Patent number: 11059522Abstract: A vehicle (1) comprises a passenger compartment (2) in which a front seat (32F), a rear seat (32R), and a floor (33) between the front seat (32F) and the rear seat (38R) are provided. A first group (S1) of batteries (3) is mounted under the front seat (32F), a second group (S2) of the batteries (3) is mounted under the floor (33), and a third group (S3) of the batteries (3) is mounted under a rear seat (32R). By setting a height (h2) of the second group (S2) of the batteries (3) to be lower than respective heights (h1, h3) of the first and third groups (S1, S3) of the batteries (3), a battery mounting capacity of the vehicle (1) can be increased without affecting the comfort of the passenger compartment (2).Type: GrantFiled: February 16, 2010Date of Patent: July 13, 2021Assignee: NISSAN MOTOR CO., LTD.Inventors: Makoto Iwasa, Hidetoshi Kadota, Tadayoshi Hashimura, Shinya Ogata, Satoshi Shigematsu

Patent number: 6182447Abstract: A front exhaust pipe is connected to a front engine block, and a rear exhaust pipe is connected to a rear engine block. The front exhaust pipe extends from the front engine block downward, and curves and extends rearward. The rear exhaust pipe includes an upstream portion extending downward from a rear portion of the engine and a downstream portion extending forward from a lower end of the upstream portion and curving rearward. Rear ends of the front and rear exhaust pipes are joined together and connected to a main exhaust pipe. The rear and front exhaust pipe have substantially the same length. Therefore, vibration due to a difference between natural frequencies of front and rear exhaust pipes is reduced, and sound vibration performance is enhanced. Further, a declination of output due to disorder of exhaust pulsation in the confluence portion of the front and rear exhaust pipes is avoided.Type: GrantFiled: December 28, 1998Date of Patent: February 6, 2001Assignee: Nissan Motor Co., Ltd.Inventors: Tadayoshi Hashimura, Naoki Uchida, Hiroki Takishima
