    摘要: To provide an exhaust gas purification catalyst that is less likely to cause an increase in pressure loss, even a large amount of zeolite-based SCR catalyst is used to improve NOx purification capability. The exhaust gas purification catalyst includes a DPF provided with zeolite having a primary particle size equal to or less than 0.5 μm. In addition, it is preferable that 50% particle size of the zeolite measured by dynamic light scattering is equal to or less than 2.0 μm, and further, it is preferable that the 90% particle size of the zeolite is equal to or less than 2.5 μm.

    摘要: An oil separator includes: a spindle; a rotor rotable together with the spindle and having an inner peripheral space, the rotor configured to be rotated by introducing, into the inner peripheral space, separating oil and processing-target gas containing mist oil so that the mist oil is separated from the processing-target gas; a case having an internal space and an inlet hole communicating with the internal space, the internal space housing a separation chamber having the spindle and the rotor; and a lower partition wall member disposed in a lower end of the internal space and provided with a through hole penetrating a center of the lower partition wall member in an up-down direction, the spindle being inserted into the through hole.

    摘要: A heat exchanger includes: a stack formed by stacking a plurality of tubes through which gas flow; a tubular inner tank in which the stack is housed; and a tubular outer tank that is mounted on the outside of the inner tank so as to define an inner space between the outer tank and an outer peripheral surface of the inner tank. Each of both end portions of the tubes has a thickness greater than each of middle portions of the tubes. The both end portions of the tubes adjacent to each other in the stack are joined together so as to form a clearance between the middle portions of the adjacent tubes in the stack. Outer peripheries of both end portions of the stack are joined to an inner peripheral surface of the inner tank. An introduction hole for introducing a cooling medium is formed in the outer tank.

    摘要: In an oil separator that separates mist oil contained in target gas from the gas, the present disclosure is aimed to easily mount the oil separator to various targets and to increase its versatility. An oil separator according to the present disclosure includes: a nozzle that injects oil from an injection hole to rotate a spindle around an axis; a housing having a gas communicating portion and an oil communicating portion on its bottom; and a joint member that is removably mounted to the housing, and that includes a gas introducing portion and an oil discharge portion, the gas introducing portion introducing blow-by gas and transferring the gas to the gas communicating portion, the oil discharge portion receiving oil from the oil communicating portion and discharging the oil to outside.

    摘要: A lower partition wall having a through hole vertically penetrates the lower partition wall center. A spindle is inserted into the through hole. The top surface side of the lower partition wall includes a convex portion, a groove, and a drain hole. The convex portion is concentrically disposed at the through hole periphery. The groove extends, from an outer peripheral side of the convex portion, toward the through hole on an inner peripheral side. The drain hole is outside the convex portion, vertically penetrating the lower partition wall. The separated oil circles a top surface of the lower partition wall. The oil flowing to an inner peripheral side of the lower partition wall is guided to the groove and flows into the through hole. The oil flowing to an outer peripheral side of the lower partition wall flows into the drain hole.

    摘要: An oil separator that separates mist oil from processing-target gas containing mist liquid includes a plurality of separation disks. The plurality of separation disks rotate around an axis, and are stacked and spaced in an axial direction. The separation disk includes an inner peripheral part and an outer peripheral part. The inner peripheral part forms a surface of a frustum of a hypothetical cone or pyramid coaxial with the separation disk, and is inclined with respect to a radial direction toward one side in an axial direction. The outer peripheral part forms a surface of a frustum of a hypothetical cone or pyramid coaxial with the separation disk, and continuously extends outward from an outer peripheral edge of the inner peripheral part. The outer peripheral part is inclined with respect to the radial direction toward another side in the axial direction.
