Description

Innretning til måling av spyleluft- og avgasstrykk ved stempelforbrenningsmotorer. Device for measuring scavenge air and exhaust gas pressure in reciprocating combustion engines.

Denne oppfinnelse vedrører en innretning til måling av spyleluft- og avgasstrykk ved stempelforbrenningsmotorer med oppladning, særlig ved totaktmotorer med liketrykkopplading. Mens ved ikke oppladede motorer spylelufttrykket er et direkte mål for innløps- og utløpskanalenes tilsmussing, særlig av en totaktmotors slis-ser, måles tilsmussingen ved oppladede motorer ved trykkdifferansen mellom spylelufttrykket og avgasstrykket. Avgasstryk-kets måling er forbundet med visse van-skeligheter fordi ledningen til manometret lett og raskt tilsmusses ved forbrennlngs-rester, slik at det fåes uriktig målverdl eller at målingen er helt umulig. This invention relates to a device for measuring scavenge air and exhaust gas pressure in reciprocating internal combustion engines with charging, in particular in two-stroke engines with direct pressure coupling. While with uncharged engines the scavenge air pressure is a direct measure of the fouling of the inlet and outlet channels, particularly of a two-stroke engine's slits, the fouling with supercharged engines is measured by the pressure difference between the scavenge air pressure and the exhaust gas pressure. The measurement of the exhaust gas pressure is associated with certain difficulties because the line to the manometer easily and quickly becomes dirty with combustion residues, so that an incorrect target value is obtained or the measurement is completely impossible.

Hensikten med oppfinnelsen er å unn-gå den nevnte tilsmussing, og innretningen The purpose of the invention is to avoid the aforementioned soiling, and the device

i henhold til oppfinnelsen utmerker seg ved at måleledningen for spylelufttrykket over et strupeløp er forbundet med måie-ledningen for avgasstrykket. according to the invention is distinguished by the fact that the measuring line for the scavenging air pressure over a throttle is connected to the measuring line for the exhaust gas pressure.

Det har vist seg å være særlig hen-siktsmessig å utføre forbindelsen som en treveisventil som samtidig inneholder stru-peløpet, og hvor en ytterligere boring for utblåsing fra strupeløpet til atmosfæren er anordnet i treveisventilhuset. It has proven to be particularly expedient to design the connection as a three-way valve which also contains the throat, and where a further bore for blowing out from the throat to the atmosphere is arranged in the three-way valve housing.

Oppfinnelsen skal forklares nærmere The invention shall be explained in more detail

ved hjelp av et eksempel under henvisning til tegningen, hvor fig. 1 viser rent skje-mtaisk en motorsylinder med motgående stempler, som er utstyrt med måleinnretningen i henhold til oppfinnelsen. Fig. 2 a— 2e viser en treveisventil med strupestedet i forskjellige stillinger. by way of example with reference to the drawing, where fig. 1 shows purely schematically an engine cylinder with opposing pistons, which is equipped with the measuring device according to the invention. Fig. 2 a— 2e shows a three-way valve with the throat in different positions.

Ifølge fig. 1 er sylinderen 1 utstyrt med According to fig. 1, the cylinder 1 is equipped with

spyleluftsllsser 2 og avgasslisser 3 som åp- purge air slots 2 and exhaust gas slots 3 which open

nes og lukkes av stempler 4 henholdsvis 5. Med 6 er betegnet en spyleluftpumpe som over en ledning 8 tilføres luft fra en vifte 7 som suger inn luften i den med pilen nes and are closed by pistons 4 and 5 respectively. 6 denotes a flushing air pump which is supplied via a line 8 with air from a fan 7 which sucks the air into it with the arrow

viste retning. Viften 7 drives fra en avgass-turbin 9 som over en ledning 10 er forbundet med avgasslissene 3. Fra spyleluftslls-sene 2 fører en måleledning 11 til et strupested 12, mens en ledning 13 forbinder avgassiden med måleinnretningen. For måling av trykket er det anordnet et manometer 14 som ifølge eksemplet er utført som et kvikksølvmanometer som tillater en direkte avlesning av trykkdifferansen mellom strupestedets 12 begge silder og dermed shown direction. The fan 7 is driven from an exhaust gas turbine 9 which is connected via a line 10 to the exhaust ducts 3. From the purge air valves 2, a measuring line 11 leads to a throttle point 12, while a line 13 connects the exhaust side to the measuring device. For measuring the pressure, a manometer 14 is arranged which, according to the example, is designed as a mercury manometer which allows a direct reading of the pressure difference between both sides of the throat 12 and thus

