Specifiion

Description

The role of the crankshaft position sensor is to determine the position of the crankshaft, that is, the angle of rotation of the crankshaft and the speed of the engine. It usually works with the camshaft position sensor - to determine the basic ignition timing. We all know that the engine starts to ignite at the end of the compression stroke, so how does the engine computer know which cylinder should ignite? It is calculated by the signals of the crankshaft position sensor and the camshaft position sensor. Through the crankshaft position sensor, you can know which cylinder piston is at the top dead center, and 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. The crankshaft position sensor is usually installed at the front end of the crankshaft (at the pulley) near the large flywheel or in the middle of the crankshaft at the rear end of the crankshaft. Early models were also installed in the distributor, which is one of the most important sensors in the control system. Its functions are: to detect the engine speed, so it is also called a speed sensor; to detect the top dead center position of the piston, so it is also called a top dead center sensor, including detecting the top dead center signal of each cylinder used to control ignition, and used to control sequential injection. TDC signal for the first cylinder of oil.
