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 excellently hold combustibility, even if an estimation error of an alcohol concentration exists when starting.SOLUTION: An ECU 50 injects fuel exceeding an allowable limit in a transport delay out of fuel tried to be injected from an intake passage injection valve 26, from a cylinder injection valve 28 as a transport delay increase quantity, when simultaneously using intake passage injection and cylinder injection when starting an engine. Thus, even when an estimation error is caused when estimating an alcohol concentration in the fuel, a cylinder injection quantity for improving startability can be increased. Thus, influence of the estimation error on an intake passage injection quantity and a transport delay increase quantity is restrained, and starting time combustibility can be excellently held. A variation in the air-fuel ratio and the deterioration in exhaust emission caused by the transport delay of the intake passage injection are restrained, and the startability and an exhaust characteristic can be improved.
