Abstract: A vehicle body lower part structure includes: a side frame that connects a side sill to a battery pack that is arranged below a floor portion; and a battery frame that supports a battery within the battery pack. A first joint flange that is joined to a case bottom portion of the side frame is arranged such that a second joint flange that is joined to the case bottom portion of the battery frame overlaps an upper side in an upward-downward direction of the first joint flange.

Abstract: A vehicle body lower part structure includes: a side frame that connects a battery pack which is arranged below a floor panel of a vehicle to a side sill which is provided at a further outer position in a vehicle width direction than the battery pack; a lower cross member that is provided within the battery pack, is arranged between batteries, and extends in the vehicle width direction; and a connection portion that is provided within the battery pack and connects the lower cross member to the floor panel. The connection portion is provided at a further outer position in the vehicle width direction than the batteries.

Abstract: An ammonia decomposition system includes a decomposition unit and a controller. The decomposition unit decomposes ammonia. The controller controls the decomposition rate of ammonia in the decomposition unit.

Abstract: This oxidation catalyst for diesel engines is divided into an upstream-side catalyst layer and a downstream-side inner catalyst layer in the flow direction of the exhaust gas, and a downstream-side outer catalyst layer is additionally formed so as to cover the surface of the downstream-side inner catalyst layer. The upstream-side catalyst layer and the downstream-side inner catalyst layer contain Pd, and the downstream-side outer catalyst layer contains Pt. The amounts of Pt and Pd contained in the upstream-side catalyst layer and the amounts of Pt and Pd contained in the downstream-side inner catalyst layer are constantly set to certain values, while the amount of Pt contained in the downstream-side outer catalyst layer is set to a value which enables the oxidation efficiency to be at a predetermined value or higher.
