    • In turbocharged engines, there is the problem that, in particular under load, the ambient pressure (AMP) cannot be determined directly from the measurement values of a charge-pressure sensor (8). In order to avoid the installation of a further pressure sensor which is suitable for the detection of the ambient pressure (AMP), it is proposed according to the invention that, during a negative load step of the internal combustion engine in which a switch takes place from supercharged engine operation into non-supercharged engine operation, the charge-pressure sensor (8) measures the transient profile of the charge pressure (PUT). A value for the ambient pressure (AMP) is determined from the transient profile of the charge pressure (PUT). By means of the pressure value for the present ambient pressure (AMP), it is possible to optimize the engine operation for example when travelling up a slope.
    • 在涡轮增压发动机中,存在的问题是,特别是在负载下,环境压力(AMP)不能直接从充气压力传感器(8)的测量值确定。 为了避免安装适合于检测环境压力(AMP)的另外的压力传感器,根据本发明提出,在内燃机的负荷阶段,发生开关的负荷阶段 从增压发动机运转到非增压发动机运行,充气压力传感器(8)测量充气压力(PUT)的瞬态曲线。 环境压力(AMP)的值由充电压力(PUT)的瞬态曲线确定。 借助于当前环境压力(AMP)的压力值,例如当沿斜坡行进时,可以优化发动机操作。

    • The invention relates to a method of determining the ambient pressure which is performed in a turbocharged engine comprising a throttle which is disposed between a heat exchange chamber, known as an intercooler, and an intake manifold. In addition, a compressor is provided in order to compress the air in the heat exchange chamber, and the engine is equipped with means for indicating the pressure in said chamber. The inventive method comprises the following steps consisting in: detecting the opening of the throttle; measuring the pressure (MAP_UP) in the heat exchange chamber; and determining the ambient pressure (AMP) by measuring the pressure (MAP_UP) in the heat exchange chamber at a pre-determined moment which is defined in relation to a characteristic point of the curve (24) representing the pressure (MAP_UP) in the heat exchange chamber as a function of time, the ambient pressure (AMP) being equal to the pressure measured in the heat exchange chamber.
    • 本发明涉及一种确定在涡轮增压发动机中执行的环境压力的方法,其包括设置在被称为中间冷却器的热交换室和进气歧管之间的节气门。 此外,为了压缩热交换室内的空气而设置有压缩机,发动机配备有用于指示所述室内的压力的装置。 本发明的方法包括以下步骤:检测节气门的开度; 测量热交换室中的压力(MAP_UP); 以及通过在预定力矩下测量热交换室中的压力(MAP_UP)来确定环境压力(AMP),所述预定力矩相对于表示热量中的压力(MAP_UP)的曲线(24)的特征点而定义 交换室作为时间的函数,环境压力(AMP)等于在热交换室中测量的压力。
