Abstract
An engine system includes an internal combustion engine to which fuel is supplied by solenoid operated pump/injectors. Power is supplied to the injectors by a drive unit which is controlled by a control unit. The engine includes a starter motor which is energized from a battery by way of a time delay relay which comes into operation when a starter switch is actuated. The control unit is arranged so that energization of the starter when the switch is moved to the start position is delayed until the solenoids of all the pump/injectors have been energized to their maximum extent. When the cranking of the engine reaches a predetermined value the injectors are allowed to operate at about half stroke, each injector being operated at least twice to provide the required amount of fuel for starting purposes. Once the engine has started the system does not revert to normal operation until a sufficient period has lapsed for the terminal of the battery to rise to a value such that the pump/injectors are capable of supplying the required amount of fuel in a single stroke.
