Description

447 153 2 Genom sådana åtgärder undviks isbildning hos förângaren- regulatorn vid kallstartfasen av förbränningsmotorn, i synnerhet då uppvärmningen av förångaren genom varmt kylmedel ännu icke är verksam. Såsnart kylmedlet efter igångsättningen av motorn har upp- nått en för uppvärmning av förångaren tillräcklig temperatur, sätts den elektriska uppvärmningen ur funktion. 447 153 2 Such measures avoid the formation of ice on the evaporator regulator during the cold start phase of the internal combustion engine, in particular when the heating of the evaporator by hot coolant is not yet effective. As soon as the coolant after starting the engine has reached a temperature sufficient for heating the evaporator, the electric heating is deactivated.

Den elektriska uppvärmningen medelst ett i förångaren anord- nat värmeelement ersätter följaktligen icke den sedvanliga kylvatten- uppvärmningen, utan kompletterar denna i kritiska faser.The electric heating by means of a heating element arranged in the evaporator consequently does not replace the usual cooling water heating, but complements it in critical phases.

Vid en föredragen utföringsform av uppfinningen kan uppvärm- ningselementet utgöras av ett självreglerande snabbglödstift.In a preferred embodiment of the invention, the heating element can be constituted by a self-regulating rapid glow plug.

!Uppfinningen beskrives närmare nedan under hänvisning till bifogade ritning. ß :Genom det i en tryckbehållare 1 rådande övertrycket matas flytande gas till en kombinerad förångare och regulator 2 och för- ångas och expanderas där i två steg.The invention is described in more detail below with reference to the accompanying drawing. ß: Through the overpressure prevailing in a pressure vessel 1, liquefied gas is fed to a combined evaporator and regulator 2 and evaporated and expanded there in two steps.

Den i förångarregulatorn 2 inträdande flytande gasen tryck- reduceras där genom en icke närmare visad tryckminskningsventil till 125-1ÄO kPa (första regleringssteget) och leds genom en labyrint, som omspolas av varmt kylvatten. Det varma vattnet tas från motorns 3 kylsystem. Från vattnet upptar gasen den för förångningen erfor- derliga värmemängden. En huvudventil Ä i det andra regleringssteget styrs via ett huvudmembran 5 genom ett i ventilröret hos blandnings- anordningen 6 uppmätt undertryck och avger en mot luftflödet i insugningsröret 7 svarande gasvolym. I(blandningsanordningen 6, som är anordnad före motorns 3 spjäll 8, införs gasen i insugningsluften.The liquefied gas entering the evaporator regulator 2 is reduced in pressure there through a pressure relief valve (not shown) to 125-1ÄO kPa (first control step) and passed through a labyrinth, which is flushed by hot cooling water. The hot water is taken from the engine's 3 cooling system. From the water, the gas absorbs the amount of heat required for evaporation. A main valve Ä in the second control stage is controlled via a main diaphragm 5 by a negative pressure measured in the valve pipe of the mixing device 6 and emits a gas volume corresponding to the air flow in the intake pipe 7. In the mixing device 6, which is arranged before the damper 8 of the engine 3, the gas is introduced into the intake air.

Under motorns kallstartfas har kylvattnet ännu icke blivit uppvärmt. Ett elektriskt värmeelement 9 är därför anordnat i för- ångaren-regulatorn 2, närmare bestämt i strömningsvägen för motor- kylvattnet i närheten av den mest utsatta huvudventilen 4.During the cold start phase of the engine, the cooling water has not yet been heated. An electric heating element 9 is therefore arranged in the evaporator regulator 2, more specifically in the flow path of the engine cooling water in the vicinity of the most exposed main valve 4.

Härigenom undviks vid kallstart vid låg omgivnings- temperatur blockering av huvudventilen genom isbildning. Värme- elementet 9 består av ettvid huset 10 till förångaren-regulatorn 2 fäst och i kylvattenströmmen inskjutande självreglerande snabbglöd- stift i stavform, som enbart är verksam vid och kort efter kall- I startfasen. Stavglödstiftet kan emellertid även aktiveras genom temperatur- och/eller tidberoende arbetande element. Vidare kan den elektriska regleringen åstadkommas manuellt över en tryck- knapp.This avoids blocking of the main valve due to icing during cold starts at low ambient temperatures. The heating element 9 consists of a self-regulating self-regulating instant glow pin in rod form attached to the housing 10 to the evaporator regulator 2 and which is inserted into the cooling water stream, which only acts at and shortly after the cold start phase. However, the glow plug can also be activated by temperature- and / or time-dependent working elements. Furthermore, the electrical control can be accomplished manually via a push button.

' Som värmeelement kan emellertid även vara anordnade mot-However, counter-heating elements can also be provided as heating elements.
