Abstract: An ignition device is provided for an idle stop & go system (ISG)-equipped vehicle using a liquefied petroleum gas (LPG) as a fuel.

Also, in an emergency, the LPG and auxiliary LPG switches are simultaneously switched off, the fuel cut-off solenoid valves are quickly switched off and the fuel pump motor is stopped to quickly cut off the fuel supply and prevent a secondary accident in advance.

Abstract: A fuel injection controller includes an increase control portion applying the boost voltage to the coil to increase a coil current to a first target value, and a constant current control portion applying a voltage to the coil to hold the coil current to a second target value. A threshold is an energization time period that is necessary to reach a boundary point between a seat throttle area of a property line and an injection-port throttle area of the property line from an energization start time point. An initial-current applied time period is from the energization start time point that the boost voltage starts to be applied to the coil to a time point that the coil current is decreased to the second target value. The increase control portion controls the coil current such that the initial-current applied time period is less than the threshold.
