    摘要： Inside of an engine exhaust passage, in order from an upstream side, a hydrocarbon feed valve (16), oxidation catalyst (13), exhaust purification catalyst (14), and NO x selective reduction catalyst (15) are arranged. By lowering the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (14) by a predetermined period while maintaining it lean, the NO x is reduced in the exhaust purification catalyst (14) and the NO x which was not reduced at the exhaust purification catalyst (14) is reduced by the ammonia which is adsorbed at the NO x selective reduction catalyst (15). The air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (14) is sometimes switched from lean to rich. At this time, the ammonia which was generated at the exhaust purification catalyst (14) is adsorbed at the NO x selective reduction catalyst (15).

    摘要翻译： 在发动机排气通路的内部，从上游侧依次配置有烃供给阀（16），氧化催化剂（13），排气净化催化剂（14）以及选择还原型NOx催化剂（15）。 通过将流入排气净化催化剂（14）的排气的空燃比维持为稀薄状态的同时降低规定时间，使排气净化催化剂（14）中的NOx减少，在排气净化催化剂 排气净化催化剂（14）被吸附在选择还原型NOx催化剂（15）上的氨还原。 流入排气净化催化剂（14）的排气的空燃比有时从稀转换为浓。 此时，在排气净化催化剂（14）产生的氨被吸附在选择还原型NOx催化剂（15）上。

    摘要： The control system (100) comprises an engine (10), a MG (20), a high-voltage battery (30), a first load (40), a second load (50) and an ECU (60). When the ECU determines that a signal requesting for the driving of the second load has been detected, the ECU outputs to the engine a control signal for starting power generation by the MG. At the same time, the ECU outputs the control signal to the power supply control circuit connected to the second load such that the ECU disconnects the electric connection between the high-voltage battery and the second load. When the electric connection between the high-voltage battery and the second load is disconnected, the power supply is prohibited from the high-voltage battery to the second load during power generation by the MG.
