This Malaysian Standard specifies the methods and test conditions for testing battery-supplied ignition systems for spark-ignited internal combustion engines.
Because of the difficulties in producing repeatable measurements with atmospheric spark gaps and dif- ferent observers, two methods of obtaining the re- sults necessary for calculating the System output energy are gjven.
Method A
- using spark gaps for the energy measurement (test arrangement A). The output energy obtained by this method is called spark energy, Esp.
Method B
- using a Zener diode string for the en- ergy measurement (test arrangement B). The output energy obtained by this method is called Zener discharge energy, Ezd. This method is not suitable for Systems giving alter- nating spark current.
Method B is also recommended for the comparative testing of ignition coils and current interruption sys- tems.
