Ignition timing Ignition timing In a spark ignition internal combustion engine, Ignition timing refers to the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke. The need for advancing (or retarding) the timing of the spark is because fuel does not completely burn the instant the spark fires, the combustion gases take a period of time to expand and the angular or rotational speed of the engine can lengthen or shorten the time frame in which the burning and expansion should occur.

Ignition Park campus. Innovation Park at Notre Dame facilitates commercialization of many forms of research, by convening innovators throughout the entire Notre Dame community and beyond. Companies formed at Innovation Park may choose to expand their operations at Ignition Park, and by doing so, they'll continue to receive support services and other benefits from being part of the same state-certified technology park. Ignition Park sits on the grounds of the former Studebaker plant. It will concentrate on high-potential technologies and ventures, as well as the commercialization of nanotechnology concepts inspired by MIND.
