Embodiment Construction

[0019] exist figure 1 with 2 In the structure shown, the intake port is an integral two-intake valve high-position tangential intake port, which has an intake port body 1, a valve guide boss 2 and an airway throat part 3, and the combustion chamber matched with it Chamber 4 is a sloping roof combustion chamber. The inlet 1a of the air inlet has a chamfer of 1×30°, which is formed by casting; the boss 2 of the valve guide is outside the main body 1 of the air inlet. The airway throat-to-throat ratio is 3. This part is formed by machining, and the angle γ between the two curved surfaces adjacent to the airway throat body 1 and the airway throat 2 in the tangential direction is 100°. The centerline 1b of the air inlet is basically a straight line when viewed from the side projection of the air inlet body (that is, the projection on the side view), and the straightness is less than 1mm. The cross-sectional shape of the air inlet body 1 is elliptical. Line 1b changes gently, and...

Abstract

The invention relates to a petrol engine air inlet path which is an integral high-order tangential air inlet path with two air inlet ports. A combustion chamber in cooperation with the air inlet path is a combustion chamber with a pitched roof; the outer side of the air inlet path body is provided with the valve conduit boss of the air inlet path. The invention is characterized in that the included angle gamma between the tangential direction of two curved surfaces, which are adjacent to an air path throat position, and the air path body is 60-150 degrees; the included angle beta between the air inlet path central line and the air inlet door central line of the air inlet path body is 30-60 degrees; the included angle alpha between the air inlet path central line of the air inlet path bodyand the exhausting side plane of the combustion chamber ranges from negative 10 degrees to 15 degrees. The above structure can ensure higher tumbling intensity and flow coefficient of the invention and realizes overall consideration of the tumbling intensity and flow coefficient of the petrol engine air inlet path.

Description

technical field [0001] The invention relates to the technical field of gasoline engines. Background technique [0002] Due to energy shortages and increasing environmental pollution, automobile engines need to maximize and utilize the energy of every drop of fuel and reduce the number of harmful emissions as much as possible. Among the many factors affecting the fuel consumption rate and harmful emissions, the combustion of fuel is the decisive factor, and the combustion is closely related to the movement of the airflow and the organization of the mixed gas, so the air passage of the automobile engine, especially the intake passage Energy saving and emission reduction of automobiles is very important. [0003] For the design of gasoline engine intake port, we pay special attention to the two indicators of flow coefficient and tumble intensity, and hope to obtain the largest possible flow coefficient and tumble intensity, but there are always contradictions between these two...
