Two wheeler 4-stroke small Engine with Kick Start requires longer spark duration along with better spark energy in order to burn the lean mixture and to have better Start ability, lower trigger start RPM is also important to enable ease of start. An effective Ignition System needs to be designed for the above purpose. Hence Transistor Controlled Ignition/Inductive Discharge System (TCI/IDI) unit is preferred which gives all the above mentioned requirements. Normally any conventional TCI/IDI operated 4-stroke two wheelers will have D.C power line align with a Power Source for its operation. The 2 Wheeler Kick start version cannot afford the DC Power Source due to Cost, Hence the Electrical System will not have the DC Power Line. So it is not possible to operate a Conventional TCI/IDI system as it is DC Power based System. The challenge is to operate the TCI/IDI ignition unit without DC Power Source i.e. using AC Source.
