Patent number: 9482143Abstract: A water pump is disposed so as to be mounted on a cylinder head cover of an engine. An electric motor is disposed continuously from the water pump. The water pump sends cooling water to a water jacket of a cylinder block via a cooling water pipe disposed so as pass in front of the cylinder head cover and a cylinder head. In an upper end portion of a radiator, an inlet through which the cooling water is led from the engine is disposed on the left and an outlet through which the cooling water is supplied to the water pump is disposed on the right. The inlet is connected to the cylinder block via a cooling water pipe, and the outlet is connected to the water pump via a cooling water pipe.Type: GrantFiled: October 13, 2014Date of Patent: November 1, 2016Assignee: SUZUKI MOTOR CORPORATIONInventor: Yoshisato Inayama

Patent number: 8752866Abstract: When an exhaust gas sensor is mounted to an exhaust pipe into which exhaust gas from an engine is introduced, an intermediate member is made to intervene between the exhaust gas sensor and a boss provided in an exhaust manifold, the intermediate member being fastened to the boss by bolts and the exhaust gas sensor being screwed into a screw hole formed in the intermediate member, so that a sensor portion at a front end of the exhaust gas sensor is inserted into the inside of the exhaust pipe. Though the screw hole formed in the intermediate member is to be exposed to high-temperature gas of the exhaust manifold, stainless steel, whose high-temperature strength is high, being used for the intermediate member, a female screw of the screw hole is hard to be softened and an occurrence of torque down can be suppressed.Type: GrantFiled: November 16, 2011Date of Patent: June 17, 2014Assignee: Suzuki Motor CorporationInventor: Yoshisato Inayama
