Abstract

Trykkføleren (10) ifølge oppfinnelsen, særlig beregnet til overvåking av anordninger på forbrenningsmotorer, har som formål kontinuerlig å sikre optimal omdanning av drivstoff til effekt under de mest mulig pålitelige driftsforhold på lang sikt. Ideelle overvåkingsparametre for dette formål er måling av forbrenningstrykket i hver sylinder og av innsprøytingstrykket for det væske- eller gassformige drivstoff. For dette formål er det foreslått en ny trykkføler (10), heretter betegnet en C-formet føler. Den eren skive (12) med en trykkmåleboring (13) for målemediet og en i en vinkel på 90° i forhold til denne utfor-met strekkmåleboring (14) for måleelementet, og et sekantsnitt (17) som danner c-formen.Avhengig av utformingen kan den C-formede trykkføler (10) ifølge oppfinnelsen brukes til varme forbrenningsgasser og til drivstoff og andre væske- eller gassformige substanser. Ved anvendelse til overvåking av forbrenningsmotorer, fremtrer svært spesielle fortrinn ved å montere den C-formede trykkføler (10) mellom forbrenningskammeret og indikatorventilen (15) i stedet for etter indikatorventilen (15), hvilket muliggjør periodisk gjennomblåsing og følgelig fjerning av alle forbrenningsrester. Dessuten kan det til enhver tid utføres en kalibreringsmåling uten noen forstyrrel-se av driften. Følgelig muliggjør idéen med den C-formede føler for første gang en pålitelig måle-overvåkingsanordning for forbrenningsmotorer, som til enhver tid kan verifiseres. uten å forstyrre driften.The pressure sensor (10) according to the invention, in particular intended for monitoring devices on internal combustion engines, has the purpose of continuously ensuring optimal conversion of fuel to power under the most reliable operating conditions in the long term. Ideal monitoring parameters for this purpose are the measurement of the combustion pressure in each cylinder and of the injection pressure of the liquid or gaseous fuel. For this purpose, a new pressure sensor (10) has been proposed, hereinafter referred to as a C-shaped sensor. It is a disc (12) with a pressure measuring bore (13) for the measuring medium and one at an angle of 90 ° relative to it formed a tensile measuring bore (14) for the measuring element, and a secant section (17) forming the c-shape. According to the design, the C-shaped pressure sensor (10) according to the invention can be used for hot combustion gases and for fuel and other liquid or gaseous substances. When used for monitoring internal combustion engines, very special advantages appear by mounting the C-shaped pressure sensor (10) between the combustion chamber and the indicator valve (15) instead of after the indicator valve (15), which enables periodic blowing and consequent removal of all combustion residues. In addition, a calibration measurement can be performed at any time without any disturbance to the operation. Consequently, the idea of the C-shaped sensor enables, for the first time, a reliable measuring-monitoring device for internal combustion engines, which can be verified at any time. without disturbing the operation.
