The Period of Ignition Delay for Methane-Air Mixture with Hydrogen and Ethylene Additives

The article is devoted to estimating the intensifying efficiency of methane-air ignition by adding a small amount of hydrogen and/or ethylene. It presents features of the experimental determination of the ignition delay period for fuel-air mixtures using shock installation and methods of processing...
