Abstract

The special free piston movement of the linear hydrogen internal combustion engine results in a lower combustion reaction rate and an equal volume degree of heat release. In order to reduce the loss of combustion time and improve the efficiency of energy utilization, pilot lean combustion technology was tried in a linear hydrogen internal combustion engine. Based on mechatronics, the dynamics and kinematics simulation analysis and experimental study of valve train of linear hydrogen internal combustion engine are carried out in this paper. The feasibility of lean burn technology is verified by principle test, and then the combustion performance and operation characteristics of linear hydrogen fuel internal combustion engine are simulated by an iterative calculation method coupled with piston motion. Compared with the traditional hydrogen internal combustion engine, the combustion duration of linear hydrogen internal combustion engine is longer, the maximum combustion pressure and average temperature are smaller, which is conducive to nox emission control, but the combustion isovolumetric heat release is less, the afterburning is more serious, and the indicating efficiency is lower. This provides valuable reference for the performance evaluation and optimal design of valve train.
