    • A control system for an internal combustion engine calculates an amount of evaporative fuel supplied to the combustion chamber of the engine based on the total amount of evaporative fuel and depending on dynamic characteristics of the purged gas. Then, the system determines a required amount of fuel to be injected by a fuel injection valve based on the amount of evaporative fuel supplied to the combustion chamber. The rate of change of the air-fuel ratio correction coefficient based on this ratio of the actual amount is set to the desired amount. The control system also calculates an injected fuel ratio of an amount of fuel injected to an amount of total fuel to be supplied to the combustion chamber, and controls the ignition timing based on the injected fuel ratio and depending on operating conditions of the engine. The control system further calculates an amount of fuel to be injected and the ratio of the amount of fuel to be injected to the amount of fuel to be purged from the canister based on operating conditions of the engine, and based on this ratio, controls the purge control valve and at the same time decreases the amount of fuel to be injected, while setting a limit to this ratio for maintaining the linear relationship of the valve opening period of the fuel injection valve and the fuel injection amount.
    • 用于内燃机的控制系统基于蒸发燃料的总量并且取决于净化气体的动态特性来计算供应到发动机的燃烧室的蒸发燃料的量。 然后,该系统基于供应到燃烧室的蒸发燃料的量来确定由燃料喷射阀喷射的所需燃料量。 基于该实际量的比率的空燃比校正系数的变化率被设定为期望的量。 控制系统还计算喷射的燃料量与将被供应到燃烧室的总燃料量的喷射燃料比,并基于喷射的燃料比并根据发动机的运行条件来控制点火正时。 控制系统进一步基于发动机的运行条件计算要喷射的燃料的量以及要喷射的燃料的量与将从滤罐清除的燃料的量的比率,并基于该比率来控制 同时减少喷射的燃料量,同时设定对该比率的限制,以保持燃料喷射阀的阀门开启时间与燃料喷射量的线性关系。

    • A control device for an internal combustion engine, the control device includes an electronic control unit configured to: (a) control execution of an automatic stop to stop an engine operation based on meeting of an automatic stop condition, (b) control execution of a purge cut to stop the release of the fuel vapor by the purge device, (c) estimate a concentration of the fuel vapor remaining in the intake passage in a state where the purge cut is executed as a purge gas concentration when engine temperature is higher than a reference temperature, and delay the execution of the automatic stop, even when the automatic stop condition is met, until the purge gas concentration decreases to be equal to or lower than a reference concentration, and (d) execute the automatic stop, without delaying the execution of the automatic stop, when the engine temperature is equal to or lower than the reference temperature.
