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 ...

According to NGK, adding 10 degrees of ignition timing at idle will raise the spark plug temperature anywhere from 180- to 210 degrees Fahrenheit. This means that adding just one degree of ignition ...

Duvernay has the highest stock output production Quad 4: the 190-hp 1991 to 1992 RPO W41. The 1993 W41 lost 10 hp due to smaller exhaust ports. Photo: Kevin Davis via Wikipedia (CC-3.0) A 1992 ...

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 ...

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, ...

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, ...

Porsche has been working on a new way to help you keep your catalytic converter alive and well, using the age-old method of exhaust gas recirculation (EGR) alongwith modified ignition timing for a ...

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 ...

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...
