Abstract
The utility model relates to internal-combustion engines, in particular to a diesel engine exhaust pipe. The diesel engine exhaust pipe comprises an exhaust main pipe and exhaust branch pipes, wherein the exhaust main pipe and the exhaust branch pipes have an integrally molded structure and are connected to form an L shape; the exhaust branch pipes are arranged in parallel and have the hexagonal cross sections; and square through holes are formed in the exhaust branch pipes. The service life of the exhaust pipe is prolonged, the replacement cost is reduced, and the diesel engine exhaust pipe is high in plasticity and difficult to break off.
Description
Technical field
The utility model relates to internal-combustion engine, especially a kind of Diesel Engine Exhaust Pipe.
Background technique
Diesel Engine Exhaust Pipe is one of main accessory of diesel engine; Welding after the traditional exhaust pipe generally adopts cast iron or body steel plate to stretch, the one of which end is welded with flange again, and its medium cast iron outlet pipe fragility is big; Frangible; The inner surface of trachea grains of sand are difficult to cleaning, the wearing and tearing of acceleration components, the working life of shortening product.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency in the existing technology, a kind of good toughness is provided, the outlet pipe of long service life.
The utility model solves the technological scheme that its technical problem adopted: a kind of Diesel Engine Exhaust Pipe; Have exhaust manifold and exhaust branch pipe; Described exhaust manifold and the exhaust branch pipe structure that is formed in one, exhaust manifold and exhaust branch pipe be connected to form " L " font, exhaust branch pipe is arranged side by side; The cross section of exhaust branch pipe is a Hexagon, offers foursquare through hole on the exhaust branch pipe.
Further, described exhaust branch pipe has 4 at least.
The beneficial effect of the utility model is: increase the working life of outlet pipe, subdued renewal cost, plasticity is good, not frangible.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. exhaust manifolds, 2. exhaust branch pipe among the figure.
Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of Diesel Engine Exhaust Pipe as shown in Figure 1, a kind of Diesel Engine Exhaust Pipe has exhaust manifold 1 and exhaust branch pipe 2; Exhaust manifold 1 and exhaust branch pipe 2 structure that is formed in one; Exhaust manifold 1 and exhaust branch pipe 2 be connected to form " L " font, exhaust branch pipe 2 is arranged side by side, the cross section of exhaust branch pipe 2 is a Hexagon; Offer foursquare through hole on the exhaust branch pipe 2, exhaust branch pipe 2 has 4 at least.
Above-mentioned mode of execution is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
