		<title>Ignition Spark Energy</title>
		<description><![CDATA[Ignition fundamentals. we get into how the fire gets started . . . and different ways to initiate all the pyrotechnics
We&#8217;ve deliberately omitted discussion of the ignition process and the means by which it can be accomplished. Our reason was that it might be better to delay discussion on what happens both up and downstream [...]]]></description>

		<title>Spark Timing</title>
		<description><![CDATA[ Now, in a single-spark ignition engine (one per cylinder), the combustion flame begun at the spark plug travels comparatively slowly away from the plug. As the flame moves throughout the combustion space, heat released by the burning fuel causes burned gas expansion. This tends to increase the velocity of fame travel. Spark timing, therefore, [...]]]></description>

		<title>Ignition Voltage</title>
		<description><![CDATA[And in accordance with the engine&#8217;s particular firing order, we&#8217;re now back to the combustion process. But for purposes of a clearer understanding of how this combustion spark was developed, let&#8217;s return to the engine&#8217;s battery and see what takes place from wet cell to &#8220;fire.&#8221;
In spark ignition engines, there are two basic methods by [...]]]></description>

		<title>Distributor</title>
		<description><![CDATA[Next comes the ignition distributor, the ignition points it houses, a capacitor and some sort of timing advance mechanism (one mechanical and one, usually, governed by intake manifold vacuum). We&#8217;ve already mentioned that a distributor&#8217;s ignition points serve as an electrical &#8220;switch&#8221; for the interruption of current (voltage) flow through the ignition points. Such points [...]]]></description>

		<title>High Engine RPM</title>
		<description><![CDATA[As engine speed increases to a maximum, less combustion time is available, volumetric efficiency (cylinder filling efficiency) is reduced, so less fuel and air are available for combustion, flame travel is slower, and ignition timing needs to be advanced. And if you&#8217;ve heard of devices that retard timing at high engine rpm, then there was [...]]]></description>
