Cylinder cover integrated with exhaust manifold, engine and automobile

Abstract

The invention discloses a cylinder cover integrated with an exhaust manifold, an engine and an automobile. The cylinder cover integrated with the exhaust manifold comprises a cylinder cover body, wherein a first combustion chamber, a second combustion chamber, a third combustion chamber and a fourth combustion chamber are arranged on the cylinder cover body; two exhaust holes and two air inlet holes are formed in the inner wall of each of the four combustion chambers and surround the center of the inner wall of each of the four combustion chambers; a boss is arranged on the cylinder cover body; a first air outlet and a second air outlet are formed in the boss; the two exhaust holes in the first combustion chamber and the two exhaust holes in the fourth combustion chamber are connected withthe first air outlet through a first exhaust passage; the two exhaust holes in the second combustion chamber and the two exhaust holes in the third combustion chamber are connected with the second air outlet through a second exhaust passage; and the first air outlet and the second air outlet are connected with a double-flow-passage turbocharger respectively. By the cylinder cover integrated withthe exhaust manifold, the problems that the exhaust stroke is too long and a three-way catalyst is not heated easily in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a cylinder head with an integrated exhaust manifold, an engine and an automobile. Background technique [0002] With the rapid development of the automobile industry, automobiles have become one of the indispensable means of transportation for people to travel. Engines are one of the important parts of automobiles. The design direction has also changed accordingly. [0003] As the country's emission regulations are becoming more and more stringent, especially for the emission restrictions in the cold start phase, it is necessary to let the three-way catalytic converter reach the working temperature as soon as possible, so as to improve the conversion efficiency. [0004] The traditional engine cylinder head and exhaust manifold are designed independently of each other, the exhaust manifold and the cylinder head are connected by bolts, and the exhaust manifold and the cylinder...
