Abstract

Hydrogen and oxygen fuel obtained from water electrolysis mainly contains H2 and O2, usually abbreviated to HHO. The compositional characteristics of HHO were analyzed by gas chromatography-mass spectrometry (GC-MS). The influence of HHO on the combustion process in the cylinder was discussed. The change law of the maximum combustion pressure and the variation of the crank angle were studied, and the nonlinear dynamic process of the combustion process was revealed. The research indicated that the cylinder pressure increased after mixing HHO and that the period of flame development and rapid combustion was shortened. With the increase in HHO content, the cycle-by-cycle variations were reduced, combustion stability improved, partial-burning and other abnormal combustion phenomena improved, the phase space trajectory distribution gradually intensified, and the engine combustion process of the cyclical variation increased.
