластика. Устройство снабжено системой запуска-выключения электрического привода 2 воздушной турбины 1. В качестве электрического привода 2 может быть использован, например, скоростной электрический двигатель постоянного тока мощностью примерно 200-250 Ватт. Указанная система запуска включает источник питания - автомобильный аккумулятор, выход которого соединен с электрическим приводом 2 турбины 1 через блок запуска, который содержит один замыкающий контакт и управляется дистанционно из кабины водителя /не показано/. Вместо замыкающего контакта может быть установлен другой коммутационный элемент, установленный с возможностью управления
оборотами скоростного электрического двигателя, увеличивая их при увеличении числа оборотов двигателя внутреннего сгорания транспортного средства. The housing and blades of the turbine 1 can be made of plastic. The device is equipped with a start-off system for the electric drive 2 of the air turbine 1. As an electric drive 2, for example, a high-speed direct current electric motor with a power of about 200-250 watts can be used. The specified start-up system includes a power source - a car battery, the output of which is connected to the electric drive 2 of the turbine 1 through the start-up block, which contains one make contact and is remotely controlled from the driver’s cab / not shown /. Instead of a make contact, another switching element can be installed that can be controlled revolutions of a high-speed electric engine, increasing them with increasing speed of the vehicle’s internal combustion engine
Предлагаемое устройство работает так. После запуска двигателя внутреннего сгорания транспортного средства водитель автомобиля включает электрический привод 2. При этом электрический привод 2 получает питание от аккумулятора и начинает вращать вал с турбиной 1. Лопасти турбины 1 создают скоростной поток воздуха на выходе сопла 3. Поток проходит через трубу Вентури 5 и, как следствие, создает разрежение в полости выхлопной трубы 4, повышая в ней тягу отработанных газов и улучшая вентиляцию цилиндров двигателя. Таким образом, предлагаемое устройство является более эффективным, чем устройство-прототип за счет искусственного разрежения отработанных газов в выхлопной трубе 4, которое не зависит от скорости набегающего на автомобиль потока воздуха, что способствует повышению тяги отработанных газов в выхлопной трубе 4 и улучшает вентиляцию цилиндров двигателя. The proposed device works like this. After starting the vehicle’s internal combustion engine, the car driver turns on the electric drive 2. At the same time, the electric drive 2 receives power from the battery and starts to rotate the shaft with the turbine 1. The blades of the turbine 1 create a high-speed air flow at the exit of the nozzle 3. The flow passes through the venturi 5 and as a result, creates a vacuum in the cavity of the exhaust pipe 4, increasing the exhaust gas thrust in it and improving the ventilation of the engine cylinders. Thus, the proposed device is more efficient than the prototype device due to the artificial rarefaction of the exhaust gases in the exhaust pipe 4, which does not depend on the speed of the incoming air flow on the car, which helps to increase the draft of exhaust gases in the exhaust pipe 4 and improves the ventilation of the engine cylinders .
При этом поломка какого-либо элемента предлагаемого устройства не сказывается на безопасности движения транспортного средства.
In this case, the breakdown of any element of the proposed device does not affect the safety of the vehicle.
