Regimes of near-stoichiometric hydrogen/air combustion under reciprocating engine conditions

1Introduction Hydrogen/air combustion is a problem both in respect of its fundamental science and in the use of hydrogen as a possible substitute for traditional hydrocarbon fuels.There is now a generally agreed approach to the use of hydrogen as an addition to traditional fuels(He et al.,2017)but the use of hydrogen as a main fuel has been studied much less because of the substantially unresolved problems for effective hydrogen production(Liu et al.,2020).It is worth noting that the use of hydrogen as a main fuel may be primarily applied not only for internal combustion engines needed for transport(Balat,2008),but also for those serving as drives for electrogenerators within stationary power stations(Balat,2008;Ivanov et al.,2018).
