Abstract: In a reactor for solid ammonium salt, a method of controlling the reactor, and a NOx emission purification system using solid ammonium salt and selective catalytic reduction, the reactor includes a first chamber and a second chamber. The first chamber has an exhaust and a first heating element. Solid ammonium salt is in the first chamber. The second chamber has a second heating element and is formed at a side of the first chamber. The first chamber is connected with the second chamber. Solid ammonium salt is in the second chamber. An amount of the solid ammonium salt in the second chamber is more than that in the first chamber, so that the first chamber is heated and cooled faster than the second chamber.

Abstract: There is provided an external inline LPG fuel pump, and more particularly, an external inline LPG fuel pump; in which bushings are installed at first and second shafts of a motor to be fixed inside a housing, a ball is completely coupled to an end of the first shaft to prevent the motor from being shaken due to the bushings, and another ball is inserted into an end of the second shaft to fix the motor, thereby preventing the durability of the fuel pump from deteriorating by wear of a bushing part, a pumping part and an inside of the housing even though an LPG fuel is introduced when the motor is driven, prolonging the life of the fuel pump and reducing the repair and exchange costs involved with the fuel pump; in which a case inside which the housing is positioned is formed and a partition is installed inside the case, thereby cooling the high-temperature LPG fuel discharged through an outlet of the housing to reduce heat load and improving the durability of a device receiving the LPG fuel transferred from th

Abstract: This invention relates to a scavenging shroud mechanism for improving scavenging of a 2-stroke engine, and more particularly to a scavenging shroud mechanism for improving scavenging of a 2-stroke engine which is constructed such that a scavenging shroud mechanism is provided to a scavenging valve whereby compressed air sucked into an interior of a combustion chamber makes a tumble phenomenon along with cylinder wall surface and thereby pushes out already burned burnt gas and simultaneously is capable of efficiently feeding new air so that efficient reverse loop scavenging system is made. The scavenging shroud mechanism has a baffle 2, shroud guide notch 3 and a shroud neck 4, and a fixed supporting pin 6 and a supporting guide 5 provided on the inner side of the intake manifold 9. A shroud guide notch 3 is provided in the baffle 2 so as to permit the scavenging shroud mechanism 1 to up and down-ward movement but not right and left rotational movement.
