[OBJECT] To prevent hunting without providing a bypass route in an engine with a denitration reactor installed upstream of a turbine. [MEANS] Providing a pressure gauge 7a to detect a scavenging pressure Ps within a scavenging trunk 6, a motor 8a to assist...

[OBJECT] To provide an exhaust gas emission purifying device in a more compact size, and to prevent a decrease in catalytic performance due to the adsorption of intermediates such as ammonium sulfate even if the fuel contains a large quantity of sulfur com...

An injection apparatus (6) includes a container (62), a liquid ammonia supply part (69) for supplying a predetermined amount of liquid ammonia into the container (62), a compression part (65) connected to the container (62) and for compressing a gas filled...

An exhaust gas exhausted from a combustion chamber (20) of a two-stroke engine (1) is fed to a turbine (51) of a supercharger (5). Part of the exhaust gas that has passed through the turbine (51) is extracted as an EGR gas by an exhaust gas recirculation p...

A two-stroke engine (1) includes a cylinder (2) having a scavenging port (23) and an exhaust port (24), a piston (3) provided in the cylinder (2), a first ejection part (61) for ejecting liquid ammonia into a combustion chamber (20), and a supercharger (5)...

Provided is an ammonia oxidation/decomposition catalyst which can decrease the reduction temperature of a support, which is required for the catalyst to have a property of being activated at room temperature, and also can render a property of being activat...

To eliminate a need for a reheating burner to heat an exhaust gas, and to eliminate a need for an evaporation tube which causes a loss of a flow path pressure. [MEANS] An exhaust gas emission purification device 1, provided with an exhaust chamber 5 which ...

An ammonia-engine system is capable of supplying an ammonia cracking catalyst with a temperature necessary to promote a reaction even during low load operation in which a temperature of an exhaust gas from an ammonia engine is lower than an operating tempe...
