用于调节车辆的内燃机的增压空气压力的方法和装置
摘要：
一种用于调节车辆(1)的内燃机(2)的增压空气压力(p)的方法，该车辆具有：废气涡轮增压器(4)；新鲜气体供应装置(5)；具有空气处理装置(23)的车辆通风系统；能通过废气涡轮增压器(4)增压的压缩机(6)；和发动机控制装置(31)，该方法包括以下方法步骤：检测对内燃机(2)的转矩要求，测定当前增压空气压力(p)并且测定车辆通风系统的当前压力；将当前增压空气压力(p)与和该转矩要求相应的额定增压空气压力(Psoll)进行比较并且将车辆通风系统的测定的当前压力与车辆通风系统的额定运行压力进行比较；并且当测定的当前增压空气压力(p)小于相应的额定增压空气压力(Psoll)和当车辆通风系统的当前压力大于或者等于车辆通风系统的额定运行压力时，就通过阻止向压缩机(6)输送由废气涡轮增压器(4)供应的被压缩的空气来调节增压空气压力(p)；本发明还涉及一种相应的装置。
摘要（英）：

A method is provided for regulating a charge air pressure of an engine having an exhaust gas supercharger, a fresh gas supply device, an air system having an air treatment system and a compressor chargeable by the supercharger, and an engine controller. The method detects an engine torque requirement; determines a current charge air pressure and a current pressure of the air system; compares the current charge air pressure to a target charge air pressure corresponding to the torque requirement, compares the current air system pressure to a target operating air system pressure, and regulates the charge air pressure by suppressing supply of compressed air from the supercharger to the compressor when the current charge air pressure is less than the corresponding target charge air pressure and the current pressure of the air system is greater than or equal to the target operating pressure of the air system.
