摘要： The exhaust gas purification device includes a substrate, a first catalyst layer, and a second catalyst layer. The substrate includes an upstream end and a downstream end. The first catalyst layer contains first catalyst particles and lies on the substrate across a first region extending between the upstream end and a first position. The first position is at a first distance from the upstream end toward the downstream end. The second catalyst layer contains second catalyst particles and lies on the first catalyst layer across the first region. The second catalyst layer is provided with pores. Pore connectivity of the second catalyst layer is 5% to 35%. A mean value of areas of the pores of the second catalyst layer in a cross-sectional backscattered electron image of the second catalyst layer may be 0.7 μm2 to 9.0 μm2.

摘要： An internal combustion engine includes an intake passage structure. The engine is configured such that a cylinder head is formed integrally with an intake manifold portion. A cylinder central axis is oriented parallel to an extending direction of an intake passage, when viewed in a side view. An injector is arranged such that it does not interfere with peripheral components, including the intake passage and a throttle body. The injector is disposed in the intake manifold portion such that a leading end thereof is oriented towards the intake valve of the cylinder head. The intake passage on the upstream side of an injector attachment position is offset from the injector in a width-direction of the internal combustion engine.

摘要： A direct current motor is disclosed. The motor includes a stator, a commutator, an armature core, and brushes. The stator has a yoke and magnetic poles. The magnetic poles are arranged at a predetermined pitch along a circumferential direction of the yoke. The number of the magnetic poles is represented by the expression: 2×P (P is an integer not less than 2). The commutator has segments that are arranged in a circumferential direction of the commutator. The number of the segments is represented by the expression: P×N (N is an odd number not less than 3). The armature core is rotatable integrally with the commutator and includes teeth provided by the number represented by the expression: 2×P×N. A coil is wound around the teeth by distributed winding. Each one of the brushes is pressed against and contacts the segments. Two of the segments that are electrically short-circuited by one of the brushes are connected to each other by at least two coils that are arranged at an interval corresponding to an integral multiple of the pitch (360°/(2×P)) of the magnetic poles.

摘要： A direct current motor is provided that includes an armature core, a commutator, coils, positive brushes, and negative brushes. The armature core includes a stator. The stator has magnets the number of which is represented by P (where P is an even number greater than or equal to six). The coils are wound about the teeth by duplex wave winding. Alternatively, the coils are wound about the teeth such that each pair of coils that are spaced apart by 180° are connected common ones of the segments. Each of the positive brushes and the negative brushes has an angular width WB, at which it slides on the segments. When the angular width of the arrangement pitch of the segments is represented by WP (WP=360°/the number of the segments), and the angular width of the clearance between each pair of circumferentially adjacent segments is represented by WU, the angular width WB is set to satisfy the expression: WB≦(4/P)×WP+WU.
