Abstract: A suspension structure for a power unit is configured to suspend a power unit including a motor, a transaxle, and a power control unit. In the suspension structure for a power unit, the transaxle is arranged in a substantially center portion in a vehicle width direction, the motor is arranged at a position on an upper side with respect to the transaxle, and on one side in the vehicle width direction, and the power control unit is arranged at a position on the upper side with respect to the transaxle, and on an opposite side of the motor. In the suspension structure for a power unit, the motor and the power control unit are suspended on a principal axis of inertia substantially parallel with an axis in the vehicle width direction.

Abstract: A freight vehicle has a loading space, on which freight is loaded, rearward of a vehicle cabin in which an occupant rides. The freight vehicle includes a fuel cell mounted below the vehicle cabin and functioning as an electric power source, a storage portion disposed between the vehicle cabin and the loading space, and a tank disposed in the storage portion and stores fuel gas that is supplied to the fuel cell, and a radiator installed in the storage portion and performs heat exchange between air and a coolant that is supplied to the fuel cell.

Abstract: This invention is an exhaust gas recirculation apparatus such that exhaust gas recirculation master piston (12) is activated and acts to open exhaust valve (4) on the same cylinder (1) by driving a slave piston (14), thus recirculating exhaust gas into combustion chamber (2) from exhaust port (5) as a result of the pressure difference, thereby lowering the combustion temperature within combustion chamber (2) on the next power stroke and working to reduce NOx. Moreover, by selectively maintaining and releasing oil pressure in two types of passages (13) and (31), it can also be used as a compression pressure-release engine brake.
