Retarding the spark to TDC or later makes the engine run smooth, but with lots less power. The idea is to get thefuel/air mixture to ignite and start to burn, and thus build up pressure just before the piston reaches TDC, and complete the combustion before it gets to the end of the power stroke. You do not want any un-burned fuel left as the exhaust stroke begins. Typically, spark ignition begins anywhere from 6 to 26 degrees BTDC. One of the reasons that Diesels don't have the initial "zip" of a gasser is that the fuel won't ignite until the compressed air temp gets high enough, which is a lot closer to TDC. And the CDI engines get the full fuel burn and low emissions because they use 4-5 pulses of very small spurts of fuel (some in fractions of microseconds), first to start the burn, then to make some power, keep it going, and burn all residuals - something mechanical IPs could never accomplish.
