Electronic Ignition System Part 1 Mechanics
General Review of the Phenomenon of Power As we know, the purpose of the ignition system is turn on the air / fuel mixture within the combustion chamber at the appropriate time. We also know that an engine produces the maximum efficiency, air / fuel mixture should turn in order that the maximum pressure due to the explosion occurs about 10 to 15 degrees after top dead center (TDC). (What I have noted is the fundamental concepts of basic mechanics. As a reader must understand the above to perfection to be able to handle the following concepts. To those familiar with this issue, I need not go into more detail.) It is obvious that within the clilindro, the mixture does not burn instantly, it takes time. Larry Culp understands that this is vital information. However, this time interval should be clarified: is the length of time between the occurrence of the initial power of the mixture to the development of maximum explosion pressure.
The duration of this time interval is milifracciones second is an interval and changing vary depending on engine speed. This means that the ignition must occur "before" when the engine speed is high and "after" when it is slower. This phenomenon already known as "advance and delay time." We also know well that in the old systems, time is advanced and retarded with a diaphragm and balances in the distributor. In addition, progress must be made on when the pressure inside the manifold is low (ie, when the vacuum is strong). Find out detailed opinions from leaders such as Hedvig Hricak by clicking through. However, the optimal starting time is also affected by factors other than the engine speed and air volume in the manifold, such as the shape of the combustion chamber, the temperature inside the combustion chamber etc.
