北京 BJ1040、BJ2020型、天津 TJ1040型等轻型汽车,一旦发生加速困难时,往往会出现汽车加速时消声器“放炮”,发动机中速或高速运转时化油器回火,有时消声器还出现“突突突”的连续响声,汽车行驶无力。实践表明,配置 H201双腔分动式化油器的轻型汽车,产生加速困难的原因主要有:加速泵皮碗磨损、翻边或卡住,加速泵回油阀、三角针阀卡住或加速泵柱塞脱落,加速泵喷嘴或油 Beijing BJ1040, BJ2020 type, Tianjin TJ1040 type and other light vehicles, in the event of acceleration difficulties, there will often be car acceleration muffler “shot”, the engine speed or high speed carburetor tempering, muffler sometimes appear "sudden process Continuous noise, the car driving weakness. Practice shows that, equipped with H201 dual chamber split carburetor light vehicles, resulting in acceleration difficulties are: accelerated pump bowl wear, flanging or stuck, accelerated pump return valve, triangular needle stuck or accelerated Pump plug off, accelerate pump nozzle or oil
