中文摘要:针对DPF的再生技术难题,研究了基于机内技术的DPF再生控制策略,通过机内措施改变柴油机的燃烧,提升排温,在柴油机不作任何改动、不附加任何辅助系统的情况下实现过滤体的安全有效再生。首先,提出了基于柴油机机内控制技术的DPF再生控制技术方案,并设计了DPF再生监控系统。然后,建立了基于压差、柴油机转速和负荷多参数的碳烟加载模型,提高了再生的准确性和一致性;最后,设计了包含柴油机转速和负荷因素的提升柴油机排温的措施模型和再生温度控制模型,确保了DPF的再生过程有效且安全。试验结果表明,采用设计的再生控制策略,DPF的整个再生过程是有效且安全的。

Key Words:Diesel engine DPF regeneration Control strategy
Abstract:Control strategy of DPF regeneration based on inner diesel engine-based machine is developed, which enhances the exhaust temperature by using of inner machine measures to change the combustion of diesel engines. This method can achieve safe and effective DPF regeneration without making any changes and adding auxiliary systems in the diesel engine. Firstly, technical program and monitoring system of DPF regeneration based on inner diesel engine-based machine is proposed and designed. Secondly, soot loading model based on differential pressure, engine speed and load is established to improve the accuracy and consistency of DPF regeneration. Finally, the measures model of exhaust temperature containing the diesel engine speed and load factors, as well as the regeneration temperature model, is designed to ensure process of DPF regeneration is effective and safe. The experimental result shows that the process of DPF regeneration is effective and safe by using of this regeneration method.

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.
