Camshaft Sensor for Astra G/J X18XE1 and X20XEV Engines - Simtec 70 Fuel Injection System
|
Camshaft Sensor, X 18 XE1 and X 20 XEV The camshaft sensor (Hall sensor) is used to detect the camshaft position and provides the cylinder recognition required for sequential injection. Two offset segments are attached to the exhaust camshaft pulley. The camshaft sensor consists of two Hall elements, with one element allocated to each segment. The camshaft sensor is therefore capable of recognising the camshaft position as soon as the ignition is "ON", i.e. before the engine is started. The quick start system allows the exact fuel quantity to be allocated to each cylinder right from the first engine revolution. If the crankshaft pulse pick-up malfunctions, a camshaft emergency program is available. The segments are located on the front of the exhaust camshaft pulley in the X 18 XE1 (illustration G 5083) and on the rear in the X 20 XEV.
