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. |
