  • Publication number: 20180252148
    Abstract: A coolant passage device 3 includes coolant intake pipes 11 and 12 that take in coolant from an engine, a delivery pipe 17 to a radiator communicating with the coolant intake pipes, and a delivery pipe 18 to the heater core branched from a central passage 16 connecting the coolant intake pipes with the delivery pipe to the radiator. A branch port 18a leading to the delivery pipe 18 to the heater core is opened in an upper portion in the central passage 16 in a state where the coolant passage device 3 is mounted to the engine, and the branch port 18a has a wall surface 21 surrounding the branch port and hanging down into the central passage 16. The wall surface 21 prevents bubbles contained in the coolant from entering the branch port 18a. And the coolant passage device consequently prevents coolant flow noise from occurring.

  • Patent number: 9695776
    Abstract: A cylinder block includes a first bank, a second bank, and a press-fitting portion. The first bank and the second bank are arranged in positions offset from each other in a cylinder arrangement direction. The press-fitting portion is provided straddling a first end surface of the first bank and a second end surface of the second bank. The press-fitting portion has a hole. The first end surface protrudes in a direction in which the press-fitting portion protrudes in the cylinder arrangement direction, with respect to the second end surface. A thickness of the press-fitting portion in a radial direction of the hole at a first portion that is connected to the first end surface is thinner than a thickness of the press-fitting portion in the radial direction of the hole at a second portion that is connected to the second end surface.

  • Patent number: 7568893
    Abstract: When an air pump is operated, a brush temperature increase rate stored in an ECU in relation to a discharge pressure of the air pump and a brush temperature is multiplied by a calculation cycle time, and the resultant value is cumulatively added. When the air pump is stopped, a brush temperature decrease rate stored in the ECU in relation to the brush temperature is multiplied by the calculation cycle time, and the resultant value is cumulatively added. Each of the cumulative values read from a map is added to and subtracted from an initial brush temperature value, respectively so as to estimate the brush temperature.
