摘　　要：水冷摩托车与风冷摩托车相比,冷却能力强,能保证发动机始终在最佳温度状态下工作;水冷发动机精心设计的冷却液隔层(水套)还可最大限度地吸收、隔绝活塞的运动噪声、燃烧噪声及气门的落座噪声等,从而起到大幅度降噪的作用,但就此也不能认为水冷机就是零噪声。Compared with motorcycle air-cooled engine, water-cooled engine which is strong in cooling capacity can keep the engine work at the optimum temperature. The well-designed water jacket is capable of absorbing and isolating the motion noise of the piston, combustion noise and the noise caused when the valve returns, so that it plays a big role in reducing noise greatly, but it can not be said that watercooled engine is of zero noise.

关 键 词：水冷发动机 噪声 控制技术
