  • Publication number: 20150308077
    Abstract: A motor grader includes a fuel tank, a vehicle body frame, a left-side mount part, a right-side mount part, a rear-side mount part and a reducing agent tank. The left-side mount part and the right-side mount part are respectively disposed on a left lateral frame and a right lateral frame while being disposed on both sides of the fuel tank in a vehicle width direction, and fix the fuel tank to the vehicle body frame. The rear-side mount part is disposed on the left lateral frame in the vehicle width direction while being disposed rearward of the fuel tank, and fixes the fuel tank to the vehicle body frame. The reducing agent tank is disposed rearward of and adjacently to the fuel tank while being disposed on the right lateral frame side, and accumulates a reducing agent for processing an exhaust gas from an engine.

  • Patent number: 9151014
    Abstract: A work vehicle includes an engine, a selective catalytic reduction apparatus, a fuel tank, and a reducing agent tank. The selective catalytic reduction apparatus treats exhaust from the engine. The fuel tank includes a fuel tank body retaining fuel and a fuel supply port which supplies fuel to the fuel tank body. The reducing agent tank includes a reducing agent tank body retaining a reducing agent used in the selective catalytic reduction apparatus and a reducing agent supply port which supplies the reducing agent to the reducing agent tank body. The fuel supply port protrudes from the fuel tank body toward a first direction left or right with respect to a center axis line in the front and back direction of the vehicle. The reducing agent supply port protrudes from the reducing agent tank body toward a second direction opposite to the first direction.

  • Patent number: 8997468
    Abstract: A radiator is arranged behind an engine, a selective catalytic reduction apparatus, and a connecting pipe. A partition wall partitions first and second accommodation spaces. The engine, the selective catalytic reduction apparatus, and the connecting pipe are arranged in the first space. The radiator is arranged in the second space. A reducing agent tank is arranged behind the partition wall. A reducing ejection apparatus attached to the pipe ejects reducing agent into the pipe. A reducing agent hose connects the tank and the apparatus. The hose has a boundary portion positioned at a boundary between the first and second spaces. A height position of the boundary portion is between top and bottom sections of the connecting pipe. The boundary portion and the reducing agent ejection apparatus are arranged on a left or right side of a center line extending in a front and back direction of the partition wall.

  • Publication number: 20140311132
    Abstract: A motor grader includes an engine, a power transmission apparatus, a selective catalytic reduction apparatus, a fuel tank and a reducing agent tank. The power transmission apparatus is configured to transmit power from the engine. The selective catalytic reduction apparatus is configured to process exhaust from the engine. The fuel tank is configured to retain fuel. The reducing agent tank is configured to retain a reducing agent. The fuel tank is arranged so as to at least partially overlap with the engine in a planar view. The fuel tank is arranged between the power transmission apparatus and the reducing agent tank in a vehicle front to back direction.

  • Publication number: 20050063670
    Abstract: There is provided a content recording and reproducing apparatus including: a recording and reproducing portion which records and reproduces content data; an operating section which has keys allowing a user to input instructions for recording and reproducing of content data and for skipping during reproducing the content data; and a control portion that controls recording and reproducing of the content data in the recording and reproducing portion based upon instructions from the operating section. The control section executes a second skipping based on a second skip instruction that is inputted within a predetermined time from a time at which the recording and reproducing portion re-starts reproduction of the content data after a first skipping based on a first skip instruction.

  • Publication number: 20020002619
    Abstract: In a computer system connected to a network, direct access from the computer network side to a computer is inhibited to prevent illegal data reading or rewriting, data destruction or the like. A first storage unit 106, a data recording unit 102 and a recording medium carrier 105 are connected to a first computer 101. A data reproducing unit 104 is connected to a second computer 103. The first computer 101 controls the data recording unit 102 to record data stored in the first storage unit 106 into a recording medium. Then, the first computer 101 controls the recording medium carrier 105 to carry the recording medium 110 from the data recording unit 102 to the data reproducing unit 104. The second computer 103 controls the data reproducing unit 104 to reproduce the data recorded in the recording medium 110, and then transmits the reproduced data through the Internet 109.
