    • An internal combustion engine is provided with at least one modulator for adjusting an air mass in a cylinder. It is also provided with an injection valve for metering fuel to which fuel is supplied via a fuel supply device. A maximum fuel quantity (MFF_MAX) which can be metered to the cylinder per working stroke is determined. Depending on the maximum meterable fuel quantity (MFF_MAX), a maximum producible torque (TQ_MAX) is determined. An air mass flow (MAF_CYL) is determined depending on an air/fuel ratio (LAM_SP) to be adjusted and the maximum meterable fuel quantity (MFF_MAX) is adjusted by controlling the at least one modulator for adjusting the air mass. The injection valve is controlled in accordance with the maximum meterable fuel quantity (MFF_MAX) when the required torque (TQ_REQ) is greater or equal the maximum producible torque (TQ_MAX).
    • 一个内燃机设置有至少一个用于调节气缸中空气质量的调制器。 它还设置有用于计量经由燃料供应装置供应燃料的燃料的喷射阀。 确定可以每工作行程计量到气缸的最大燃料量(MFF_MAX)。 根据最大可燃量(MFF_MAX),确定最大可产生转矩(TQ_MAX)。 根据要调节的空气/燃料比(LAM_SP)来确定空气质量流量(MAF_CYL),并且通过控制用于调节空气质量的至少一个调制器来调整最大可计量燃料量(MFF_MAX)。 当所需转矩(TQ_REQ)大于或等于最大可产生转矩(TQ_MAX)时,根据最大可计量燃料量(MFF_MAX)来控制喷射阀。

    • A fuel control method for a multi-cylinder engine, a fuel injection amount control method for an engine and an engine operating state discrimination method using the fuel injection amount control method, a propelling device for multiple engine, and a fuel injection control method at a crush astern in an engine with a speed reducing and reversing machine for marine use. The fuel control method for the multi-cylinder engine having a rotation recognizing means recognizing the rotating amount of a crankshaft by cylinders before the combustion cycle of a cylinder concerned. When the injection and supply of a fuel from an injector into the cylinder of the six cylinders are disabled, the number of the cylinders to be recognized by the rotation recognizing means is changed so that the rotating amount of the crankshaft for each of all the six cylinders in which the combustion cycles are continued to each other before the combustion cycle of the cylinder can be recognized. The supply of the fuel of the injector which supplies the fuel to the cylinders having a combustion cycle interval matching that of the cylinder to which the fuel cannot be supplied is controllably stopped so that the combustion cycle intervals between the cylinders on both front and rear sides of the fuel-unsupplied cylinder in the combustion cycle can be uniformed.
