摘要： A homogeneous charge compression ignition engine that prevents knocking and misfires when changing output and when the load or air-fuel ratio changes due to one reason or another when operating under a predetermined condition. A controller determines whether or not the air-fuel ratio is changing in such a manner that there is a possibility of knocking or misfires occurring by using a map defining a range, in which stable homogeneous charge compression ignition operation is enabled, in relation with the air-fuel ratio and the intake air temperature. When the air-fuel ratio indicates that there is a possibility of knocking or misfires occurring, the controller controls an intake air temperature adjustor to adjust the intake air temperature based on the map.

摘要： At high temperature, namely, when the temperature of intake air is higher than a predetermined normal temperature range, an ECU (25) controls a variable valve timing mechanism (24) such that the timing for closing an exhaust valve (9) is adjusted to a retard side, thereby reducing the amount of high-temperature internal EGR gas to avoid the occurrence of pre-ignition. At intermediate load and high load, the ECU (25) makes the retard amount of the timing for closing the exhaust valve (9) larger than that at low load, thereby reducing the amount of internal EGR gas. At intermediate load and in an intermediate-revolution range or a high-revolution range, the rotating speed of an electric motor (16) is increased to raise a supercharging pressure exerted by a supercharger (17). At high load and in the high-revolution range, the electric motor (16) for the supercharger (17) and an EGR control valve (22) are controlled such that the supercharging pressure rises and the amount of external EGR gas increases as the temperature of intake air detected by a temperature sensor (26) rises.
摘要翻译：在高温时，即当进气温度高于预定的常温范围时，ECU（25）控制可变气门正时机构（24），使得关闭排气门（9）的时间被调整为延迟侧，从而减少高温内部EGR气体的量，以避免发生预点火。在中负荷和高负载下，ECU（25）使得关闭排气门（9）的时间的延迟量大于低负载时的延迟量，从而减少内部EGR气体的量。在中间载荷和中转速度或高转速范围内，电动机（16）的转速增加，以提高由增压器（17）施加的增压压力。在高负载和高转速范围内，控制增压器（17）的电动机（16）和EGR控制阀（22），使得增压压力升高，外部EGR气体的量随温度由温度传感器（26）检测到的进气量升高。

摘要： An HCCI engine operated in HCCI and SI combustion modes. The engine includes an external EGR apparatus for performing external EGR. A control unit executes combustion control by specifying either one of HCCI and SI combustion ranges based on the driving state of the engine and a combustion range map for specifying the combustion range in accordance with the driving state. The map includes the HCCI and SI combustion ranges and a switch preparation combustion range, which is included in the SI combustion range and extends along a boundary between the SI combustion range and the HCCI combustion range. The control unit lowers the temperature in the combustion chamber when the switch preparation combustion range is specified by reducing the amount of internal EGR or performing the external EGR.
