摘要： A dual fuel engine, which is designed to allow choosing between gas operation and diesel operation, with low emission of NOx ensured even during diesel operation, and which is capable of adjusting the compression ratio during the gas operation according to the operating state, so as to provide a quick start and an operation with high combustion efficiency throughout the load region, comprising a cylinder head that is provided with a compression ratio control valve, and a pre-combustion chamber unit having a pre-combustion chamber and an electromagnetic type fuel injection valve liquid fuel injection valve. The compression ratio control valve opens/closes a communication port connecting a main combustion chamber and an inlet port. In the gas operation, the valve opening period of the compression ratio control valve is adjusted according to the operating state, part of the mixed gas in the main combustion chamber is released to the inlet port to adjust the compression ratio, and the combustion gas is ignited for combustion by a pilot amount of liquid fuel from the electromagnetic type fuel injection valve. In the diesel operation, the compression ratio control valve is closed and the liquid fuel injected with a high compression ratio from the electromagnetic type fuel injection valve is burnt on the pre-combustion system.

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 T ave is compared with the exhaust temperature T( n ) of each cylinder, and it is determined whether the deviation ΔT n is greater or smaller than the set deviation T limit for that load factor. When the deviation ΔT n 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 ΔT n 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 52 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 unit (4) is fixed to a turning cylinder (8) which is turnable relative to a ship body. A pinion (12) of a drive shaft of a servo motor (3) is engaged with a turning ring (10) of the turning cylinder (8). The servo motor (3) is connected to a servo amplifier (2). A controller (1) and an operating wheel (16) on a bridge side and a control board (18) and a manual turn button (17) in a steering engine room are connected to the servo amplifier (2) via a changeover switch (19). A tracking transmitter (14) provided on the turning ring (10) is connected to the controller (1). A turning position command inputted from the operating wheel (16) causes the servo motor (3) to be driven. The actual turning position of the ship propulsion unit (4) is detected by the tracking transmitter (14), and servo control is performed to bring the deviation between the turning position specified by the turning position command and the actual turning position to 0. It is possible to switch control to the steering engine room and carry out manual control. Accurate turning position control can be realized for a turnable ship propulsion unit.