differansen mellom spylelufttrykket og avgasstrykket. Formålet med strupestedet 12 er på den ene side å opprettholde en min-dre strømning av spyleluft gjennom ledningen, slik at ledningens 13 tilsmussing forsinkes eller forhindres og på den annen side å danne en strømnlngsmotetand for spyleluften som er så stor at den luftmeng-de som stadig strømmer gjennom ledningen 11 og 13 en minst mulig. Derved opp-nås at trykkfallet innenfor ledningen 11 som følge av strømningen blir så svakt at målingen av spylelufttrykket ikke blir uriktig. the difference between the purge air pressure and the exhaust gas pressure. The purpose of the throttle point 12 is, on the one hand, to maintain a smaller flow of flushing air through the line, so that fouling of the line 13 is delayed or prevented, and on the other hand, to form a flow countermeasure for the flushing air which is so large that the amount of air that continuously flows through lines 11 and 13 as little as possible. Thereby it is achieved that the pressure drop within the line 11 as a result of the flow becomes so weak that the measurement of the flushing air pressure does not become incorrect.

På fig. 2a—e er vist en treveisventil 15 1 et ventilhus 16 og ledninger 11 og 13 som munner ut i huset 16. Ventillegemet In fig. 2a—e shows a three-way valve 15 1 a valve housing 16 and lines 11 and 13 which open into the housing 16. The valve body

15 inneholder dessuten en boring 12 som virker som strupeløp. Manometeret 14 er i dette tilfelle bare antydet som et viserin-strument. Som manometer kan forøvrig anvendes vanlige kjente instrumenter som enten viser de absolutte trykk for spyleluft og avgass, eller, som vist i det første eksempel, bare måler den direkte trykkdiffe-ranse. Det er også mulig å anvende to manometre for målingen. 15 also contains a bore 12 which acts as a throat. In this case, the manometer 14 is only indicated as an indicator instrument. Conventional known instruments can also be used as manometers which either show the absolute pressures for purge air and exhaust gas, or, as shown in the first example, only measure the direct pressure difference. It is also possible to use two manometers for the measurement.

På fig. 2 a—b er vist treveisventilens 15 normale stilling under drift. En min-dre mengde luft strømmer stadig gjennom strupeløpet 12 og holder avgassledningen 13 fri for forurensninger. Ved ventilens 15 stilling ifølge fig. 2a viser manometret spylelufttrykket, mens ved stillingen ifølge fig. 2b måles det lavere avgasstrykk. Et kri-terium på avgasBledningens renhet fåes ved ventilens 15 stilling på fig. 2c og 2d. Hvis ledningen 13 er ren, vil et trykk inn-stille seg på manometret som ligger mellom spylelufttrykket og avgasstrykket, som begge er antydet med strekede visere på fig. 2c, og hvis avgassledningen 13 er til-stoppet, vil manometret vise spylelufttrykket, som på fig. 2d. I denne stilling danner ventillegemet 15 ingen stor strømnings-motstand, slik at en forholdsvis kraftigere luftstrøm blåser som følge av trykkfallet mellom ledningene 11 og 13 og fører foru-rensningene ut av 'den sistnevnte ledning. In fig. 2 a—b shows the normal position of the three-way valve 15 during operation. A smaller amount of air constantly flows through the throat 12 and keeps the exhaust line 13 free of contaminants. In the position of the valve 15 according to fig. 2a, the manometer shows the flushing air pressure, while in the position according to fig. 2b, the lower exhaust gas pressure is measured. A criterion for the cleanliness of the exhaust line is obtained by the position of the valve 15 in fig. 2c and 2d. If the line 13 is clean, a pressure will occur on the manometer which lies between the purge air pressure and the exhaust gas pressure, both of which are indicated by dashed pointers in fig. 2c, and if the exhaust line 13 is blocked, the manometer will show the purge air pressure, as in fig. 2d. In this position, the valve body 15 forms no great flow resistance, so that a relatively stronger air current blows as a result of the pressure drop between the lines 11 and 13 and carries the contaminants out of the latter line.

På fig. 2e er ventilen 15 vist i den stilling som tillater utblåsing av strupeløpet 12 i det frie. For dette formål er ventilhuset 16 utstyrt med en boring 17. Da trykkfallet fra spyleluften til atmosfæren er vesentlig større enn fra spyleluften til avgassen, kan strupeløpet 12 renses på en enkel og rask måte. In fig. 2e, the valve 15 is shown in the position which allows blowing out of the throat 12 in the open air. For this purpose, the valve housing 16 is equipped with a bore 17. As the pressure drop from the scavenging air to the atmosphere is significantly greater than from the scavenging air to the exhaust gas, the throat 12 can be cleaned in a simple and quick way.

Anordningen i henhold til oppfinnelsen kan lignende måte også brukes i for-bindelse med firetaktmotorer. The device according to the invention can similarly be used in connection with four-stroke engines.
