Description

IskumäntäpolttomoottorikoneReciprocating piston internal combustion engine

Keksintö koskee iskumäntäpolttomoottorikonetta, joka on sopiva raskasöljykäytölle, jossa iskumäntäpolttomoottorikoneessa on polttoainetta korkealla paineella johtava polttoaineen säännöstelysyöttöjohto suihkutusvent-5 tiilien syöttämiseksi.The invention relates to a piston internal combustion engine machine suitable for use in heavy oil, wherein the piston internal combustion engine has a high-pressure fuel-regulating fuel feed line for supplying the jet vent bricks.

Keksinnön tarkoituksena on lisätä iskumäntäpolttomoottorikoneen käytettävyyttä yksinkertaisin, tilaa säästävin keinoin.The object of the invention is to increase the usability of the percussion piston engine machine by simple, space-saving means.

Tämä tarkoitus ratkaistaan siten, että polttoaineen säännöstelysyöt-töjohtoon on sijoitettu kuumennuselementti. Keksintöä sovellettaessa suihku-10 tusventtiileissä voi aina olla odottamassa polttoainetta, jolla on vaadittava lämpötila ja siten vaadittava viskositeetti. Kone voidaan käynnistää ongelmitta myös seisokkivaiheen jälkeen. Myös käytössä edistetään polttoaineen vaadittavan viskositeetin noudattamista.This object is solved by placing a heating element in the fuel control feed line. In the practice of the invention, the jet valve 10 may always be waiting for a fuel having the required temperature and thus the required viscosity. The machine can be started without problems even after the shutdown phase. Also in use, compliance with the required fuel viscosity is promoted.

Kuumennuselementti on järjestetty keskeisesti polttoaineen sään-15 nöstelysyöttöjohtoon. Tämän avulla saavutetaan johdetun lämmön optimaalinen hyväksikäyttäminen.The heating element is centrally arranged in the fuel weathering supply line. This results in optimum utilization of the conducted heat.

Polttoaineen säännöstelysyöttöjohto on edullisesti vaipoitettu sisällyttäen mukaan ilmarako. Täten lämpöhävikki voidaan minimoida.The fuel control feed line is preferably jacketed including an air gap. Thus, heat loss can be minimized.

Lisää tunnusmerkkejä ja etuja käy ilmi lisäksi olevista epäitsenäisis-20 tä patenttivaatimuksista ja piirustuksen avulla olevan suoritusesimerkin selityksestä. Piirustus esittää polttoaineen säännöstelysyöttöjohdon osan siihen liittyvien osien kanssa leikkauskuvassa.Further features and advantages will be apparent from the additional dependent claims and from the description of an exemplary embodiment by way of the drawing. The drawing shows a section of the fuel control feed line with its associated parts in sectional view.

Piirustuksessa putkimaisesti toteutettu polttoaineen säännöstelysyöttöjohto on esitetty merkillä 1. Sisätilaan 2, joka ottaa vastaan korkeassa 25 paineessa olevan polttoaineen, on sijoitettu kuumennuselementti 3. Kuumensi nuselementti on esitetyssä suoritusesimerkissä muodostettu tulistetulla höyryl- S1 lä paineistetuksi putkeksi. Polttoaineen säännöstelysyöttöjohdon 1 molempiinIn the drawing, a tubular fuel control fuel feed line is shown as 1. A heating element 3 is disposed in the interior 2, which receives the fuel under high pressure, and the hot element is formed in the embodiment shown as a superheated steam S1 pipe. Fuel control feed line 1 to both

LOLO

o päihin on kuhunkin sijoitettu sulkukappale 4, joka sulkee sisätilan 2 painetiiviis- ^ ti. Piirustuksessa on esitetty vain toinen sulkukappale 4. Jokainen sulkukappa- 30 le 4 käsittää ei-esitetyn porausaukon 5, johon ei-esitetyt putkijohdot on liitetty tulistetun höyryn kiertämisen kunnossa pitämiseksi. Kuumennuselementti 3 ja $2 porausaukko 5 on tällöin toteutettu painetiiviisti sisätilaa 2 vastapäätä. Poltto- g aineen säännöstelysyöttöjohto 1 on sinänsä tunnetulla tavalla liitoskappaleissa ° 6 olevien porausaukkojen ja kunkin liittävän putkijohdon 7 kautta yhteydessä 35 kunkin suihkutusventtiilin 8 kanssa. Kahden liitoskappaleen 6 tai yhden liitos-kappaleen 6 ja sulkukappaleen 4 väliin on järjestetty polttoaineen säännöste- 2 lysyöttöjohdon ympärille kulloinkin vaippaputkikappale 9 sisällyttäen mukaan ilmarako.o at each end there is a sealing piece 4 which seals the interior 2 in a pressure-tight manner. Only one barrier member 4 is shown in the drawing. Each barrier member 4 comprises a non-shown borehole 5 to which non-shown conduits are connected to maintain the circulation of superheated steam. The heating element 3 and the bore hole 5 of the $ 2 are then pressurized against the interior 2. In a manner known per se, the fuel control feed line 1 is connected via boreholes in the connection pieces 6 and each connecting pipe 7 with each spray valve 8. Between the two connecting pieces 6 or one connecting piece 6 and the closing piece 4 are arranged around the fuel control feed line 2, each with a diaphragm tube piece 9 including an air gap.

Tulistetulla höyryllä läpivirtaaman kuumennuselementin sijasta voidaan käyttää myös sähköistä kuumennuselementtiä.Instead of the heating element flowing with superheated steam, an electric heating element can also be used.

5 Edellä selitetyn kuumennuselementin avulla on mahdollista raken- netilan ollessa pieni esilämmittää polttoaine polttoaineen säännöstelysyöttö-johdossa 1 tasaisesti ja sen avulla taata varma moottorin käynnistys ja moottorin toiminta raskasöljyllä. Lisäksi lyhenee aika iskumäntäpolttomoottorikoneen käytettävyyteen asti, koska vaadittava aikaväli lyhenee, jotta päästään kylmäsit) tä koneesta käyttöselvään koneeseen asti.5 With the heating element described above, it is possible to preheat the fuel in the fuel control feed line 1 evenly with a small structural space and thereby ensure reliable engine starting and engine operation with heavy oil. In addition, the time to the availability of the percussion piston engine engine is reduced as the time required to reach the cold machine from the machine to the machine is shortened.
