简易汽车油耗计设计研究

Design and Research of Simple Fuel Wastage Meter for Automobile

根据汽车发动机排量和转速推算出排气管里废气体积流量和流速,用动压测定管测量排气管里气体的全压和静压,在已知发动机空气流量或空燃比、过量空气系数的情况下,利用有关公式,可得出发动机单位时间燃油消耗量。

According to engine displacement per cycle and running velocity, exhaust volume discharge and flow velocity are calculated out. The whole pressure and back pressure in exhaust pipe have been measured by flow pressure pipe, If air mass discharge or A/F and a for engine is known, the engine fuel consumption per second can be obtained by use of concemed formulas.
