Description
Opis wynalazkuDescription of the invention
Przedmiotem wynalazku jest rozpylacz otworowy, stosowany jako zakończenie wtryskiwaczy paliwa zasilającego silniki spalinowe.The subject of the invention is a hole sprayer used as the end of fuel injectors feeding internal combustion engines.
Znane są dwa zasadnicze rodzaje rozpylaczy otworowych wtryskiwaczy, z których jedne wyposażone są w studzienkę, drugie zaś wyposażone są w gniazdo lecz bez względu na ich budowę mają one zapewnić dostarczenie strumienia paliwa do komory spalania silnika przez jego wtrysk pod wysokim ciśnieniem, które z racji zapewnienia dobrego rozpylenia paliwa i zmieszania go z powietrzem dochodzi nawet do wartości 205 MPa. Otwory wtryskiwaczy mają postać kanalików, które z reguły są wiercone elektroerozyjnie i są rozmieszczone w korpusie rozpylacza wewnątrz stożka strumienia, a ich liczba i średnica zależą od dawki wtrysku, kształtu komory spalania i intensywnoś ci zawirowania powietrza w komorze spalania. Rozpylacze muszą być starannie dobrane do danego rodzaju silnika. Przez właściwy dobór rozpylacza zostaje zapewnione prawidłowe dozowanie wtrysku - zależne od czasu trwania wtrysku oraz dawki wtrysku przypadającej na stopień obrotu wału korbowego, rozpylenie paliwa - zależne od liczby, kształtu i rozpylenia strumieni paliwa, rozdział paliwa w komorze spalania, szczelność komory spalania. W pompowtryskiwaczach i układach Common Rail rozpylacze są osadzone bezpośrednio we wtryskiwaczach, a krawędzie otworów wlotowych kanalików wtryskowych są zaokrąglone w celu zapobieżenia zużyciu krawędzi wywołanemu cząstkami ściernymi zawartymi w paliwie jak też zawężeniu tolerancji wydatku paliwa.There are two basic types of inlet nozzles for injectors, one of which is equipped with a well, the other is equipped with a socket, but regardless of their construction, they are to ensure the supply of the fuel stream to the combustion chamber of the engine by its injection under high pressure, which, due to good fuel atomization and mixing it with air can reach even 205 MPa. The injector holes are in the form of channels, which are usually drilled by electro-discharge and are arranged in the sprayer body inside the jet cone, and their number and diameter depend on the injection dose, the shape of the combustion chamber and the intensity of air turbulence in the combustion chamber. Nozzles must be carefully selected for the type of engine. The proper selection of the atomizer ensures correct injection dosing - depending on the injection duration and injection dose per crankshaft rotation degree, fuel atomization - depending on the number, shape and atomization of fuel jets, fuel distribution in the combustion chamber, tightness of the combustion chamber. In unit injectors and common rail systems, the nozzles are seated directly in the injectors, and the edges of the inlet ports of the injection channels are rounded to prevent edge wear caused by abrasive particles in the fuel and to narrow the fuel flow tolerance.
Z patentu francuskiego nr 392089 znana jest koń cówka wtryskiwacza wyposaż ona w kanaliki, przez które przepływa paliwo, przy czym strumienie paliwa po wyjściu z kanalików nie zderzają się i nie ma efektu rozpylenia paliwa poprzez wykorzystanie energii zderzenia strugi.French Patent No. 392089 discloses an injector tip equipped with channels through which the fuel flows, and the fuel jets after exiting the channels do not collide and there is no fuel atomization effect by using the jet collision energy.
Z patentu europejskiego nr EP 0446165 znany jest sposób elektrochemicznej obróbki otworów rozpylaczy i narzędzia do realizacji tego sposobu, przy czym poddawane obróbce otwory nie przecinają się.European Patent No. EP 0446165 discloses a method of electrochemical treatment of spray nozzles and tools for carrying out this method, the holes being treated do not intersect.
Z patentu US 6 186 419 znany jest rozpylacz, w którym struga paliwa z otworu wychodzącego prostopadle do osi rozpylacza, uderza w powierzchnię pierścienia umieszczonego na zewnątrz rozpylacza. Powierzchnia pierścienia jest nachylona do strugi pod kątem α.From the patent US 6,186,419 a sprayer is known, in which a stream of fuel from an opening perpendicular to the axis of the sprayer hits the surface of a ring located outside the sprayer. The surface of the ring is inclined to the stream at the angle α.
