Abstract: According to an embodiment of the present invention, a control method of an engine may comprise: a step of sensing or calculating an actual supply amount or a target amount of EGR gas supplied from an exhaust line to an intake line, and then comparing the sizes of the actual supply amount and the target amount; a step of sensing the opening degree of an EGR valve installed on an EGR line and controlling the actual supply amount of the EGR gas supplied to the intake line; a step of fixing the opening degree of a bypass valve at a minimum opening rate when the actual supply amount of the EGR gas is estimated to be smaller than the target supply amount of the EGR gas, and the opening degree of the EGR valve is estimated to be a maximum value; and a step of controlling the opening degree of the EGR valve while fixing the opening degree of the bypass valve at the minimum opening rate, wherein the bypass valve is installed on a bypass line bypassing an electric turbocharger. Therefore, when the actual supply amount of the EGR gas does not reach the target supply amount, the bypass valve is fixed at a minimum opening degree (step 1) before closed, and the EGR valve on the EGR line and a charging control valve on the rear end of the electric turbocharger are simultaneously or selectively controlled, thereby precisely and stably supplying the EGR gas.
Abstract translation: 根据本发明的实施例，发动机的控制方法可以包括：检测或计算从排气管线供应到进气管线的EGR气体的实际供给量或目标量的步骤，然后将尺寸 的实际供应量和目标金额; 检测安装在EGR管线上的EGR阀的开度并控制供给到进气管线的EGR气体的实际供给量的步骤; 当EGR气体的实际供给量被估计为小于EGR气体的目标供给量时，将旁通阀的开度固定为最小开度的步骤，并且估计EGR阀的开度 成为最大值; 以及在以最小开度固定旁通阀的开度的同时控制EGR阀的开度的步骤，其中旁通阀安装在旁路电动涡轮增压器旁路旁。 因此，当EGR气体的实际供给量未达到目标供给量时，在关闭前将旁通阀固定为最小开度（步骤1），并且EGR管路上的EGR阀和充气控制阀开 同时或选择性地控制电动涡轮增压器的后端，从而精确且稳定地供应EGR气体。
