The calculations of ignition delay time of hydrogen-air mixture diluted silane based on our previously physical and mathematical models of ignition and combustion of silane/hydrogen/oxygen/nitrogen mixtures, which takes into account detailed kinetics were carried out. It was shown that low temperatures up to 2200K silane addition in hydrogen-air mixture leads to a monotonic decrease in ignition delay time. However, at the temperatures greater than 2200K there is the opposite effect: an addition of a small amount of silane (～20%) in a hydrogen-air mixture leads to a greater decreasing of the ignition delay time compared with mixtures with a large amount of silane (>20%).
