- a uniflow scavenging two-cycle engine that is also used as a marine engine has a scavenging port at one end in the stroke direction of a piston in a cylinder and an exhaust port at the other end. Then, when the active gas is sucked into the combustion chamber from the scavenging port during the intake (supply) stroke, the exhaust gas generated by the combustion action is exhausted by being pushed out of the exhaust port by the sucked active gas.

- the scavenging port 118 is a hole penetrating from the inner peripheral surface (the inner peripheral surface of the cylinder liner 110 b) on the lower end side of the cylinder 110 to the outer peripheral surface, and a plurality of scavenging ports 118 are provided over the entire periphery of the cylinder 110.
- the scavenging port 118 sucks the active gas into the cylinder 110 according to the sliding motion of the piston 112.
- This active gas contains an oxidizing agent such as oxygen and ozone, or a mixture thereof (for example, air).
- an active gas for example, air
- a blower not shown
- the compressed and cooled active gas is rectified by the rectifying plate 132 disposed in the scavenging reservoir 120, and then the moisture is removed by the drain separator 134.
- the scavenging chamber 122 communicates with the scavenging reservoir 120 and surrounds one end side (the lower side in FIG. 1) of the piston 112 in the cylinder 110 to compress, cool, and remove moisture.
- the activated gas is introduced.
- the scavenging port 118 is provided in a portion of the cylinder 110 (cylinder liner 110b) located in the scavenging chamber 122, and uses a differential pressure between the scavenging chamber 122 and the cylinder 110 according to the sliding operation of the piston 112. Then, the active gas is sucked into the cylinder 110 from the scavenging chamber 122. The active gas sucked into the cylinder 110 is guided to the combustion chamber 124 by the piston 112.

- one fuel pipe 136 through which fuel gas is guided to each scavenging port 118 extends in the stroke direction of the piston 112.
- the fuel injection port 126 is an opening formed on the side surface of the fuel pipe 136 toward the adjacent fuel pipe 136 side.
- An annular pipe 138 is disposed on the exhaust port 114 side (the upper side in FIG. 1) of the fuel pipe 136.
- the annular pipe 138 is a pipe that annularly surrounds the radially outer side of the cylinder 110 in the circumferential direction of the cylinder 110 and communicates with the fuel pipe 136.
- the fuel gas is guided to the annular pipe 138 from the fuel tank 140 in which the fuel gas is stored.
- the fuel injection port 126 injects the fuel gas supplied from the fuel tank 140 via the annular pipe 138 into the active gas sucked into the scavenging port 118.
- the fuel gas merges with the flow of the active gas, is sucked into the cylinder 110 from the scavenging port 118 together with the active gas, and is guided to the combustion chamber 124.
- the fuel injection port 126 is formed toward the adjacent fuel pipe 136 .

- a pilot injection valve 142 is provided in the cylinder head 110a.
- An appropriate amount of fuel oil is injected from pilot injection valve 142 at a desired point in the engine cycle.
- This fuel oil is vaporized by the heat of the combustion chamber 124 formed inside the cylinder 110 surrounded by the cylinder head 110a, the cylinder liner 110b, and the piston 112, and becomes fuel gas.
- the fuel gas vaporized from the fuel oil ignites spontaneously and burns in a short time, and the temperature of the combustion chamber 124 is extremely increased.
- the piston 112 reciprocates mainly by the expansion pressure due to the combustion of fuel gas.
- the fuel gas is generated, for example, by gasifying LNG (liquefied natural gas).
- LNG liquefied natural gas
- the fuel gas is not limited to LNG, and for example, gasified LPG (liquefied petroleum gas), light oil, heavy oil, or the like can be applied.
- LPG liquefied petroleum gas
- the fuel injection valve 128 is provided upstream of the fuel pipe 136 and the annular pipe 138 in the fuel supply path 144 that communicates from the fuel tank 140 to the fuel injection port 126.
- the fuel injection valve 128 opens and closes the fuel supply path 144 and controls fuel gas injection from the fuel injection port 126.
- FIG. 3 is a view for explaining the fuel injection valve 128, and shows a schematic cross section of the fuel injection valve 128.
- the fuel injection valve 128 is, for example, a hydraulic on-off valve, and when hydraulic oil is press-fitted into the hydraulic chamber 128 a, as shown in FIG. However, against the biasing force of the spring 128c, it moves to the left in FIG. 3 and closes.
- the valve body 128b moves to the right in FIG. 3 by the urging force of the spring 128c and opens. I speak.
- the distal end portion 128d of the fuel injection valve 128 communicates with the annular pipe 138, and in the state shown in FIG. 3A, the flow path from the fuel tank 140 to the fuel injection port 126 is blocked. Further, in the state shown in FIG. 3B, the flow path from the fuel tank 140 to the fuel injection port 126 communicates.
- the fuel injection valve 128 when the fuel injection valve 128 is disposed at a position communicating with the scavenging chamber 122 or the scavenging chamber 122 filled with the compressed active gas, for example, when the uniflow scavenging two-cycle engine 100 is stopped, the fuel injection valve 128 is used. When the fuel gas leaks from the fuel gas, the fuel gas flows into the compressed active gas.
- the fuel injection valve 128 is provided in an isolation space 146 isolated from the scavenging chamber 122 as shown in FIG.
- the isolation space 146 is isolated by the scavenging chamber 122 and the partition wall 148. That is, the isolation space 146 is also isolated from the scavenging reservoir 120 that communicates with the scavenging chamber 122.
- the isolation space 146 is a space isolated from the space filled with the compressed active gas.
- tip end portion 128d of the fuel injection valve 128 is inserted into a through hole 148a provided in the partition wall 148, and the gap between the through hole 148a and the tip end portion 128d is closed.
- the compressed active gas filling the scavenging chamber 122 hardly flows into the isolation space 146. Therefore, it is possible to avoid leakage of the fuel gas into the compressed active gas.
- a gas detection pipe 150a of the gas detection sensor 150 is disposed in the isolation space 146.
- the gas detection sensor 150 determines whether or not fuel gas is contained in the gas flowing in from the tip of the gas detection tube 150a, and detects leakage of the fuel gas. Since the active gas does not flow into the isolation space 146, the gas flow is less than that in the scavenging chamber 122. Therefore, when the fuel gas leaks into the isolation space 146, even if it is a small amount of leakage, early detection is possible without reducing the concentration of the fuel gas due to the gas flow.
- the isolation space 146 has a substantially sealed structure, and there is almost no inflow of outside air. Therefore, when fuel gas leaks into the isolation space 146, the concentration of the fuel gas does not decrease due to outside air, and further early detection is possible.
- the gas detection sensor 150 is not an essential structure for this indication.
- the isolation space 146 has a sealed structure.
- the isolation space 146 does not have a sealed structure, and outside air may flow into the isolation space 146.
- the present disclosure can be used for a uniflow scavenging two-cycle engine in which fuel gas is supplied into a cylinder when the fuel injection valve is opened.
