Content
In the present investigation, the main aim was to apply the frequency parameter for viscous flow air meters to the measurement of air consumption of gasoline engines at full- and part-throttle conditions. In the previous investigation, it was verified only for a single-cylinder, 4-stroke engine without a carburetor.
Experiments have shown that at higher engine speeds, the linear relationship between the rate of flow and the pressure difference deviates. Thus, the frequency parameter obtained at deviation speeds for each viscous flow meter can be used as a criterion for the dependable working range.
As a result, an exponential relationship has been found between the frequency parameter and the plate distance of the viscous flow air meter. According to this relationship, it is clear that the dependable working range of the viscous flow meters increases when applied to the engine running in part-throttle condition.
