摘要： The problem to be solved by the present invention is to provide a fuel injection controller capable of bringing the fuel injection amount closer to the ideal one. Solving Means We let the throttle opening at P2 be denoted by TH0. Here, P2 is a specific time later than the peak value of an intake pipe internal pressure PB of a previous cycle. In the cycle, P3 is a specific point that is set immediately before the calculation of the injection time shown by a rectangle filled with diagonal lines. We let the throttle opening at P3 be denoted by TH1. The injection amount is corrected based on a variation in correction time (ta0 to ta1). Effect Point P2 is later than point P1 as (f) in Fig. 4 . Therefore, the correction is completely unaffected or only slightly affected by the intake pipe internal pressure, if affected at all, thus ensuring close-to-ideal correction.

摘要： The problem to be solved by the present invention is to provide a fuel injection controller capable of bringing the fuel injection amount closer to the ideal one.
Solving Means
We let the throttle opening at P2 be denoted by TH0. Here, P2 is a specific time later than the peak value of an intake pipe internal pressure PB of a previous cycle. In the cycle, P3 is a specific point that is set immediately before the calculation of the injection time shown by a rectangle filled with diagonal lines. We let the throttle opening at P3 be denoted by TH1. The injection amount is corrected based on a variation in correction time (ta0 to ta1).
Effect
Point P2 is later than point P1 as (f) in Fig. 4 . Therefore, the correction is completely unaffected or only slightly affected by the intake pipe internal pressure, if affected at all, thus ensuring close-to-ideal correction.

摘要翻译： 本发明要解决的问题是提供一种能够使燃料喷射量接近理想值的燃料喷射控制器。 解决方法我们让P2处的油门开度用TH0表示。 这里，P2是比前一个循环的进气管内压PB的峰值晚的特定时间。 在这个循环中，P3是一个特定的点，它是在计算由填充对角线的矩形表示的注入时间之前立即设置的。 我们让P3处的油门开度用TH1表示。 基于校正时间的变化（ta0至ta1）校正喷射量。 如图4中的（f），效应点P2比点P1更迟。因此，如果受到影响，修正完全不受影响或仅受进气管内部压力的轻微影响，从而确保接近理想的修正。
