Web1 mrt. 2024 · Ignition timing is measured in degrees of a crankshaft rotation before top dead center (BDTC). Spark plugs need to fire at the right time, which can be achieved by advancing or retarding the timing of the engine. Timing advance means that the spark plugs are firing earlier in the compression stroke, farther from TDC. WebUntitled - Free download as PDF File (.pdf), Text File (.txt) or read online for free.
