    • An ignition timing controlling apparatus for an engine includes an ignition timing map in which high-torque timings are stored, an ECU for changing a high-torque timing obtained from the ignition timing map into a fuel-conserving ignition timing, and an advance angle target amount map in which advance angle target amounts with which the high-torque timing is to be changed into the fuel-conserving ignition timing are stored. The ECU is operable to calculate an advance angle target amount for each of cylinders of the engine based on the advance angle target amount map when a running state of a vehicle is in a cruize state in which little acceleration or deceleration is included, and also to execute advance angle control of changing the ignition timing of each of the cylinders stepwise with respect to the advance angle target amount for each of the cylinders.
    • 用于发动机的点火正时控制装置包括其中存储有高扭矩定时的点火正时图,用于将从点火正时图获得的高扭矩定时改变为燃料保持点火正时的ECU和提前角目标 存储要将高转矩定时改变为节油点火正时的提前角目标量的量图。 ECU可操作以当车辆的行驶状态处于包含少量加速或减速的临时状态时,基于提前角目标量图来计算发动机的每个气缸的提前角目标量,并且还 执行相对于每个气缸的提前角目标量逐步改变每个气缸的点火正时的提前角控制。
