Ignition systems with dealer signals of speed of movement of motor and position of the Pistons come crankshaft position Sensor and the Sensor’s position of camshaft, respectively. The second in the majority of cases is located in the Distributor or the motor head. At the appropriate time during the compression in the cylinder, the PCM sends a signal called STE into the ignition module. This in turn activates transistor inside the module, which sends electrical current through the primary winding of the ignition coil. At the optimum moment for ignition to occur, the PCM will disable the STE signal and there, transistor turn off the flow of current through the primary winding. The created magnetic field will collapse, will induce an instantaneous high voltage that will download the induced electric current, this will travel through the cable secondary coil and there by the coil wire, then to the Distributor CAP, immediately to the rotor, and from there to the terminal to where the rotor points it will continue by the high voltage cable, it will reach to the spark plug, will burn fuel and finally, play ground.
The rotor position determines the cylinder that receives the spark. Firing order firing order will find in guides and manuals of the manufacturer. Although there are exceptions, the vast majority of manufacturers identify cylinders in the following manner: to) the numbering of cylinders in V-8 engines, odd cylinders are numbered cylinders on the right bank and the left bank. (b) the numbering of cylinders in a V-6 engine, odd cylinders are numbered cylinders on the right bank and the left bank. (c) 6 cylinder in-line engines are numbered consecutively from 1 to 6, with 1 on the front cylinder. (d) 4-cylinder engines are numbered front to back consecutivamentre. In many cases, distributor caps or the intake manifolds are recorded the firing order.
