Abstract:
PURPOSE: A nitrogen oxide absorbing-reducing catalyst, a method for manufacturing the same, and a system for purifying nitrogen oxide including the same are provided to improve the activity of the catalyst at low temperatures. CONSTITUTION: A nitrogen oxide absorbing-reducing catalyst includes a support, a nitrogen oxide absorbing element, and one or more noble metals. The support includes alkali metal and aluminum or alkali earth metal and aluminum. The nitrogen oxide absorbing element is alkali metal, alkali earth metal, or rear earth elements. The noble metals are selected from a group including Pt, Pd, Ru, Ag, Au, and Rh. A method for manufacturing a nitrogen oxide absorbing-reducing catalyst includes the following: the hydroxide of the alkali metal or the hydroxide of the alkali earth metal are dissolved with aluminum nitrate in an aqueous solution; the solution is stirred, dried, and fired to obtain the support; the support is impregnated with the alkali metal, the alkali earth metal, or rear earth element and one or more noble metals; and the impregnated product is dried and fired.

본 고안은 높이조절을 위한 시프트 레버 구조에 관한 것으로, 시프트 레버(10)를 2중으로 분리하고, 분리부분에 높이 조절구(11)를 결합시켜 상하를 연결하되, 높이 조절구(11)의 내주연 하측과 하측 시프트 레버(10)의 외주연 상측에 나사부(15)를 형성하여 결합시키고, 높이 조절구(11)의 상단에 삽입공(12)을 형성하여 상측 시프트 레버(10)의 하측을 삽입하고 시프트 레버(10)의 하단에 형성된 걸림턱(16)에 걸리게 하여 결합하며, 상하 시프트레버(10) 사이에 압축스프링(13) 삽입하여 구성한다. 따라서 운전자의 체형에 알맞게 시프트 레버의 높낮이를 조절할 수 있게 하여 운전자의 편의를 도모하고 주행 안전성을 지속적으로 유지시키는 효과가 있다.
Abstract:
A method for controlling a pulley of a continuous variable transmission is provided to improve calculation performance of a transmission control unit and removing a process for setting a new torque ratio. A target shifting ratio and a target torque ratio are determined from a set map table by detecting a vehicle speed and an opening/shutting state of a throttle(S101,S102,S103). A safety coefficient for preventing slip of a primary pulley and a secondary pulley is extracted according to the target shifting ratio and the target torque ratio(S104). A radius of the pulley is controlled by determining control pressure of the primary pulley and the secondary pulley according to the safety coefficient(S105-S108).
Abstract:
A structure for mounting a heat protector at an engine exhaust manifold is provided to improve the endurance of a coupling section of a heat protector by preventing vibration from being directly transferred from an exhaust manifold to the heat protector. A structure for mounting a heat protector at an engine exhaust manifold comprises elastic members(12,14) positioned at the inner and outer portions of a heat protector(4). The heat protector is fixed to a boss(6) that protrudes from an exhaust manifold. A column(24) is interposed between a fixing bolt(10) and the elastic members such that the elastic members is not in direct contact with the fixing bolt. A retainer(28) is interposed between a head section(26) of the fixing bolt and the column such that the elastic members maintain elastic force thereof. Each elastic member includes a spring made of a conical cylinder member.
Abstract:
An exhaust manifold structure is provided to improve endurance of an exhaust manifold by allowing the exhaust manifold to be uniformly heated or cooled when the exhaust manifold is repeatedly heated by exhaust gas or cooled by external air. An exhaust manifold structure comprises an exhaust manifold body(11), which has a hollow section therein and an opening at one side thereof, and a flange(12). The exhaust manifold body has two runner plates(10) arranged in the vertical direction and welded to each other. The flange is welded to the peripheral portion of the opening of the exhaust manifold body. The flange is formed with a plurality of bolt insertion holes such that the exhaust manifold body is coupled with a cylinder head of an engine through a bolt and a nut. Four runner pipes(13) are integrally attached to the flange such that exhaust gas of the engine is introduced into an exhaust manifold.
