section::::the basic principle.:types.









































most cdi modules are generally of two types:









































bullet::::- ac-cdi









































the ac-cdi module obtains its electricity source solely from the alternating current produced by the alternator. the ac-cdi system is the most basic cdi system which is widely used in small engines.









































note that not all small engine ignition systems are cdi. some engines like older briggs and stratton use magneto ignition. the entire ignition system, coil and points, are under the magnetized flywheel.

the cellular approximation theorem can be used to immediately calculate some homotopy groups. in particular, if formula_7, then formula_8: give formula_9 and formula_10 their canonical cw-structure, with one 0-cell each, and with one "n"-cell for formula_9 and one "k"-cell for formula_10. any base-point preserving map "f":formula_9→formula_10 is by the cellular approximation theorem homotopic to a constant map, whence formula_8.
