摘要： In the present invention, there is provided a cylinder head in which seat rings, against which are placed intake valves, are mounted respectively on a plurality of intake ports that communicate with a combustion chamber of an internal combustion engine, and, among the plurality of intake ports, an intake port on which is mounted an eccentric seat ring, with a center of an inner diameter of this eccentric seat ring being eccentric relative to a center of an outer diameter of this eccentric seat ring, is present together with an intake port on which is mounted a standard seat ring, with a center of an inner diameter of this standard seat ring matching a center of an outer diameter of this standard seat ring. As a result, a flow coefficient can be secured using the intake port on which the standard seat ring is mounted, and the swirl flow can be strengthened using the intake port on which the eccentric seat ring is mounted. Consequently, it is possible to obtain the two conflicting elements of a secure flow coefficient and a strengthened swirl flow.

摘要： The gas engine of the present invention has a pilot oil fuel valve, a pilot oil pump, and first and second pipes connected to a pilot oil main pipe, for each of a plurality of combustion chambers. An operating pilot oil tank and an ignition stimulant-added pilot oil tank are connected via a switching valve to a third pipe, connected to an end of the pilot oil main pipe. Before operating stops, the pilot oil is discharged by opening an exhaust valve, and thereafter, the switching valve is switched and pilot oil which the ignition stimulant has been added to is supplied into the pipe. Consequently, the pilot oil downstream from the main pipe is replaced with the pilot oil which the ignition stimulant has been added to. Therefore, at the time of the next activation, pilot oil which the ignition stimulant has been added to is sprayed from the fuel valve, and, as a result, misfire at the time of activation is reduced, and a highly reliable engine is obtained.

摘要： A gas turbine combustor includes a combustion cylinder, a premixing tube, and a pressure injection unit. Holes are formed in a peripheral wall of the premixing tube in a tangential direction. An inner wall is provided in the peripheral wall while having a gap therefrom. The compressed air in the gap forms a swirl flow. The compressed air and injected fuel supplied into the inner wall form straight flows each with a predetermined cross-section area in the inner wall under no influence of the swirl flow. They are combusted in the combustion cylinder via a protruding wall. The flame is stably retained at an appropriate position apart from the top portion of the combustion cylinder to improve durability without being excessively heated. This may prevent deterioration in durability of the combustion cylinder by the heat by retaining the flame at the appropriate position in the combustion cylinder.

摘要： The present invention has been realized in order to keep the cylinder exhaust temperature of a gas engine within a predetermined range, and thereby prevent the generation of misfire and knocking. In the present invention, in S1, when the number of rotations of the engine is greater than a predetermined number, in S2, the exhaust temperatures of the cylinders are sampled at predetermined intervals, in S3, an average of the exhaust temperatures is calculated, in S4, the load factor at that point is determined, in S5, the average exhaust temperature Tave is compared with the exhaust temperature T(n) of each cylinder, and it is determined whether the deviation ΔTn is greater or smaller than the set deviation Tlimit for that load factor. When the deviation ΔTn is smaller, the exhaust temperature is within the set deviation and there is no need to adjust the fuel spray period, and therefore the sequence returns to S2. When the deviation ΔTn is greater, in S6, it is determined whether to increase or reduce the opening period of the electronic fuel spray valve. When increasing the opening period, the sequence shifts to S7, and when reducing the opening period, the sequence shifts to S8. Then, in S9, if the engine exceeds the predetermined number of rotations, the processes of S2 to S6 are repeated; in S9, if the engine is below the predetermined number of rotations, the control operation ceases.

摘要： A ship propulsion device (1) is adapted to rotate a propeller (20) to propel a ship (2). In a case where the rotating speed of the propeller (20) is less than a predetermined rotating speed, a low-output sub-motor (M2) is controlled and rotationally driven by a small-capacity general-purpose inverter (24), and the rotational driving is transmitted to the propeller (20) so as to rotate the propeller. In that case, in a drive system of a main motor (M1), rotation is not transmitted to a slip clutch (23) or an input shaft (7) by cutting off an on-off clutch (8). In a case where the rotating speed of the propeller (20) becomes equal to or more than the predetermined rotating speed, a driving source is switched from the sub-motor (M2) to the main motor (M1) so as to couple the on-off clutch (8), and the rotating speed of the main motor (M1) is controlled by the slip clutch (23) and transmitted to the propeller (20) so as to rotate the propeller (20).

摘要： A gas turbine combustor includes a combustion cylinder and a premixing tube. A protruding wall of the tube has an inner diameter enlarging portion with a chamfer at an open end thereof. A swirl flow in the tube is guided outward along the chamfer, so that the cross-section area of a straight flow in the tube is expanded to have a lower flow velocity, and the distance between a flame in the cylinder and the enlarging portion is shortened. When using the fuel with high heat radiation upon combustion, the enlarging portion is replaced with the one having a smaller chamfer. The cross-section area of the straight flow is reduced to increase the flow velocity, and the lift distance becomes longer. Therefore, the damage to the combustion cylinder owing to the intensified heat radiation is prevented. The flame lift position retained in the cylinder is easily set and changed.
