问：加速时，我的汽车在加速时发出高音高的声音。2010 Subaru Impreza

嗨 - 您的Impreza配备了涡轮增压发动机，可增强性能。这为发动机产生加压空气，增加了功率。为了避免发动机过度压力，有增强压力控制和“垃圾门" port to vent over-pressure - all electronically controlled. This can produce "chirping-like" noises under acceleration, especially during and after gear changes for manual transmission cars. This is normal behavior, and shouldn’t cause concern. If it seems excessively loud, I would recommend an发动机检查通过移动，专业的机械师，例如来自Mymechanic的一名机械师，他们将来到您的位置，诊断此问题，使您对损万博体育入口害的准确评估和维修成本估算。
