Abstract:
An exhaust system may include an exhaust line through which a combusted exhaust gas is exhausted outside, a nitrogen oxide purification catalyst that is mounted on the exhaust line and uses unburned fuel or hydrocarbon to reduce one part of the nitrogen oxide in the exhaust gas and diffuse the other part thereof to store therein, an injector that injects fuel into the exhaust line, a fuel cracking catalyst that is disposed between the injector and the nitrogen oxide purification catalyst to activate the additionally injected fuel from the injector through thermal decomposition so as to generate a reducing agent of high reactivity, and a control portion that controls the injector to additionally inject fuel in a predetermined condition such that the nitrogen oxide purification catalyst uses the activated reducing agent to detach and reduce the nitrogen oxide that is stored therein.
Abstract:
A system and a method for stabilization control may control position and direction of an object having first and second bodies connected to each other. The system may include an artificial vestibular apparatus for outputting a movement signal corresponding to movement of the first body and a rotation signal corresponding to rotation of the first body; a translating actuation unit connected between the first and second bodies and controlling position of the second body in response to the movement signal; and a rotating actuation unit connected between the first and second bodies and controlling rotation of the second body in response to the rotation signal. If the system and the method are applied to a vision system of a mobile robot, the vision system may obtain stabile image information even when the mobile robot is moving. Thus, it is possible to prevent any blurring from occurring at the image information.
Abstract:
A pressure adjusting valve for a vehicle fuel line includes a diaphragm disposed in a housing and dividing the interior of the housing into first and second compartments. A valve plate is provided in the second compartment and attached to the diaphragm. A return unit is provided in the second compartment. An elastic member provides an elastic force to the diaphragm toward the second compartment. An elastic force adjusting unit controls the elastic force of the elastic member.
