摘要：

       为了提升发动机控制系统的性能，支持基于汽油- 柴油混合燃料的新型燃烧研究，开发了新一代压燃发动机控制平台。利用汽车级的多核单片机MPC5746R，实现了系统的集成式架构；基于汽车开发系统架构规范开发了底层软件，设计了两个内核之间的协调机制，实现了发动机相位识别、喷射控制和缸压采集等复杂设备驱动；在应用层软件中集成了发动机控制和燃烧控制( 燃烧指标计算、燃烧模式识别和燃烧反馈控制) 功能。在一台1.9 L 柴油机上进行了试验。结果表明：利用该电控平台，能够实时采集缸压信息，计算燃烧指标，并进行燃烧反馈控制。

Abstract:

A new control platform for compression ignition engines was developed to improve the performance of engine control systems and support the research of new combustion modes with gasoline-diesel blended fuel. An integration architecture was introduced based on a new automotive grade multi-core microcontroller
MPC5746R. Automotive Open System Architecture (AUTOSAR) rules were applied to the basic software and coordination mechanisms between two cores were designed. Engine position detection, injection control and cylinder pressure acquisition were included in the complex drivers. Engine control and combustion control (combustion indexes calculation, combustion mode recognition and feedback combustion control) were integrated into the application software. Verification tests were done on a 1.9 L diesel engine. The results show that it is able to acquire cylinder pressure information, calculate combustion indexes and do the feedback combustion control in real-time applications by using this control platform.
