Designing and manufacturing thermal mass flow meters for biogas engines

Abstract

The use of Biogas fuel for internal combustion engine is an issue of great interest to scientists. To increase the efficiency of biogas engines,we need to manufacture the kit which has better features. This article shows that the use of thermal mass flow meters for biogas engines and flow meter calibration method. A system of measuring equivalence ratio  of biogas diesel dual fuel engine is established by 2 hot wire sensors of the automobile. The relationship between real  given by gas analysis in downstream of mixer and ratio of output voltage of the two sensors allows us to determine calibrated coefficient of the system. The research result can be used to measure the flow of biogas for the engines used in experiments.
