本文在实验研究的基础上,对增压柴油机采用进气旁通的一些规律性问题进行了分析,指出影响柴油机性能的最主要因素是控制增压比及压气机绝热效率。当控制适当的增压比时,进气旁通增压柴油机的扭矩特性、动力性和经济性都获得较大改善,而采用高效率、小流量、高压比的增压器是充分发挥进气旁通系统优点的关键。 Based on the experimental research, this paper analyzes some regularities of turbocharged diesel engine using intake bypass, and points out that the most important factor affecting the performance of diesel engine is the control of turbocharger ratio and compressor adiabatic efficiency. When controlling the appropriate turbocharger ratio, the torque characteristics, power and economy of the intake bypass turbocharged diesel engine are greatly improved, while the turbocharger with high efficiency, low flow rate and high pressure ratio is to make full use of the intake air The key to bypass system benefits.
