摘要： A vehicle electrical system includes a battery, a customer connection point, a switch electrically connected in series between the battery and the customer connection point, a computer communicatively coupled to the switch, and a transceiver communicatively coupled to the computer. The computer is programmed to instruct the switch to open in response to a state of charge of the battery decreasing below a charge threshold, receive an input selecting a time limit, and instruct the transceiver to transmit a message to a remote server upon determining that the state of charge of the battery will decrease below the charge threshold in less than the time limit from a current time.

摘要： An internal combustion engine includes a control unit determining the occurrence or non-occurrence of dew condensation in a tip portion of a nozzle based on a nozzle heat receiving amount of an injector and a nozzle tip temperature of the injector at a point in time when ignition is turned OFF and performing nozzle corrosion prevention control when the dew condensation is determined to occur in the nozzle tip portion. The control unit calculates a nozzle tip temperature reduction rate based on the nozzle heat receiving amount, calculates a dew point arrival time based on the reduction rate, and determines the occurrence or non-occurrence of the dew condensation in the nozzle tip portion based on the dew point arrival time.

摘要： In an internal combustion engine, an ignition plug is arranged near a center of an upper wall surface of a combustion chamber, and is used to ignite air-fuel mixture. Fuel injected from a port fuel injection valve is directed toward the center of the combustion chamber when the intake valve is open. The engine is configured to generate a tumble flow in a cylinder. A flow speed of gas around the ignition plug during ignition is controlled by changing a pattern of tumble flow between an ordinary first tumble flow pattern and a different second tumble flow pattern on the basis of an engine rotation speed. The tumble flow having the second pattern is generated by overlapping a fuel injection period of the port fuel injection valve with the open period of the intake valve.
