Problems solved by technology

When the engine is under partial load conditions, when the intake valve 13 and the exhaust valve 14 are opened at the same time, the intake air enters the cylinder 15 from the intake port 11 through the intake valve 13. Due to the small intake pressure and low flow rate, Exhaust gas with different flow directions will flow back into the cylinder 15, resulting in excessive residual exhaust gas in the cylinder, insufficient scavenging, and deterioration of combustion, resulting in reduced power and increased fuel consumption of the engine under partial load conditions.

Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] Such as Figure 2-5 As shown, the embodiment of the present invention provides an engine, which includes a cylinder head, a driving part and a guide vane 21 . An intake port 22 and an exhaust port 23 are arranged on the cylinder head, an intake valve 24 is arranged at the end of the intake port 22 , and an exhaust valve 25 is arranged at the end of the exhaust port 23 . The driving part is installed on the outside of the cylinder head, and the driving part is connected with the deflector 21 to drive the movement of the deflector 21. The driving part can be specifically a driving cylinder. The deflector 21 is arranged in the intake passage 22, and the deflector 21 has a guide stroke and a return stroke under the action of the driving part,...

Abstract

The invention discloses an engine. The engine comprises a cylinder cover, a driving part mounted on the cylinder cover, and a flow deflector (21) connected with the driving part, wherein an air inlet passage (22) is arranged on the cylinder cover; an air inlet valve (24) is arranged at the tail end of the air inlet passage (22); the flow deflector (21) is positioned in the air inlet passage (22), and has a flow deflecting course and a return course under the effect of the driving part; the flow deflecting course points to the middle space of the air inlet passage (22) from the inner wall of the air inlet passage (22); the return course points to the inner wall of the air inlet passage (22) from the middle space of the air inlet passage (22). The air scavenging in a combustion chamber of the engine is sufficient, so that the power of the engine is improved, and the oil consumption of the engine is reduced. The invention further discloses an automobile.

Description

technical field [0001] The invention relates to the technical field of automobile structures, in particular to an engine. The invention also relates to a motor vehicle. Background technique [0002] The engine is one of the core parts of the car, and the cylinder head is one of the important parts of the engine. The cylinder head is used to support the cam mechanism of the engine, and together with the cylinder, it forms the combustion chamber. The structure of the cylinder head will affect the intake and exhaust efficiency, and at the same time, it will affect the mixing state of the mixture in the combustion chamber, thereby affecting the combustion efficiency and engine performance. [0003] The operating conditions of the engine can be divided into two operating conditions: partial load and full load according to different loads. figure 1 It shows the air flow of the engine under the partial load condition. The characteristics of the intake and exhaust under this parti...
