Development of calorimetric motor fuel flowmeter with increased metering accuracy by adjusting the inlet temperature
In the paper, the emphasis is made on the diversity of motor- transport operation conditions and factors which should be consid- ered while developing modern motor fuel flowmeters. It is shown that calorimetric flowmeters correspond to the motor transport operating conditions, fuel flow metering standards and can be recom- mended for their usage in the process of automobiles exploitation. They also can be useful for the bio-fuel flow metering.A concept of a new calorimetric motor fuel (bio-fuel) flowme- ter with adjusting the inlet temperature was developed for the car engines, having up to date supply systems (the systems of reverse fuel decanting into the tank (through recoil lines)), which allows to increase the accuracy of motor fuel flow metering.Field researches of brassboard at the automobile have shown the decrease (compared to the prototype of flowmeter) in the relative ac- curacy of diesel oil flow by 7-13 % depending on the engine behavior.
