    • When alcohol mixing fuel is supplied to an internal combustion engine, an intake air flow rate is detected and a basic amplitude amount α of an upstream target air-fuel ratio abyfr corresponding to this detected intake air flow rate is calculated. Next, alcohol concentration in the fuel (in more detail, ethanol concentration Cetha) and a cooling water temperature (or an intake air temperature) are detected, hydrogen concentration Ch in a mixing exhaust gas is calculated based on the detected ethanol concentration Cetha and the detected cooling water temperature (or the detected intake air temperature) amplitude gain β corresponding to the calculated hydrogen concentration is calculated and finally, an amplitude amount (α×β) of the upstream target air-fuel ratio is calculated.
    • 当将混合燃料的燃料供应到内燃机时,检测进气流量,并且计算与该检测到的进气量对应的上游目标空燃比abyfr的基本振幅量α。 接下来,检测燃料中的酒精浓度(更详细地,乙醇浓度Cetha)和冷却水温度(或进气温度),基于检测到的乙醇浓度Cetha计算混合排气中的氢浓度Ch 检测到的冷却水温度(或检测到的进气温度)振幅增益&bgr; 计算与计算出的氢浓度对应的最终目标空燃比的最大值(α×&bgr)。

    • In a predetermined low-temperature startup state (in a rich atmosphere), in principle, over-advanced ignition control for advancing ignition timing beyond MBT and intake-synchronized injection control for causing the entire amount of to-be-injected fuel to undergo intake-synchronized injection are executed. Thus, the peak of intra-cylinder temperature increases, and the amount of port-adhering fuel decreases, whereby the emission amount of unburnt HC can be reduced. However, when the PM emission amount exceeds a PM permissible amount, instead of the intake-synchronized injection control, there is performed processing for causing a portion of the to-be-injected fuel to undergo intake-unsynchronized injection and causing the remaining fuel to undergo intake-synchronized injection. Thus, the amount of intra-cylinder-adhering fuel decreases, and the partial oxidation reaction of the intra-cylinder-adhering fuel, which is a cause of generation of PM, is suppressed. As a result, the PM emission amount decreases, whereby the PM emission amount can be suppressed to the PM permissible amount.
    • 在预定的低温启动状态(丰富的气氛)中,原则上超过超过MBT的点火正时超前点火控制和进气同步喷射控制,以使全部喷射的燃料量进入 执行同步注入。 因此,气缸内温度的上升增加,并且端口附着燃料的量减少,从而可以减少未燃HC的排放量。 然而,当PM排放量超过PM允许量时,代替进气同步喷射控制,执行使待喷射燃料的一部分进行进气不同步喷射的处理,并使剩余的燃料 进行摄像同步注入。 因此,气缸内附着燃料的量减少,并且抑制作为PM的产生原因的气缸内附着燃料的部分氧化反应被抑制。 结果,PM排放量减少,从而可以将PM排放量抑制在PM容许量。
