    摘要： To provide an engine control device including a transient-state determination-processing unit 24a that determines whether an operating state of an engine is in a transient state of shifting to an acceleration state based on a change amount of a target throttle opening degree, and a transient-state correction-processing unit 24b that retards an ignition timing by a predetermined amount set by the change amount when the transient-state determination-processing unit determines that the operating state of the engine is in the transient state.

    摘要： A four-cylinder engine includes a cylinder body (3), a cylinder head (4), and an ignition device (27) including spark plugs (14). The engine also includes an intake device (16) connected to intake ports (9), an exhaust device (23) connected to exhaust ports (10), four pistons (6), and a crankshaft (8) connected to the pistons (6) by connecting rods (7). Explosion intervals of the four cylinders are 270°, 180°, 90°, and 180° as crank angles. The engine further includes an discomfort eliminator (35) which, when the engine speed is lower than a predetermined value, makes the indicated mean effective pressure of at least one of two cylinders having an explosion interval of 90° lower than the indicated mean effective pressures of other cylinders having an explosion interval of not 90°. This invention can provide a four-cylinder engine which causes unequal-interval explosions but produces little change in driving energy per unit time in an operating state in which an occupant is liable to feel torque fluctuations.

    摘要翻译： 四缸发动机包括气缸体（3），气缸盖（4）以及包括火花塞（14）的点火装置（27）。 发动机还包括连接到进气口（9）的进气装置（16），连接到排气口（10）的排气装置（23），四个活塞（6）以及连接到活塞（6）的曲轴（8） ）通过连杆（7）。 四个气缸的爆炸间隔为曲柄角270°，180°，90°和180°。 发动机还包括不适消除器（35），当发动机转速低于预定值时，该不适消除器（35）使两个气缸中至少一个气缸的爆炸间隔为90°的指示平均有效压力低于指示平均有效压力 其他气缸的爆炸间隔不是90°。 本发明可以提供一种四缸发动机，其在乘员容易感觉到扭矩波动的运行状态下产生不等间隔爆炸，但每单位时间的驱动能量变化很小。
