Abstract:
1. A scavenging line/sensor assembly comprising: a scavenging line leading from a hydrocarbon accumulator to a combustion engine; a sensor configured to measure a hydrocarbon content in a gas stream in said scavenging line, said sensor comprising: at least one heating element configured to heat the gas stream; and at least one temperature probe configured to determine a temperature of the heated gas stream comprising: wherein the measured hydrocarbon content in the gas stream is based on the determined temperature differences, wherein each of the first and the second temperature probes comprises two temperature probes, wherein the first temperature probe determines a first temperature difference upstream of the heating element in the gas stream; and the second temperature probe determines a second temperature difference arranged downstream of the heating element in the gas stream, whereby a temperature difference between the first and second temperature differences corresponds to a thermal capacity of the gas stream and a temperature sum of the first and second temperature differences corresponds to a corresponds to a thermal conductivity of the gas stream.
