Abstract
Flame glow unit for heating the combustion air for a combustion device, especially an internal combustion engine. A flame glow plug, which is placed in the air duct of the combustion device, is supplied by a control device with current and fuel, and forms an ignitable air-fuel mixture together with the in-flowing air, which is ignited by a heating element provided in the flame glow plug. The resulting flame heats the air in the air duct. The air current in the air duct is measured by an air current measuring device and the control device controls the fuel supply of the flame glow plug in response to the measurements which the control device receives from the air current measuring device.
