The camshaft rotates in phase with the crankshaft, but at half its speed.

凸和曲协调旋转, 但是曲的一半。

The main products are as follows, exhaust manifold, bent axle, camshaft, rubbing sassafras nestification, gearbox, support, flywheel, etc.

排气歧管、曲、凸、摩擦嵌套、变箱、支、等。

In case that the camshaft signal measured by the first falling edge after dentation is low, then the following TDC would be of the first cylinder.

若缺齿后第一个下降沿检测到凸信号为低，则接下来的TDC是一缸TDC。
