Abstract:In order to meet the demand of dynamic acquisition in diesel engine, study on dynamic acquisition of cylinder pressure based on digital signal processor (DSP) was conducted. The acquisition method and data process, data communication of dynamic acquisition were proposed, partial acquisition area between 50°CA( crank angle) before top dead center (TDC) and 100°CA after TDC has been presented. Digital signal processor (DSP) and high speed USB (universal serial bus) were introduced into dynamic acquisition, hardware and software for dynamic acquisition system have been designed. The bench test for acquisition performance and stability of this system was finished. Test result showed that dynamic acquisition system of cylinder pressure based on DSP could meet the requirement of diesel engine.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
