Abstract
An engineering machinery used diesel engine cylinder cap comprises a cylinder cap body made by casting, an inlet duct and an exhaust duct arranged in the cylinder cap body; an inlet port and a rectangular exhaust port are arranged on the surface of the cylinder cap body; and at the middle of the exhaust duct, an inwards contracting mouth is arranged. The utility model adopts the Europe I type special inlet duct used in existing engineering machinery diesel engine as the inlet duct; the Europe II type exhaust duct used in existing diesel as the exhaust duct, accordingly reduces the exhaust pollution of engineering machinery used diesel engine, meets the Europe II effluent standard while reducing oil consumption.
Description
Technical field
The utility model relates to the cylinder head of a kind of cylinder cover for diesel engine, particularly a kind of industrial diesel engine.
Background technique
The high-horsepower diesel engine that present engineering machinery is used as engineering machinery steyr diesel engine, adopts Europe I emission standard for many years always, and the inlet and outlet road of its cylinder head is the special-purpose inlet and outlet of Europe I type road, and the oil consumption height pollutes heavy.Along with the raising of China to environmental requirement, the road road vehicle satisfies Europe II emission standard gradually, and industrial diesel engine still can not satisfy Europe II emission standard, if the cylinder head of road vehicle Europe, road II type diesel engine is used for industrial diesel engine, then can improve oil consumption, reduce its usability.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of cylinder head that not only can reduce exhaust emission but also can reduce the industrial diesel engine of oil consumption is provided.
The utility model industrial diesel engine cylinder head, comprise the cylinder lid that casting is made, be provided with intake duct and air outlet flue in the cylinder lid, the cylinder head surface is provided with suction port and relief opening, its structural feature is at the middle part of air outlet flue the closing in of contracting in to be arranged, relief opening be shaped as rectangle.
Intake duct of the present utility model still adopts the special-purpose intake duct of existing industrial diesel engine cylinder head Europe I type, and the actual cylinder head air outlet flue that has adopted existing Europe II type diesel engine of air outlet flue, thereby make industrial diesel engine reduce exhaust emission, Europe II emission standard can be satisfied, oil consumption can be reduced again.
