当选取的谐振回路器件满足振荡器起振条件时振荡器开始工作，VCO内的有源器件等效构成的负电阻部分所提供的能量能够满足谐振回路所消耗的能量则振荡电路的振荡条件能够得以维持，VCO能够正常工作。然而，VCO实际的工作状态绝非理想状态，并不是设计时所假定的终端连接理想的50欧姆负载，因此其终端负载条件的变化会导致VCO出现输出振荡频率发生变化的非线性现象，这就是频率牵引，其表征参数为频率牵引系数。从可以看出，从VCO输出看去的阻抗变化会引起VCO的有源器件结上直流电压的变化，也就是说，VCO输出反射回来的信号功率能引起晶体管漏电流和偏置点的波动，导致该双极型晶体管集电极与基极之间的电压（Vcb）发生变化，影响集电极与基极之间的电容（Ccb），从而通过影响整个回路的谐振状态和条件导致振荡频率和相位噪声的改变。

因此在轿车和载货汽车上迅速推广使用。汽油机电控喷射供油系统是电动燃油泵把燃油从油箱中泵出，经滤清器过滤后由配油管送至喷嘴。由于油泵在一定转速下运转，因此输出的油量不变，当油路内压力升高时，压力调节器开始工作，此时减压阀打开，多余的燃油经回油管返回油箱，从而保持送给喷嘴的燃油压力恒定不变。由于供油系统的油压一定，所以喷油器喷出的燃油量与喷油器开启的时间成正比，因此可以通过控制喷油器的开启时间来控制系统的供油量。

低压接头用手上紧，加上锁紧螺丝可减少以上故障的发生，一旦发现低压接头损坏，应重新更换。高压接头的故障与低压接头差不多，污染和装置不当也常有发生。使用合适的工具在拧紧接头的时候一定要仔细，过紧可能会损坏螺纹、刃环等，引起漏液，*糟糕的是会使接头断在螺母内部。使用手拧紧接头，不需要任何工具就可以密封。旋紧接头时要用死扳手，不用活扳手，保证不损坏接头。注意接头的清洁组装与拆卸接头时要检查在密封面上有无微粒和无机盐晶体。
