For the purpose of preventing a decompression passageway in a two-cycle engine from being blocked by carbon soot, facilitating manufacture of a two-cycle engine having decompression structure and eliminating reduction of output power of the two-cycle engine caused by the decompression structure, a known two-cycle engine includes a scavenging passageway formed along an inner wall of a cylinder. The scavenging passageway is directed in the axial direction of the cylinder and communicates with a crank case of the engine. A decompression groove extends in the axial direction of the cylinder on the upstream side of a cylinder cooling airflow at a top end portion of the scavenging passageway. The width and depth of the decompression groove are either varied along the axial direction of the groove so as to be narrowed towards a tip end thereof directed toward a plug, or are provided with a narrowed portion of venturi shape.

Decompression device in a two-cycle engine

An apparatus for air-pulverizing high-temperature molten slag by blowing air at high speed through a nozzle into a flow of molten slag that is falling from an inclined container by the intermediary of a turndish. A heat detector is provided for detecting the quantity of heat in the flow of molten slag after being air-pulverized by the high speed air flow, and a feedback control device which is responsive to a detection signal issued from the detector is provided for calculating a desirable inclination angle of the container or the turndish and transmitting a control signal obtained as a result of the calculation to a controller for controlling the inclination of the container or turndish thereby stabilizing the air-pulverizing of the high-temperature molten slag.
