摘要:
An exhaust structure of a forklift truck is provided to prevent vibration of an exhaust pipe from being transmitted to an exhaust tube without a complicated structure. An exhaust structure of a forklift truck includes a muffler(20), an exhaust pipe(25), and an exhaust tube(30). The muffler is connected to an engine to admit exhaust gas exhausted from the engine. The exhaust pipe guides the exhaust gas through the muffler outside a car body(10). The exhaust tube is installed outside the car body and guides gas exhausted from the exhaust pipe outside. An internal diameter of the exhaust tube is larger than an external diameter of the exhaust pipe so that an end of the exhaust pipe is surrounded by the exhaust tube.
摘要:
An aluminum titanate ceramic article having a predominant crystal phase of aluminum titanate and a material composition including aluminum, titanium, silica, an alkaline earth metal (e.g., at least one selected from the group of strontium, calcium, barium, or combinations), and a rare earth metal (e.g., at least one selected from the group consisting of yttrium, lanthanum, and combinations) and methods of making such aluminum titanate bodies are described. An oxide of yttrium metal or lanthanide metals is preferably used as a sintering aid in combination with the other compositional components to enable firing of the resulting green body at a lower heating temperature of less than 1500‹C, and more preferably between 1400‹- 1450‹C, with a preferable hold time of less than 8 hours, more preferably of 6 to 8 hours. ® KIPO & WIPO 2007

摘要:
An efficiently usable honeycomb catalyst, a denitration catalyst of a denitration device, and an exhaust gas denitration device capable of reducing the running cost of an exhaust gas denitration system by the denitration catalyst to approx. half. The honeycomb catalyst comprises gas flow passages for feeding treated gas from the inlet side to the outlet side thereof, performs treatment on the side walls of the gas flow passages, and has such a length that the flow of the treated gas fed in the gas flow passages is generally streamlined near the outlet side thereof.

PURPOSE: An isolator of a heat protector is provided to reduce noise and vibration produced from a vibrometer of an engine by improving structure of the isolator. CONSTITUTION: An isolator(30) of a heat protector(10) for isolation between an engine body and the heat protector is interposed in the outer periphery of a bolt(14) for fixing the heat protector to the engine body. The heat protector intercepts heat transfer of an exhaust system of an engine to the vicinity of the engine. A metal mesh body(40) formed in a net shape is interposed between an outer retainer(31) situated in a bolt hole(11) of the heat protector, and an inner retainer(35) fitted in the middle of the bolt.

PURPOSE: A catalyst converter of a vehicle is provided to automatically change the purifying performance and the discharge resistance according to the traveling state of the vehicle by using a characteristic by the size of cells of a catalyst carrier. CONSTITUTION: A catalyst converter of a vehicle comprises a converter housing(3) forming an inlet(1) to the engine side and an outlet(2) to the muffler side; a fixed catalyst carrier(5) fixed inside the converter housing; a rotating catalyst carrier(7) rotatably installed inside the converter housing; a rotating unit rotating the rotating catalyst carrier according to the operation state of an engine. The lattice-shaped section of the rotating catalyst carrier is opposite to the lattice-shaped section of the fixed catalyst carrier. The fixed catalyst carrier is installed to the outlet side of the converter housing and the rotating catalyst carrier is installed to the inlet side of the converter housing.
