摘要：
The work is devoted to an experimental and design-theoretical analysis of combustion regimes of depleted compositions of gas mixtures based on hydrogen and syngas in the combustion chamber of a spark-ignition internal combustion engine. The analysis made points to the energy advantages of use of syngas compared to hydrogen. Here, on the one hand, it has been shown that the indicated efficiency is weakly dependent on the excess-hydrogen coefficient, which allows the conclusion on the expediency of utilization of depleted compositions as more environmentally safe ones. On the other, the existence of a certain concentration limit has been demonstrated below which a significant underburning of a fuel–air mixture, including that determined by the dynamics of the combustion front in the combustion chamber of the internal combustion engine, is observed.
