  4. Auto reignition - Wikipedia

    en.wikipedia.org/wiki/Auto_reignition

    Auto reignition lowers the risk of gas leaks: if a flame goes out during operation, for example, from vibration or a gust of wind; due to misoperation—a user might not understand the "light" position must be maintained for about 0.5 to 2 seconds before turning the burner knob on fully.

    en.wikipedia.org/wiki/Ignition_system

    The most famous aftermarket electronic ignition which debuted in 1965, was the Delta Mark 10 capacitive discharge ignition, which was sold assembled or as a kit. The Fiat Dino was the first production car to come standard with EI in 1968, followed by the Jaguar XJ Series 1 [9] in 1971, Chrysler (after a 1971 trial) in 1973 and by Ford and GM in ...

    Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is 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.
