Description

The role of the crankshaft position sensor is to determine the position of the crankshaft, that is, the Angle of the crankshaft and the engine speed. It usually works with a camshaft position sensor to determine the basic ignition time. We all know that the engine starts firing at the end of the compression stroke, so how does the engine computer know which cylinder to fire? It is calculated by the signal of the crankshaft position sensor and the camshaft position sensor, through the crankshaft position sensor, you can know which cylinder piston is at TDC, through the camshaft position sensor, you can know which cylinder piston is in the compression stroke. This way, the engine computer knows when to fire which cylinder.
