Abstract:
An exhaust gas aftertreatment housing and an exhaust gas aftertreatment package. The exhaust gas aftertreatment housing (5) comprises a cone (6) and a heat preservation housing (7) mating with the cone (6). The cone (6) is provided with a first weld joint (613) and a second weld joint (614). The heat preservation housing (7) is provided with a first side edge (71) and a second side edge (72), wherein the first side edge (71) is provided with spacedly arranged: a first notch (711), a second notch (712), a third notch (713) and a fourth notch (714). When the cone (6) and the heat preservation housing (7) are mated at a first position, the first weld joint (613) corresponds to the first notch (711), and the second weld joint (614) corresponds to the third notch (713); and when the cone (6) and the heat preservation housing (7) are mated at a second position, the first weld joint (613) corresponds to the second notch (712), and the second weld joint (614) corresponds to the fourth notch (714). The multiple notches are provided, so that when the cone and the heat preservation housing are mated at the first position and the second position, the different notches are mated with the cone respectively, thus achieving the feasibility of multi-angle mating and improving diverse mounting modes.
