Just as the piston hits top dead center (TDC), pressure is maximized.Pressure is built in the cylinder as the burning gases expand.The air/fuel mixture in the combustion chamber is ignited.The spark plug fires during the compression stroke.If the spark plug fires too soon or too late during the compression stroke, damage to the engine can occur over time.ĭuring the process, the following steps occur: Ignition timing is an important process when it comes to running an engine. If you’re interested to find out more about ignition timing, how it works, and how you can modify it to affect the performance of a vehicle, then keep on reading. Performance is through advancing or retarding ignition timing. Considering this, it makes sense that there would be ways to affect the ignition timing process to increase vehicle performance. Ignition timing is an important process that plays a big role in the performance of an engine. Ignition timing controls when the spark plug fires during this process. A car’s ignition timing comes into play during the compression stroke. There are four steps involved: intake, compression, power and exhaust. From the crankshaft and camshaft to the pistons, rods, and pulleys, all of these components are moving quickly and at specific times so things function properly.ĭuring this process, your car’s engine utilizes four distinct piston strokes in order There are a lot of moving parts in a car’s engine.
