Abstract
BACKGROUND: The study results of influence of the Mg/MoO3 composite nanoadditive on the combustion process in the 4Ch10.5/12 diesel engine are given. It is shown that the heat output process in diesel engines divides into two phases: kinetic and diffusive combustion. The review of simulation methods for the heat output process in a diesel engine considering kinetic and diffusive combustion based on the I.I. Vibe’s method is presented. The review of methods of indicator diagram processing helping to obtain parameters of the Vibe’s heat output law for the two-phase combustion for the sake of following simulation and working process analysis is made. The heat output analysis of the 4Ch10.5/12 diesel engine indicator diagram processing using the Mg/MoO3 composite nanoadditive is made.
AIMS: Research of the influence of the Mg/MoO3 composite nanoadditive to fuel on the heat output process in a diesel engine.
METHODS: The 4Ch10.5/12 air-cooled diesel engine with factory-built fuel supply system was tested at the engine test rig. During the research, influence of the Mg/MoO3 composite nanoadditive to fuel on the heat output process was studied.
RESULTS: It is found that using the nanoadditive leads to decreasing hardness of combustion process, reduction of self-ignition time delay, increasing the maximal temperature of working body in a combustion chamber, reduction of amount of heat output at the kinetic combustion. Working body temperature increase and simultaneous maximal cycle pressure decrease testify the growth of pre-expansion degree. Parameters of diffusive combustion remain almost stable no matter of mass fraction of the nanoadditive in diesel fuel.
CONCLUSIONS: It was revealed that nanoparticles of the Mg/MoO3 additive serve as a homogenizer helping to destroy drops of the sprayed fuel and to intensify the evaporation process. Moreover, the nanoparticles serve as self-ignition centers at early stages of the combustion process.
