PT燃油系统的特点(1)PT燃油系统的优点1)喷油正时由配气凸轮轴决定,安装PT泵时无需调整喷油正时。2)PT燃油系统结构紧凑,整个系统中只有喷油器中有一副精密偶件,精密偶件数较采用柱塞式喷油泵的燃油系统大为减少。3)由于高压只在喷油器中产生,PT泵以较低的压力工作运行(出口压力约为0.8~1.2MPa)。没有高压油管也没有高压接头,消除了压力波动的问题。它可以采用很高的喷油压力,燃油雾化质量好,而且也不存在高压漏油的问题。4)由于PT燃油系统是利用油压调节的,在油泵磨损时,具有自动补偿的能力,供油量不会下降,不用重新调整。5)有相当数量的燃油(约80%)经过喷油器回流,可对喷油器进行冷却和润滑,并把可能存在于油路中的气泡带走。回流的燃油带着喷油器的热量直接流网浮子油箱,在冬季,还可以起到加热油箱中燃油的作用。6)喷油器可单独更换,因此不必像柱塞泵那样需在试验台上进行供油均匀性的调整。(2)PT燃油系统存在的缺点1)NH、N及K系列机上采用的PT泵,由于除了PTG调速器外还装有MVS调速器,增压机型还装有AFC控制器,故结构上仍比较复杂。2)PT燃油系统的喷油器由于采用转矩调整法调整,如调整不当时可能引起燃油雾化不良,排气严重冒黑烟和功率下降,有时甚至可能将喷嘴压坏,导致喷油器油嘴脱落。3)PT泵需在专用的PT燃油泵试验台上进行安装调试,使用中仍感不便。
