摘要： The present invention provides an exhaust gas purification catalyst with excellent warm-up characteristics, which can quickly exhibit effective catalytic activity even when exhaust gas in a relatively low temperature range is introduced. In the exhaust gas purification catalyst disclosed herein, a catalyst support portion provided on the base material includes: a catalyst coat portion having a carrier made of inorganic compound particles and at least one catalyst metal in a supported state on the carrier; and a catalyst metal direct support portion having at least one catalyst metal in a directly supported state on the base material without the carrier, the catalyst metal direct support portion is provided in at least an upstream region of a predetermined length from an upstream end in an exhaust gas passage, and the catalyst coat portion is not provided in the upstream region in the exhaust gas passage and is provided only in a downstream region downstream of the upstream region.

摘要： A ship comprising: a hull; a fuel ammonia tank which is provided in the hull and which stores fuel ammonia; a fuel supply line which is connected to the fuel ammonia tank; a combustion device into which the fuel ammonia is introduced from the fuel ammonia tank through the fuel supply line; an inert gas supply device which pumps inert gas into at least the combustion device through the fuel supply line; an ammonia recovery tank into which ammonia remaining in the combustion device is introduced together with the inert gas that has been pumped into the combustion device; a denitration device into which exhaust gas that is generated by combustion in the combustion device is introduced; and an ammonia introduction line which connects the ammonia recovery tank and the denitration device and which introduces, as a reduction agent, the fuel ammonia in the ammonia recovery tank into the denitration device.

摘要： A catalytic converter (26) is provided with: an inlet-side diffuser part (51); an outlet-side diffuser part (52); a case (53) including an upstream-side cylindrical part (61) and a downstream-side cylindrical part (62); an inner liner (54) provided in the upstream-side cylindrical part (61); a first catalyst (55) retained inside the inner liner (54); and a second catalyst (56) retained inside the downstream-side cylindrical part (62). An end face (56b) of the second catalyst (56) faces a peripheral surface of the inner liner (54). An annular flow path (64) is provided between the upstream-side cylindrical part (61) and the inner liner (54), and the first catalyst (55) is insulated from heat by the annular flow path (64). A part of exhaust flows into the second catalyst (56) via the annular flow path (64).

摘要： An engine 100 is provided with an engine body 1, a crankshaft 10, a cooling fan 6, an exhaust manifold 42, a supercharger 24, an ATD 43 that purifies exhaust gas, and a second exhaust pipe 52. When the height direction of the engine 100 is defined as a first direction, the crankshaft 10 extends in a second direction vertical to the first direction. The cooling fan 6 is disposed on one side of the engine body 1 in the second direction. The supercharger 24 is driven by the exhaust gas from the exhaust manifold 42. The second exhaust pipe 52 connects the supercharger 24 and the ATD 43. The ATD 43 is disposed in an attitude in which the longitudinal direction thereof is parallel to the second direction. The second exhaust pipe 52 is connected to the cooling fan 6 side of the ATD 43 in the second direction. The second exhaust pipe 52 is disposed so as to pass laterally with respect to the exhaust manifold 42 and below the supercharger 24.
