Electronic fuel injection system

Posted: 03 Jun 2011 08:34 PM PDT

Hi CEngz,
Facing a new challenge in making "Electronic Fuel Injection System". We are developing a circuit such that it generates a square wave form signal (12V peak to peak). This output signal is fed to MOSFET/Solid State Relays to drive the injector operating at high current (20A) & High voltage (24V) from 2 car batteries connected in series. Can anyone suggest a part/item along with the connections. Any help would be appreciated.
Thank You.
