小型二冲程汽油机换气过程的数值模拟

Simulation of Exchange Processes Small-Sized Two-Stroke Gasoline Engine

通过对引进的ＭＫ１４程序进行改造，针对小型二冲程汽油机换气过程的特点，提出了相应的边界条件和计算模型，并编制了工作过程的模拟计算程序。通过计算与实验结果相对比，验证了计算程序良好的可靠性与实用性。

Aimed at the characteristics of exchange process in small-sized two-stroke gasoline engines, the imported program MK14 is imprved in this paper, Which presents suiable boundryconditions and caculation models,and a simulation program is worked out for working processes of two-stroke gasoline engines. The accuracy practicability of the program are verifiedby the accordance of calculating and experimenting results.
