4 , Structure introduction
Due to the spark plug and the engine between the relationship between the ever-changing engine technology is bound to promote the spark plug of continuous innovation.
Spark plug through the history of development and progress, you can see the evolution of spark plug structure and change.
1, standard and prominent spark plugs
The standard spark plug is a single side electrode spark plug that is slightly lower than the end of the housing thread. It uses the most widely used conventional ignition end structure for side-mounted valve engines. In order to distinguish it from the later "prominent type", this structure is called "standard type".
The protruding spark plug was originally designed for overhead valve engines, and its insulator skirt protrudes into the combustion chamber. In the combustion of the mixture to absorb more heat, idle at a higher working temperature, to avoid fouling; high-speed valve due to the top of the inhaled air flow at the insulator skirt, cooling it, so that the maximum temperature increase , So the heat range is larger. High-grade spark plug is not suitable for side-mounted valve-type engine, because of its inlet and turn more air flow on the insulation of the skirt is not much.
Spark plug
From the ignition effect, the spark should be the best place to flow in the mixture. The engine combustion chamber requires a different optimum ignition location for different structural designs. The ignition position can be understood as the position of the spark gap in the combustion chamber, that is, the distance from the end of the spark electrode center electrode to the end of the housing.
Ordinary protruding spark plug ignition position of 3mm, off-road racing and large displacement motorcycle use of "super-prominent" spark plug, ignition position up to 7 ~ 10mm. Ignition near the center of the combustion chamber, the flame propagation distance is shortened, which will shorten the combustion cycle and reduce the magnitude of pressure changes, is conducive to improving the engine power.
