Essentially, a multi-cylinder engine is a collection of individualengines operating at different combustion and mechanical efficiencies.If we can optimize the power output from each one, the overall ...

Welcome back for Part 2 of tune-up tips for your older Corvette. Last time we talked about tricks of the trade when setting points. This month we will talk about setting ignition timing. The most ...

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 ...

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, ...

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 ...

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 ...
