A type of electronic fuel injection system that uses a single injector or pair of injectors mounted in a centrally located throttle body. The throttle unit resembles a carburetor except that there is no fuel bowl, float or metering jets. Fuel is sprayed directly into the throttle bore(s) by the injector(s).

12 V is a 12 volt electrical system not (12 valves per cylinder) . How many cams would you need for that many valves per cylinder. lol.......... that would be a 72 valve engine.

It could be volts or valves
In this case it looks like valves
It looks like all the letters are describing an engine
Not the electrical system

12 valves meaning two per cylinder (one intake, one exhaust, only one camshaft)
