摘要： The purpose of the present invention is to provide an exhaust purifier which suppresses unnecessary consumption of pressurization air so as to improve a removal rate of dust. An exhaust purifier for removing particulate matter adhered to a NOx catalyst by injecting pressurized air using an air injection nozzle into a housing of a catalyst reactor in which the NOx catalyst serving as a catalyst is positioned, wherein an injection valve of a soot blower supplying pressurized air into the housing of the catalyst reactor is opened and closed based on an exhaust gas flow rate so as to inject the pressurized air.

摘要： An exhaust gas purification system includes, as an exhaust gas path of an engine to be mounted in a ship, a main path which is in communication with outside, a bypass path which branches off from a halfway portion of the main path, and a combined casing with which both the main path and the bypass path are in communication. A selective catalyst reduction device is accommodated in the combined casing at a location close to the main path. A path-switching member which switches exhaust gas moving direction is placed in a branched portion between the main path and the bypass path. A reducing agent injection body is placed in the main path between the path-switching member and the combined casing.

摘要： An engine device which can simplify a supply air cooling structure of an engine as well as simplifying a support structure of a first supercharger and a second supercharger. In an engine device in which the first supercharger and the second supercharger are arranged in series in an exhaust gas discharge channel of the engine, the first supercharger and the second supercharger are arranged in one side surface of the engine, the second supercharger is arranged so as to be close to the one side surface of the engine, and the first supercharger is arranged so as to be away from the one side surface of the engine.

摘要： A supercharged engine includes an emission control device configured to add a reduction agent to exhaust gas from an engine main body to reduce nitrogen oxide in the exhaust gas by a catalyst, the supercharged engine including an air release valve configured to discharge a part of supplied air to be supplied from a supercharger to the engine main body through an air feed pipe to the outside of the air feed pipe, and a control device configured to control temperature of the exhaust gas by operating the air release valve and adjusting an amount of supply of the supplied air to be supplied from the supercharger to the engine main body.

摘要： The object of the present invention is to provide a compact engine. An engine has a two-stage turbocharger provided with a high-pressure turbocharger and a low-pressure turbocharger. The high-pressure turbocharger and the low-pressure turbocharger are separately disposed on the gear case side and the flywheel side in along direction of a main body respectively. An intake pipe and an exhaust pipe connecting the high-pressure turbocharger with the low-pressure turbocharger are separately and respectively disposed on right side and left side in a transverse direction of the main body.

摘要： An exhaust gas purifier including a casing, SCR catalysts (comprising a first SCR catalyst and a second SCR catalyst), a first backflow prevention plate, and a second backflow prevention plate. In the casing, at least a part of the catalyst passage and at least a part of the bypass passage are formed. The SCR catalysts are disposed in the catalyst passage and selectively reduce NOx included in an exhaust gas flowing in the catalyst passage. The first backflow prevention plate prevents or reduces a backflow of an exhaust gas from a second exhaust passage to the catalyst passage.

摘要： An exhaust gas purification device for a ship including: a main path communicated with outside and a bypass path branching off from a midway portion of the main path, each of the paths serving as an exhaust gas path of an engine to be mounted in the ship. A partition plate, by which the main and bypass paths are partitioned from the upstream side to the downstream side in an exhaust gas traveling direction, extends along the exhaust gas traveling direction. The partition plate has a downstream end extended through between an exhaust gas outflow port of the purification casing and an exhaust gas outlet of the main path, and the downstream end is formed with an opening to serve as a reverse-flow prevention plate.

摘要： An engine device in which exhaust pipes and an intake pipe can be mounted highly rigidly by using an upper face corner of a cylinder block in an engine, and a support structure of the exhaust pipes and the intake pipe can be simplified. In an engine device in which a first supercharger and a second supercharger are disposed in series on an exhaust gas discharge path of an engine, the engine device has a structure in which the first supercharger and the second supercharger are disposed to be divided on opposed side faces of the engine, and an upper side exhaust pipe between the engine and the first supercharger, a lower side exhaust pipe between the first supercharger and the second supercharger, and an intake pipe between the first supercharger and the second supercharger extend to be substantially flush with one another at a head-cover disposed-height of an upper face of the engine.
