Abstract
The utility model relates to a novel heat shield for an exhaust manifold, which comprises a shield body and thermal insulation materials. The shield body comprises an upper shield part and a lower shield part. The thermal insulation materials are positioned between the upper shield part and the lower shield part. The side edges of the upper shield part and the lower shield part are provided with a rivet hole respectively and are fixedly connected together through a rivet. The upper end of the upper shield part is provided with a reinforcing rib and an oxygen sensor hole. The side end of the upper shield part is provided with a screw mounting hole. The novel heat shield for the exhaust manifold is good in thermal insulation effect, low in manufacturing cost, simple and reliable in connection mode, and better in both size stability and structural stability. Meanwhile, since the action time of a three-way catalyst during the cold starting process is shortened, exhaust indexes during the cold staring process are lowered. In addition, the heat shield is low in manufacturing cost and convenient in application and popularization.
Description
Technical field
The utility model relates to a kind of novel exhaust manifold thermal shield, belongs to the automobile exhaust system technical field.
Background technique
At present, existing exhaust manifold thermal shield adopts the heat-insulating structure of multilayer mostly, simultaneously the filling multilayer thermal-protective material, the Placement of this structure is more complicated often, cost is higher, and because the quality of multilayer insulation material is inhomogeneous or the materials variances of intermediate thermal insulating layer, causes effect of heat insulation poor, set up higher, and structure stability must not get and effectively guarantee, and then causes the automobile exhaust amount to increase the weighting ring environment pollution.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of reasonable in design is provided, and easy for installation, good heat-insulation effect, is convenient to the novel exhaust manifold thermal shield of maintenance maintenance.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise cover body and thermal-protective material, described cover body is made up of upper outlet body and lower cover, described thermal-protective material is between upper outlet body and lower cover, described upper outlet body and lower cover side offer the riveting hole, be fixedly linked by rivet, described upper outlet body upper end is provided with stiffening rib and lambda sensor hole, and upper outlet body limit end offers screw mounting hole.
The utility model has the advantages that:
Have heat-blocking action preferably, low cost of manufacture, Placement is simple and reliable, make that dimensional stability and the structure stability of thermal shield are better, the action time of ternary catalyzing unit when having shortened cold machine simultaneously and starting, the exhaust index when having reduced cold machine and starting, low cost of manufacture is convenient to penetration and promotion.
