从宏观上看,内燃机的工作是稳定的,从微观上看则各循环之间的热力参数并非均匀一致,而是存在着波动.柴油机转速的波动,早已为人们所注意,但对喷油、进气以及燃烧过程的波动,则研究者不多,且缺乏与结构、使用状况等的联系.本文应用实时性强、采样频率高的两台仪器,在不同负荷、不同工况、不同喷油器结构下,测录了它们对循环波动的影响,并初步探索波动的机理.
From a macroscopic point of view, the work of the internal combustion engine is stable, from the microscopic point of view the thermal parameters of the cycle is not uniform, but there is fluctuation.Diesel engine speed fluctuations have long been people pay attention, but the fuel injection, There are not many researchers who study the fluctuation of air intake and combustion process, and lack of connection with structure, usage, etc. In this paper, two instruments with high real-time and high sampling frequency are used in different loads, different working conditions and different fuel injection Under the structure, the influence of them on the circulation fluctuation was measured, and the mechanism of the fluctuation was tentatively explored.
