Abstract: A control apparatus 1 for the engine includes an ECU. When the operating region of the engine is in the EGR execution region B, the ECU performs the EGR control (step 2), and performs first coolant temperature control for controlling an IC coolant temperature TWic such that the temperature of intake air passing through an intercooler exceeds a dew-point temperature (step 14). Further, in a case where the operating region of the engine is in the EGR stop region C, the ECU performs second coolant temperature control for controlling the IC coolant temperature TWic such that the temperature of intake air having passed through the intercooler exceeds the dew-point temperature, assuming that the operating region of the engine has shifted to the EGR execution region B (step 17).

Abstract: A cooling system for a vehicle, includes a first cooling circuit including a first coolant passage and a first pump. The first pump is provided in the first coolant passage to circulate coolant in the first cooling circuit so as to cool a first device to a first temperature. A second cooling circuit includes a second coolant passage and a second pump. The second pump is provided in the second coolant passage to circulate coolant in the second cooling circuit so as to cool a second device to a second temperature. The second temperature is lower than the first temperature.

Abstract: An ignition apparatus for an internal combustion engine, comprising at least one ignition plug, an actuating circuit provided with first and second coil pairs corresponding to one ignition plug for generating spark discharge in the at least one ignition plug. First and second ignition signals respectively supplied to the first and second coil pair are generated so that a first discharge period and a second discharge period partially overlap with each other during an overlap discharge period, the overlap discharge period is made equal to a set overlap period, and a start timing of the first discharge period is prior to a start timing of the second discharge period. The first and second discharge periods are time periods of electric discharges generated by the first and second coil pairs. The set overlap period is set according to the first discharge period, a temporary cut threshold value, and a discharge start current value at the start timing of the first discharge period. The temporary cut threshold value is a minimum value of the discharge current value at which no temporary cut of the discharge current in the ignition plug occurs.

Abstract: An ignition control device for an internal combustion engine, which controls the number of times of ignition operation such that it becomes neither too large nor too small, according to a flowing state of a mixture in a cylinder. In the ignition control device, a target ignition timing is used as an in-cylinder flow parameter indicative of the strength of a tumble flow generated in a cylinder. When the target ignition timing is more advanced than a predetermined reference position, it is determined that the tumble flow is strong, and multiple ignition control is executed by setting the number of times of ignition to a plurality of times, whereas when the former is more retarded than the latter, it is determined that the tumble flow is not strong, and normal ignition control is executed by setting the number of times of ignition to only once.

Abstract: In a control device of an internal-combustion engine according to the disclosure, an intake throttle valve (25) for adjusting an EGR valve differential pressure (ΔPEGR) is provided, an EGR valve upstream pressure (PEGR0) is estimated by using a target fresh air amount (GAIRCMD) (step 6), a target differential pressure (ΔPEGRCMD) is set to a smaller value as the target fresh air amount (GAIRCMD) becomes smaller (FIG. 5), and a difference between the EGR valve upstream pressure (PEGR0) and the target differential pressure (ΔPEGRCMD) is set as a target valve downstream pressure (P1CMD) (step 7). By using the target fresh air amount (GAIRCMD), the EGR valve upstream pressure (PEGR0), and the target valve downstream pressure (P1CMD), the target EGR valve opening degree (LEGRCMD) is set (step 23), and an EGR valve (43) is controlled based on the target EGR valve opening degree (step 24).
