    • A system and method for controlling a fuel supplied to an internal combustion engine having a fuel supply cut-off function which operates when the engine falls in a predetermined engine deceleration condition. When a fuel supply recovery is restarted immediately after the fuel supply cut-off, a residual quantity of fuel which remains on a wall of an intake air passage is estimated on the basis of an engine load immediately before the fuel supply cut-off is carried out, a fuel recovery increment quantity for incrementing the fuel supply to the engine at a time immediately after the fuel supply recovery is carried out is set on the basis of the estimated residual quantity of fuel and an interval of time for which the fuel supply cut-off is carried out, a basic fuel quantity determined according to an engine operating condition is corrected according to the fuel recovery increment quantity, and the corrected fuel quantity is finally supplied to the engine during the fuel supply recovery. Therefore, a response to an acceleration is remarkably improved due to the fuel recovery increment quantity determined with the residual fuel quantity taken into account.
    • 一种用于控制供给内燃机的燃料的系统和方法,所述燃料供给切断功能在发动机处于预定的发动机减速条件时工作。 当在燃料供给截止之后立即重新开始燃料供应恢复时,基于紧接在燃料供给截止装置之前的发动机负荷来估计残留在进气通道的壁上的剩余量的燃料 根据估计的燃料剩余量和燃料供给切断时间间隔来设定用于在执行燃料供给恢复之后的时刻增加向发动机的燃料供给的燃料回收增量量 按照燃料回收增量量校正根据发动机工作状态确定的基本燃料量,并且在燃料供给恢复期间最终将校正后的燃料量提供给发动机。 因此,由于考虑了剩余燃料量确定的燃料回收增量,所以对加速度的响应显着提高。

    • The invention is intended to suppress oscillatory combustion of a combustion apparatus. In the invention, acoustic closed ends are provided at an inlet side and an outlet side of the burner port unit, and the combustion apparatus is constituted so that the flame may be positioned between these closed ends, and a buffer chamber is provided at the inlet side. Thus, when the inlet side and outlet side of the burner port unit of the combustion apparatus are formed as acoustic closed ends, oscillatory combustion occurs easily. At this time, when the intake tube communicates at the upstream side of the inlet side closed end, and an exhaust tube communicates at the downstream side of the outlet side closed end, if the length of the intake tube and exhaust tube is changed, the air ratio and combustion amount for generating oscillatory combustion remain constant, and the oscillation frequency and oscillation pressure remain constant. In such condition, when a sound absorbing unit is provided in the buffer chamber, oscillation does not occur, and if the intake tube or exhaust tube is extended, oscillation does not occur.
    • 本发明旨在抑制燃烧装置的振荡燃烧。 在本发明中,在燃烧器端口单元的入口侧和出口侧设置声学闭合端,并且燃烧装置构成为使得火焰可以位于这些封闭端之间,并且在入口处设置有缓冲室 侧。 因此,当燃烧装置的燃烧器端口单元的入口侧和出口侧形成为声闭合端时,容易发生振荡燃烧。 此时,当进气管在入口侧封闭端的上游侧连通,排气管在出口侧封闭端的下游侧连通时,如果进气管和排气管的长度改变, 空气比和产生振荡燃烧的燃烧量保持恒定,并且振荡频率和振荡压力保持恒定。 在这种情况下,当在缓冲室中设置吸音单元时,不发生振动,如果进气管或排气管延伸,则不会发生振荡。
