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 ...

The timing chain is the heartbeat of your engine, keeping pistons and valves in perfect sync. When it wears or stretches, performance drops and repair bills soar. Knowing the warning signs, using the ...

We must first understand what each of these two systems does for a car. They both serve the same purpose, which is to coordinate the movement of the crankshaft as well as the camshaft(s) so that the ...

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 ...

From carburetor care to advanced EFI mapping, mastering engine tuning is about balancing airflow, fuel, and timing for peak performance. Whether you’re chasing horsepower with forced induction or ...

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 ...
