The Advance CurveAll engines require an ignition curve based both on the requirements of engine rpm and cylinder filling (volumetric efficiency). This means that at 3,000 rpm with the throttle open ...

What's An Advance Curve?In the basic design of an internal combustion gasoline engine, an air/fuel mixture burns in the combustion chambers to force the pistons down, which in turn, spins the ...

Ignition timing is like seasoning: some is good, but too much ruins the results. Bumping up the ignition timing on pushrod 5.0s is a time-honored trick to wake up the under-hood lump. The EFI system ...

Every engine has a means of coordinating the timing between the valve train and the rest of the engine. Some engines use a timing chain and some a timing belt. A timing belt has the relatively ...

What Does the Timing Belt or Timing Chain Do? On a conventional piston engine — which is found in virtually all modern passenger cars — the up-and-down motion of the pistons turn the crankshaft, and ...
