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

Older vehicles with distributor-based ignition systems need their timing checked on a regular basis, otherwise you can have a host of problems. Starting becomes difficult, idling will be rough, ...

So you're wondering what's the big deal with "digital," are you? Unless you've been hiding under a rock for the past decade, almost everything you hear about is new, improved, and digital. The "old ...

Taking into account all the products needed to build a high-performance powerplant, an ignition system is probably last on the list. Yet the ignition system is probably one of the most important ...

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 ...

The automotive ignition system is an incredibly amazing machine that has evolved for more than 100 years already and continues to evolve as the demand drives the need to develop more efficient engines ...

“Runs good!” You’ve seen that a lot of times looking at Craigslist ads for cars and motorcycles, especially older ones. But what does that even mean? Why wouldn’t it “run good,” anyways Shouldn’t ...
