Problems solved by technology

[0003] The intake port and exhaust port of the engine are arranged on the cylinder head of the engine. In the prior art, the intake port is a common blank hole formed by casting. After the air flow passes through the throat of the intake port, it flows into the combustion chamber through the valve. However, since the air intake in the prior art is a common blank hole formed by casting, the airflow encounters greater resistance when passing through its throat position, which in turn affects the air intake of the engine

Embodiment Construction

[0015] The invention provides a cylinder head of an engine, which can effectively reduce the resistance of the air flow in the air intake passage, increase the intake air volume of the engine, and make the oil and gas mix more fully when the engine is working. The present invention also provides an engine comprising the above-mentioned cylinder head.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] Please refer to figure 1 , figure 1 Schematic diagram of the intake passage and the exhaust passage ...

Abstract

The invention discloses a cylinder cover of an engine. The cylinder cover is internally provided with an air inlet channel and an air outlet channel; a first spherical groove is formed at an air inlet throat opening of the air inlet channel; and a second spherical groove is formed at an air outlet throat opening of the air outlet channel. With the adoption of the arrangement, the cylinder cover of the engine can reduce the resistance borne by an air flow in the air inlet channel effectively, increases air input of the engine, and allows oil and air to be mixed more sufficiently when the engine works. The invention further provides the engine comprising the cylinder cover.

Description

technical field [0001] The invention relates to the technical field of engines, and more specifically relates to an engine and a cylinder head thereof. Background technique [0002] The engine is the heart of the car, and sufficient air intake can ensure adequate mixing of oil and gas, thereby improving engine power performance and reducing emissions. [0003] The intake port and exhaust port of the engine are arranged on the cylinder head of the engine. In the prior art, the intake port is a common blank hole formed by casting. After the air flow passes through the throat of the intake port, it flows into the combustion chamber through the valve. However, since the air intake in the prior art is a common blank hole formed by casting, the air flow encounters greater resistance when passing through its throat position, which in turn affects the air intake of the engine. [0004] Therefore, how to reduce the resistance of the air flow in the intake passage of the cylinder hea...
