| Abstract: | In order to improve the fuel economy, dynamics and clean emission of automotives, the air-fuel ratio of mixture gas in electronic-controlled fuel injection systems of engines must be controlled strictly .So it is necessary to measure the air flow. A Karman-type vortex air flow meter is introduced in this paper, which has many advantages of small intake resistance, small volume, light weight, fast response, low pressure loss, high pulsating- flow measuring precision, wide measuring range and so on. |
