3 大众/奥迪车系可变气门正时技术在大众/奥迪车系上也广泛采用了可变气门正时系统(图22)。该系统具有特别的设计,其传动方式及进、排气凸轮轴的分布如图23所示:排气凸轮轴安装在外侧,进气凸轮轴安装在内侧,曲轴通过齿形带首先驱动排气凸轮轴,排气凸轮轴通过链条驱动进气凸轮轴。如 3 VW / Audi Vehicle Variable Valve Timing Technology Variable valve timing systems are also widely used in Volkswagen / Audi vehicles (Figure 22). The system has a special design, the transmission and intake and exhaust camshaft distribution shown in Figure 23: Exhaust camshaft mounted on the outside, the intake camshaft mounted on the inside, the crankshaft through the toothed belt first driven exhaust Camshaft, exhaust camshaft through the chain to drive the intake camshaft.
