摘要： An abnormality diagnosis device introduces a pressure into a reference-pressure detecting portion by utilizing a pressure introducing portion to detect a reference pressure correlative to a reference orifice, detects a purge-valve closed pressure that is a pressure in an evaporation system of when a pressure is introduced into the evaporation system by the pressure introducing portion after the purge valve is controlled to be closed, and detects a purge-valve open pressure that is a pressure in the evaporation system of when a pressure is introduced into the evaporation system by the pressure introducing portion after the purge valve is controlled to be open. The abnormality diagnosis device determines whether a leakage abnormality of the evaporation system and a fixed open abnormality are generated, based on a magnitude relation between the reference pressure, the purge-valve closed pressure, and the purge-valve open pressure.

摘要： A leakage diagnosis apparatus is applied to an evaporated-gas purge system including a negative-pressure sensor and a pressure detecting portion. The negative-pressure sensor introduces a negative pressure into an evaporation system. The pressure detecting portion detects the pressure in the evaporation system. The leakage diagnosis apparatus includes a leakage-diagnosis portion and a determining portion. The leakage-diagnosis portion executes a leakage diagnosis to determine whether a leakage of the evaporation system is generated. The determining portion determines whether an evaporated-gas amount in the evaporation system is in an excessive state while the internal combustion engine is stopped. The leakage-diagnosis portion prohibits or terminates the leakage diagnosis, when the determining portion determines that the evaporated-gas amount is in the excessive state.

摘要： A wireless communication apparatus mounted on a mobile body includes a transmitter and a receiver. The transmitter is configured to transmit position information indicating a position to which the mobile body is scheduled to move, to a server apparatus. The receiver is configured to receive communication quality information indicating a communication quality corresponding to the position, from the server apparatus. The transmitter is configured to transmit the date at a communication position specified based on the communication quality information.
