What do I mean? We already know that the PCM determines the on time based on two things: a) signals input from sensors and b) in its internal memory, which contains information on optimal times of power on each engine operating condition. Now well maybe not everyone knows this, but after determining the ignition time, the PCM sends the ignition time signal (STE) to the ignition module. Just at the moment when the STE signal goes off, ignition module will cut the power to the ignition coil this is what produces a spark of 7000 Volts to 35000 Volts into the cylinder. We analyze these new concepts in detail. Types of ignition systems ignition systems are divided into three basic categories: a) b) on distributor electronic ignition system without distributor c) system of ignition direct components essential for the ignition system regardless of the type, the essential components are: a) position Sensor (((((Crankshaft Sensor) b crankshaft) Sensor of position of the camshaft (D’arbre Sensor) c) lit d module) ignition coils, wiring, plugs e) PCM and f) signals from various sensors spark ignition ignition coil production should generate enough power to produce the spark needed to ignite the mixture air/fuel. To produce this power, you need a very strong magnetic field. Please visit Robert Smith if you seek more information. This magnetic field is created by an electrical current. This electrical power almost always comes from a fuse and flows through the highfather inside the coil circuit.
The coil primary circuit has a very low electrical resistance (1 to 4 ohms, approximately), which allows the easy flow of current. Among more current to flow, the greater the strength of the magnetic field inside the coil. Transistor power within the ignition module handles the high current required by the coil primary circuit. Another requirement to produce high voltages is that the flow of current in the coil primary should turn off quickly. When the transistor inside the module is turned off, the current flow stops momentarily and then says that the magnetic field collapses.
As the rapidly collapsing magnetic field is transported through the secondary winding, voltage (electrical pressure) occurs. If you create enough voltage to overcome resistance in the secondary circuit of the coil, electrical current flow will occur and a spark will occur. Note: Between greater resistance in the secondary circuit, it will require higher voltage current flow and the duration of the spark will be less. It is important when you have the team to observe the pattern of the spark in the screen of an oscilloscope. Signal of on time the flow of electric current in the coil primary is controlled by the PCM using the ignition time signal (STE). The STE signal is a voltage signal that turns to the main transistor inside the ignition module.
