Spica Fuel Injection: Description
Fuel is supplied to the engine by injection into the intake port of each cylinder by means of four pumping elements (one per cylinder) whose delivery is controlled by a "control unit". A cam in control unit provides a base delivery according to opening of throttles and RPM. This base delivery is varied by compensating devices giving corrections for atmospheric pressure, engine temperature, cold starting, initial running, and fuel cut off on deceleration.
