The process of setting the time that a spark will occur in the engine [[combustion chamber]] (during the [[power stroke]]) relative to [[piston]] position or [[crankshaft]] rotation. Setting the correct ignition timing is crucial in the performance of an engine. The ignition timing affects many variables including engine longevity, fuel economy, and engine power. Modern engines that are controlled by an [[engine control unit]] use a computer to control the timing throughout the engine’s RPM range. Older engines that use mechanical spark [[distributor]]s rely on inertia (by using rotating weights and springs) and manifold vacuum in order to set the ignition timing throughout the engine’s [[RPM ~~range~~]].