Z patentu GB 400.836 znana jest koń cówka wtryskiwacza wielootworowego, w której kanaliki rozmieszczone są na jej obwodzie. Takie rozmieszczenie kanalików wyklucza przecinanie się strumieni wytryskiwanego paliwa.From GB 400.836, the end of a multi-bore injector is known, in which the channels are arranged around its circumference. Such an arrangement of the channels excludes the intersection of the jets of the injected fuel.
Celem wynalazku jest skonstruowanie rozpylacza, który w momencie wtrysku paliwa do komory spalania silnika zapewni bardziej skuteczne jego rozpylenie przez uzyskanie mniejszych średnic kropelek paliwa oraz odpowiedni kąt bryłowy rozpylenia co pozwoli na znaczne podniesie sprawności silnika i czystości spalin.The aim of the invention is to construct an atomizer which, at the time of fuel injection into the engine combustion chamber, will ensure its more efficient atomization by obtaining smaller diameter of fuel droplets and an appropriate solid angle of atomization, which will significantly increase engine efficiency and exhaust gas purity.
Rozpylacz otworkowy, według wynalazku, ma zaokrąglone krawędzie otworów wlotowych i charakteryzuje się tym, ż e posiada w części stoż kowej korpusu usytuowane parami wylotowe otwory o jednakowych średnicach, których osie symetrii przecinają się na zewnątrz korpusu rozpylacza w komorze spalania, przy czym wylotowe otwory są zamykane przez jedną powierzchnię stożkową iglicy, a usytuowanie par wylotowych otworów na obwodzie stożkowej części korpusu jest równomierne.The pin-hole sprayer according to the invention has rounded edges of the inlet openings and is characterized by the fact that in the conical part of the body it has outlet openings of equal diameters arranged in pairs, the axes of symmetry of which cross outside the sprayer body in the combustion chamber, the outlet openings being closed by one conical surface of the needle, and the location of the pairs of outlet openings on the circumference of the conical part of the body is even.
Zaletą rozpylacza według wynalazku jest możliwość jego zastosowania we wszystkich znanych typach wtryskiwaczy, zwłaszcza we wtryskiwaczach ze studzienką i wtryskiwaczach z gniazdem, przy czym taka końcówka rozpylacza wykorzystując energię strumienia paliwa powoduje zdecydowaną poprawę jego rozpylenia, a strumienie oddziaływujące na siebie w przeciwfazie zwiększają energię wykorzystywaną równocześnie do lepszego rozpylenia paliwa. Zastosowanie rozwiązania według wynalazku umożliwia bezpośrednie zasilanie silnika paliwami organicznymi, zwłaszcza olejami organicznymi i alkoholami.The advantage of the atomiser according to the invention is the possibility of its use in all known types of injectors, especially in injectors with a well and in injectors with a socket, whereby such a tip of the atomizer, using the energy of the fuel stream, significantly improves its atomization, and the counter-phase jets increase the energy used at the same time. for better atomization of fuel. The use of the solution according to the invention makes it possible to supply the engine directly with organic fuels, in particular with organic oils and alcohols.
Przedmiot wynalazku został przedstawiony w przykładzie wykonania na rysunku, gdzie pokazano końcówkę rozpylacza z gniazdem z kątowo umieszczonymi otworami.The subject of the invention has been presented in the embodiment in the drawing, which shows the tip of the sprayer with a socket with angularly positioned holes.
Jak pokazano na rysunku rozpylacz otworkowy ma zaokrąglone krawędzie wlotowych otworów 3. W części stożkowej korpusu 1 rozpylacza otworkowego usytuowane są parami wlotowe otwory 3 o jednakowych średnicach, których osie symetrii przecinają się na zewnątrz korpusu 1 rozpylacza w komorze spalania. Wylotowe otwory 3 są zamykane przez jedną powierzchnię stożkową iglicy 2, a usytuowanie par wylotowych otworów 3 na obwodzie stożkowej części korpusu 1 jest równomierne.As shown in the drawing, the pinhole sprayer has rounded edges of the inlet holes 3. In the conical part of the body 1 of the pinhole sprayer there are inlet holes 3 of equal diameter in pairs, the axes of symmetry of which cross outside the sprayer body 1 in the combustion chamber. The outlet openings 3 are closed by one conical surface of the needle 2, and the positioning of the outlet openings 3 pairs on the circumference of the conical part of the body 1 is uniform.
