Ignition timing is easily the single most important tuning adjustment on an internal-combustion engine, yet the concept of ignition curves continues to be elusive for many enthusiasts. All it takes to ...

Having a car with outrageous low-end throttle response and top-end horsepower is something every gearhead strives for. The correct combination of parts will get you close, but it’s the tune-up that ...

There's a tiny silver can on the side of most distributors that is easily the most misunderstood component of any distributor-based ignition system. Feared by many, and ignored by many more, the ...

underway before tdc is reached. This gives a maximum cylinder pressure (and work output). This ignition timingcondition is about 20 degrees of crank rotation before tdc, i.e. 20 degrees btdc. From, ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...

Like much in life, the difference between detonation and pre-ignition, and their effects, comes down to timing. Both refer to a situation when an engine's fuel/air mixture combusts at the wrong time, ...
