Description
Существующие способы предупреждени взрывов паров масла в картерах двигателей внутреннего сгорани предусматривают вентил цию картеров отработанными в двигателе газами путем подачи их в картер при помощи насосов. Однако применение насосов усложн ет эксплуатацию двигател и ухудшает экономичность его работы.Existing methods to prevent oil vapor explosions in crankcases of internal combustion engines provide for ventilation of crankcases with exhaust gases in the engine by injecting them into the crankcase using pumps. However, the use of pumps complicates the operation of the engine and impairs the efficiency of its operation.
Особенностью изобретени вл етс использование дл подачи и отсоса газов из картера избыточного давлени и скоростного напора отход щих газов двигател , вследствие чего повышаетс надежность и экономичность работы последнего.A feature of the invention is the use for supplying and suction of gases from the crankcase overpressure and velocity head of engine exhaust gases, as a result of which the reliability and economy of the latter is improved.
На чертеже приведен пример применени предлагаемого способа предотвращени взрывов паров масла в закрытых картерах двигателей внутреннего сгорани .The drawing shows an example of the application of the proposed method for preventing oil vapor explosions in closed crankcases of internal combustion engines.
Выхлопные газы двигател по трубопроводу / направл ютс в глушитель 2. Часть этих газов отбираетс в трубу 3 и пропускаетс через дроссельную шайбу 4 и мокрый очиститель 5, вода в которыйThe engine exhaust gases are piped / directed to muffler 2. Some of these gases are drawn into duct 3 and passed through throttle washer 4 and wet cleaner 5, water in which
подаетс из водопровода 6. Пройд затем сухой очиститель 7, охлажденные и очищенные газы по трубопроводу 8 направл ютс в картер 9 двигател .It is supplied from the water line 6. Then pass the dry cleaner 7, cooled and cleaned gases through the pipe 8 are sent to the crankcase 9 of the engine.
Проход через картер, выхлопные газы снижают концентрацию кислорода в смеси паров масла и воздуха в картере и унос т с собой некоторое количество углеводородов , осундествл таким образом вентил цию картера.The passage through the crankcase, exhaust gases reduce the oxygen concentration in the mixture of oil and air vapor in the crankcase and carry off some of the hydrocarbons, thus removing the crankcase ventilation.
Из картера выхлопные газы отвод тс выводной трубой 10 с инжектором 11 на конце в выхлопной трубопровод двигател за счет разр жени , создаваемого в этой трубе благодар инжектирующемус свойству скоростного потока.From the crankcase, exhaust gases are diverted by an outlet pipe 10 with an injector 11 at the end into the engine exhaust pipe due to the discharge created in this pipe due to the injecting property of the velocity stream.
Дл предотвращени уноса масла в выводно трубе устанавливаютс маслоотбойные пластины. Количество газов, проход щих через картер, автоматически регулируетс самим двигателем, увеличива сь с увеличением нагрузки двигател . № 108548 Предмет изобретени Способ предотвращени взрывов паров масла в закрытых картерах двигателей впутреннего сгорани , при котором из картера с одной стороны отсасываютс , а с другой стороны в картер нагнетаютс очищенные и охлажденные газы, отличающийс тем, что дл указанного отсоса и подачи газов используютс избыточное давление и скоростной напор отход щих газов двигател .To prevent the oil from being carried off, oil breakers are installed in the discharge pipe. The amount of gases passing through the crankcase is automatically controlled by the engine itself, increasing with increasing engine load. No. 108548 Subject of the Invention A method for preventing oil vapor explosions in closed crankcases of internal combustion engines in which purified and cooled gases are injected from the crankcase on one side and purified and cooled gases are injected into the crankcase, characterized in that excess pressure is used for the suction and gas supply and engine exhaust gas velocity.
