Abstract
The nozzle in the cylinder head is supplied with solid particulate fuel, e.g. powdered coal, via a dosing wheel while a hollow slider in the nozzle blocks a supply of compressed air. After dosing, the hollow slider is moved into a position to block further entry of the particulate fuel while opening the nozzle to the compressed air supply. The fuel is then blasted out of the discharge openings of the nozzle into the combustion chamber of a cylinder.
