Disclosed is a control device applied to an internal combustion engine provided with a fuel vapor treatment system for treating collected fuel vapor by purging the collected fuel vapor into intake air downstream from an air flowmeter and an exhaust gas recirculation system for recirculating part of exhaust gas in the intake air using intake negative pressure. Other embodiments are described and claimed. The flexible strut is rotationally engaged in a base. As a result, the tip jack is held securely within the plug-in zone, while the intermediate zone absorbs the effects of the vibrational stresses. The technique further involves sending the DHCP message with the modified option portion to the DHCP server. The first converter includes a unit for controlling active power and a unit for controlling reactive power and the second converter includes a unit for controlling a voltage of a DC system and reactive power or AC voltage of a power system.
