The invention relates to a method of controlling intake manifold injection of a fuel injection system belonging to an internal combustion engine having an intake manifold injector and a direct injector in a combined type which have a common fuel low-pressure system (4). An injection valve (13) of the intake manifold injector is controlled for fuel intake manifold injection of a predetermined fuel amount in a control duration time period calculated by an electronic controller (20). In a real-time operating point period of the internal combustion engine and the fuel injection system, based on the fuel pressure trend which is real-time, specifically measured and provided of an operating point in motor operation previously, the control duration time period (TE1, TE2) for the injection valve is calculated by the electronic controller (20). 本发明涉及用于控制带有具有共同的燃料低压系统（4）的进气管喷射设备和直接喷射设备的从属于内燃机的燃料喷射系统的进气管喷射的方法，其中，所述进气管喷射设备的喷射阀（13）在被电子的控制器（20）所求取的所述喷射阀的操控持续时间期间为了预先给定的燃料量的燃料进气管喷射而被操控，并且其中，在内燃机的和燃料喷射系统的实时的运行点期间，基于先前在马达运行中运行点
