摘要： PROBLEM TO BE SOLVED: To stably reduce emission of PM by executing appropriate control based on the distribution state of PM distributed in a cylinder inside space or on a cylinder inside wall surface.
SOLUTION: An ECU (electronic control unit) 60 calculates a space distribution coefficient α corresponding to the quantity of PM distributed in the cylinder inside space and a wall surface distribution coefficient β corresponding to the quantity of PM distributed on the cylinder inside wall surface based on at least the operation state of an internal combustion engine. The valve open timing of an exhaust valve 34 is retarded when the space distribution coefficient α is greater than a determination value X. Thus, the after-burn period of PM in which residual oxygen in a cylinder participates is extended, and space PM is reduced. The lift of an exhaust valve 34 is reduced, the flow velocity and the degree of turbulence at discharge of exhaust gas are increased when the wall surface distribution coefficient β is greater than a determination value Y. Then, wall surface PM and residual oxygen are suitably mixed and the reaction properties of both are increased, and the wall surface PM is reduced.

摘要翻译：要解决的问题：通过基于分布在气缸内部的空间内的气体分布状态或壁内的气缸内部的分布状态执行适当的控制来稳定地减少PM的排放。解决方案：ECU（电子控制单元）60计算与分配在气缸内空间中的PM的量对应的空间分布系数α和与分配在气缸内壁上的PM的量对应的壁面分布系数β 至少基于内燃机的运转状态来进行表面处理。当空间分配系数α大于确定值X时，排气阀34的阀打开正时被延迟。因此，气缸中的残留氧参与的PM的后燃烧期延长，并且空间PM减小。排气阀34的升程减小，当壁面分布系数β大于判定值Y时，废气排出时的流速和湍流程度增加。然后，壁面PM和残留氧适当地混合，两者的反应性能提高，壁面PM降低。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To control a state of the mixture of injected fuel with lubrication oil to a permissible range even when engine stop control is performed.SOLUTION: A direct injection type internal combustion engine 10 includes a recirculation passage 40 that recirculates to an intake passage 20 evaporative gas of the fuel mixed with the lubrication oil in an oil pan 38. An ECU (electronic control unit) 50 performs idle stop control for temporarily stopping the internal combustion engine 10 in an idle operation state when cooling water temperature of the internal combustion engine becomes equal to or higher than a permissible temperature. Further, the ECU 50 performs stop condition correction control for correcting the permissible temperature based on an oil dilution ratio of the lubrication oil and engine temperature. Accordingly, the oil dilution ratio can be confined to a permissible range by appropriately adjusting the frequency of performance and the duration time of the idle stop control according to the oil dilution ratio.

摘要： PROBLEM TO BE SOLVED: To suppress oil dilution by appropriately setting stop, without fail, allowing temperature, in response to temperatures of an internal combustion engine and alcohol concentration in fuel. SOLUTION: An ECU 60 executes engine stop control for temporarily stopping an internal combustion engine 10, when an engine temperature is a stop allowing temperature or higher. The stop allowing temperature is set lower as alcohol concentration in fuel is increased in a low temperature region and is set higher as alcohol concentration in fuel is increased in a high temperature region. Thus, opportunities for engine stop (EV operation) are increased in the low-temperature region so that engine drive operation and HV operation which are apt to increase in an oil dilution ratio can be avoided. In the high-temperature region, the engine drive operation and HV operation can be executed smoothly, while oil dilution ratio is suppressed. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：通过适当地设定停止来抑制油稀释，而不会由于内燃机的温度和燃料中的酒精浓度而允许温度。解决方案：当发动机温度为允许温度或更高温度的停止时，ECU60执行用于临时停止内燃机10的发动机停止控制。随着在低温区域中燃料中的醇浓度增加，停止允许温度降低，并且在高温区域中燃料中的醇浓度增加时设定为更高。因此，在低温区域中增加发动机停止（EV操作）的机会，从而可以避免容易增加油稀释比的发动机驱动操作和HV操作。在高温区域中，可以平稳地执行发动机驱动操作和HV操作，同时抑制油稀释比。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To stabilize an air-fuel ratio by appropriately controlling performance timing for operation where intake air vacuum is reduced according to a purge gas recirculating condition. SOLUTION: A direct injection internal combustion engine 10 includes a purge passage 44 extending from an oil pan 42 to an intake passage 20. When fuel mixed into lubricating oil in the oil pan 42 evaporates, the purge passage 44 recirculates the evaporated fuel to an intake system as purge gas. An ECU 60 estimates an oil dilution rate that is a rate of the lubricating oil diluted by mixing of injected fuel. At a high oil dilution rate, when reduced-cylinder operation, where a part of cylinders is maintained in a deactivation state, is performed, a purge gas rate with respect to intake air volume is excessively increased and the air-fuel ratio is easily disturbed. Therefore, the ECU 60 prohibits the reduced-cylinder operation when the oil dilution rate is higher than a predetermined reference value. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：通过根据吹扫气体循环条件适当地控制进气真空减少的操作的性能时序来稳定空燃比。直接喷射内燃机10包括从油盘42延伸到进气通道20的吹扫通道44.当油盘42中的润滑油中混合的燃料蒸发时，净化通道44将蒸发的燃料作为吹扫气体的进气系统。 ECU60估计作为通过混合喷射燃料而稀释的润滑油的速率的油稀释率。在高油稀释率下，当气缸的一部分保持在失活状态的减缸操作时，相对于进气体积的吹扫气体速率过大，空燃比容易受到干扰。因此，当油稀释率高于预定的参考值时，ECU60禁止减缸操作。版权所有（C）2010，JPO＆INPIT
