Problems solved by technology

[0007] However, a problem with the partition 105 is that if the partition 105 is continuously exposed to hot exhaust gases, due to the limitations of the physical characteristics of the exhaust manifold made of aluminum and formed integrally with the cylinder head 100, the A rupture occurred at 105-1
[0008] In order to solve this problem, it is considered to form the water jacket 106 close to the partition, however, the problem is that in the current grinding tool structure, it is difficult to construct the water jacket to increase in length, and it is also considered to form the exhaust port close to the water jacket, however The problem is also that a 4-2 type exhaust structure cannot be formed due to structural limitations and the shape of the exhaust manifold
[0009] In addition to this, the thickness of the partition is increased compared to the prior art, thereby improving the durability of the partition, however in this case, the problem is that the cross-sectional area of ​​the exhaust port is reduced to increase the exhaust resistance

Abstract

An exhaust manifold for vehicles may include a partition provided between a first junction where at least two of runners of the exhaust manifold leading to a cylinder join and a second junction where remaining runners join.

Description

technical field [0001] The present invention relates to an exhaust manifold for a vehicle, and more particularly, the present invention relates to an exhaust manifold for a vehicle that prevents the exhaust gas in the exhaust manifold from being continuously exposed to hot exhaust gases. Crack occurs at the end portion of the mouth. Background technique [0002] Recently, the use of cylinder heads integrally formed with exhaust manifolds has been increasing to suit the downsizing design concept of gasoline turbochargers, and in particular, the cylinder heads are often used to improve fuel in high-speed high-load regions Consumption rate. [0003] In the cylinder head integrally formed with the exhaust manifold, the cylinder head is integrally formed with the exhaust manifold so that the temperature of the cooling water is increased through the exhaust manifold to increase the temperature of the combustion chamber, so it is different from the related art Ratio can use leane...
