Detailed Description
The integrated exhaust manifold type four-cylinder machine cylinder cover cooling water jacket of the present invention will be further described below with reference to specific embodiments, so as to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 1 to 3, the integrated exhaust manifold type four-cylinder engine cylinder head cooling water jacket of the present embodiment has a first cylinder exhaust throat 91, a second cylinder exhaust throat 92, a third cylinder exhaust throat 93 and a fourth cylinder exhaust throat 94 integrated therein. The cooling water jackets include a main water jacket 1, an exhaust-side upper water jacket 3, and an exhaust-side lower water jacket 8 that are disposed in the direction of the first to fourth cylinder exhaust throats. And the front end of the four-cylinder engine cylinder cover is provided with an upper water port 11, and the upper water port 11 is communicated with the front end of the main water jacket 1. A first air inlet side water jacket 21, a second air inlet side water jacket 22, a third air inlet side water jacket 23 and a fourth air inlet side water jacket 24 are sequentially arranged from the front end to the rear end of the air inlet side of the four-cylinder engine cylinder cover, the water inlet ends of the first air inlet side water jacket to the fourth air inlet side water jacket are communicated with the main water jacket 1, the water outlet ends of the first air inlet side water jacket to the third air inlet side water jacket are communicated with the main water jacket 1, and the water outlet end of the fourth air inlet side water jacket 24 is communicated with the water outlet 12. The rear end of the main water jacket 1 is isolated from the water outlet 12 through a water outlet partition 5. An exhaust side partition 4 is arranged between the exhaust side upper water jacket 3 and the exhaust throat openings of the first cylinder to the third cylinder, and the exhaust side upper water jacket 3 is communicated with the rear end of the main water jacket 1. The exhaust side lower water jacket 8 is positioned below the exhaust side upper water jacket 3, the exhaust side lower water jacket 8 is communicated with the exhaust side upper water jacket 3 through an exhaust side longitudinal water jacket 7, and the exhaust side lower water jacket 8 is communicated with the water outlet 12. An exhaust throat partition 10 is arranged between the fourth cylinder exhaust throat 94 and the third cylinder exhaust throat 93 to prevent or reduce water backflow at the rear end of the main water jacket 1.
In the cooling water jacket of the present embodiment, the cooling liquid in the water jacket 1 is supplied from the cylinder head front end water supply port, and the cooling water jacket of the present embodiment is designed with two cooling water paths for cooling the intake side and the exhaust side, respectively. One is shown as an air inlet side cooling water path (as shown in figure 4), and cooling water flows through the air inlet side water jacket and then flows out of the water jacket through a water outlet 6; and the other is cooling for the exhaust side separately (as shown in figure 5), after cooling by the cylinder cover body, the cooling liquid flows through the exhaust side upper water jacket 3 from the exhaust side of the fourth cylinder, then is guided to the exhaust side lower water jacket 8 through the exhaust side longitudinal water jacket 7, and finally flows out of the cylinder cover through the exhaust side and then is merged with the intake side cooling liquid through the water outlet. In order to guide the direction of water flow at the exhaust side, three water jacket partitions are designed, namely an exhaust side partition 4, a water outlet partition 5 and a fourth cylinder exhaust throat partition 10.
By adopting the cooling water jacket, hot water in the exhaust manifold cooling water jacket is conveyed to the heat exchanger under the action of the water pump through hot water circulation, so that warm air can be obtained more quickly, and the heat circulation of the engine and the preheating of the engine room are improved. Compared with the water jacket in the prior art, the oil consumption of the engine can be reduced and the emission of the engine can be reduced under the working conditions of high load and nearly full load. And moreover, by reasonably distributing water flow of the water jacket, cooling water flow at the exhaust side is effectively improved, the cooling effect at the exhaust side is enhanced, the exhaust temperature is reduced, the performance of the engine is improved, and the emission of the engine is reduced.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
