Abstract
The utility model relates to the field of air inlet/exhaust system of a diesel engine, in particular to an exhaust manifold provided with a booster flange, which comprises an exhaust manifold main pipe and a booster flange, wherein the booster flange is fixed on the exhaust manifold main pipe, the transition part between the booster flange and the exhaust manifold main pipe is a connecting part, and the wall thickness of the connecting part is 5.2 to 7.8 millimeters. By adopting the structure, the exhaust manifold can well solve the problem that the part close to the booster flange is cracked easily as the wall thickness of the connecting part is increased; and the thickness of the connecting part is partially increased, thus avoiding waste of material caused by increase of the whole wall thickness, reducing the cost of products, also reducing the self-weight of the diesel engine, and improving the performance of the diesel engine.
Description
Technical field
The present invention relates to diesel engine air inlet system and exhaust system field, relate in particular to the gas exhaust manifold product specification of band pressurized machine flange.
Background technique
Wear pressurized machine on the gas exhaust manifold, be widely used in the modern diesel engines air inlet system and exhaust system.The gas exhaust manifold of modern diesel engines is selected heat resisting cast iron usually for use, tube wall is generally 3.2 to 4.8mm, owing to be subjected to the influence of pulse exhaust, and when in use reaching the diesel engine bench test, stressed concentrating easily produces cracking defect near the gas exhaust manifold pressurized machine flange.The whole thickened wall that generally adopts is to the method for 6mm at present, though can well solve problem easy to crack, but the thickness in order to increase local intensity to integral body increases, both increased product cost, cause waste, also increased the diesel engine deadweight, aspects such as the oil consumption of diesel engine and self performance have been produced harmful effect.
Summary of the invention
The purpose of this utility model is at top described problem, and a kind of gas exhaust manifold of novel band pressurized machine flange is provided, and can well eliminate the defective of gas exhaust manifold cracking, can reduce product cost again, alleviates the diesel engine deadweight.
The utility model is achieved by the following technical programs:
A kind of gas exhaust manifold with the pressurized machine flange comprises that gas exhaust manifold is responsible for, the pressurized machine flange, and the pressurized machine flange is fixed on gas exhaust manifold and is responsible for, and carrying out the transition to the part that gas exhaust manifold is responsible for from the pressurized machine flange is joint, and the wall thickness of joint is 5.2 to 7.8mm.
Further, the wall thickness of described joint is 5.8 to 6.5mm.
Optimum efficiency is: the wall thickness of described joint (3) is 6mm.
After adopting structure of the present utility model, owing to increased the wall thickness of joint, can be good at solving near the problem easy to crack of gas exhaust manifold pressurized machine flange, and owing to just the joint part is thickened, avoided the problem of the waste of material of whole thickened wall generation, reduce the cost of product, also alleviated the deadweight of diesel engine, improved the performance of diesel engine.
