| 摘 要： | 长江750的进气噪声主要由250 Hz以下低频和1 000 Hz以上高频组成,并随转速的增加而急剧增大,转速每增加1倍,噪声增加10 dB(A)以上;但它受负荷的影响不大,随负荷的增加稍有增加。采用整体密封复合式消声空滤器加装辅助进气管等措施,不仅达到良好的降噪效果,还可减少进气阻力,确保滤清效率和储尘能力。

| Abstract: | The intake noise of Changjiang 750 motorcycle, which is composed of low frequency below 210 Hz and high frequency above 1000 Hz, will sharply intensify with the increase of the engine speed, that is, when the engine speed lifts by 100%, the noise will intensify by more than 10 dB(A). But the noise is rarely affected by load increase. An integral sealed combination air filter is added to the supplementary intake pipe for the sake of reducing noise and intake resistance, and ensuring filtability and dirt-holding capacity. |
