  • Patent number: 7849734
    Abstract: Test equipment of engine motoring for automatically conducting an engine test includes a conveying mechanism that carries in and carries out an engine to and from a test position, a fixing mechanism that fixes the engine carried in to the test position, a coupling mechanism that directly couples an electrical motor to the engine and can detect drive torque, an encoder that generates a pulse signal as an operating standard in synchronism with rotation of the electrical motor, a plurality of detection units driven to reciprocate so as to be connected to and disconnected from or approach and separate from the engine positioned at the test position and detect a plurality of operating state quantities, a control unit for various driving controls, and a judging unit for judging whether the engine is normal by comparing information obtained by the plurality of detection units with standard information obtained in advance.

  • Publication number: 20090025466
    Abstract: The test equipment of engine motoring of the present invention includes a conveying mechanism (30) that carries in and carries out an engine to and from a test position, a fixing mechanism (40) that fixes the engine carried in to the test position, a coupling mechanism (60) that directly couples an electrical motor (50) to the engine and can detect a drive torque, an encoder (70) that generates a pulse signal as an operating standard in synchronism with rotation of the electrical motor, a plurality of detection units (80 through 130) that are driven to reciprocate so as to be connected to and disconnected from or approach and separate from the engine positioned at the test position and detect a plurality of operating state quantities, a control means (200) for various driving controls, and a judging means (200) for judging whether the engine is normal by comparing information obtained by the plurality of detection units with standard information obtained in advance.

  • Patent number: 6886241
    Abstract: An automatic piston installation apparatus according to the present invention includes a block positioning mechanism for positioning a cylinder block in a working area separated from a conveying line by moving the cylinder block in vertical and horizontal directions and by rotating the cylinder block around the crankshaft, a piston positioning mechanism for positioning the piston at an insertion position by moving the piston to the working area, a piston inserting mechanism for inserting the piston into a cylinder bore from above in the vertical direction, a cap positioning mechanism for positioning the connecting-rod cap by moving the connecting-rod cap to a fastened position in the working area, and a fastening mechanism for fastening the connecting-rod cap from below in the vertical direction. Thereby, the piston can be installed in various engines, such as inline-type and V-type engines, automatically, with a high degree of accuracy, and reliably, and productivity can also be improved.
