Prechamber initiation of detonation in gaseous mixtures
A process of deflagration-to-detonation transition in propane-butane-oxygen and acetylene-oxygen mixtures, in an open channel with a circular cross section with a diameter of 3 mm, was investigated experimentally. Detonation initiation was carried out by burning the mixture in the prechamber connected to the channel. The prechamber was considered as an

Possible applications of prechambers in hydrogen internal combustion engines
The use of hydrogen as a fuel for an internal combustion engines has caused many problems for years, the most significant of which seems to be the excessive emission of nitrogen oxides and the tendency to knock combustion. In order to ensure better control of the combustion process in a internal combustion engine powered by hydrogen, it has been ...
