Abstract
The utility model relates to a gas-way structure of 2.0L petrol-engine, comprising a gas inlet way and a gas outlet way. The control ratio of the areas of the outlet and the inlet of the gas inlet way is 1.07, and the control ratio of the areas of the outlet and the inlet of the gas outlet way is 1.16. The gas-way structure acquired by the adoption of the area ratio of the inlet and the outlet of the gas way can better fit the request of the performance index of the engine. Therefore, the gas-way structure has simple design and high quality.
Description
Technical field
The utility model belongs to the technology of gasoline engine field, is specifically related to the air passage structure design of 2.0L petrol engine.
Background technique
The rationality of the cylinder cap air flue design of petrol engine, the channel shape of accurate gas port area control, smoothness, to organizing enough air inflows, producing desirable gas flow mode is very important, be directly connected to the good charging efficiency of motor, following process is followed in conventional cylinder cap air flue design: default engine performance index, calculate inlet and outlet road flow area, preliminary moulding air flue, the steady state test platform test optimization of last air flue, after finishing, mate repeatedly again with distribution device, inlet and exhaust system, obtain the air passage structure that needs at last.The shortcoming that this air passage structure exists is: need multi-parameter to optimize simultaneously, designing quality is not high, and the design cycle is long.
Summary of the invention
The utility model is at the deficiency of the air passage structure design existence of existing petrol engine, and purpose is to provide a kind of air passage structure of 2.0L petrol engine, by determining the import and discharge area ratio of air flue, obtains high-quality cylinder cap air flue, simplicity of design, quality height.
The technical solution of the utility model is as follows:
2.0L the air passage structure of petrol engine includes intake duct and air outlet flue, wherein the intake duct outlet is 1.07 with the area control ratio of import, and the air outlet flue outlet is 1.16 with the area control ratio of import.Adopt the above-mentioned air flue import and the area of outlet to compare the air passage structure of acquisition, can meet the performance index requirement of motor well, thus this air passage structure simplicity of design, the quality height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: S1: intake duct inlet-duct area S2: the first intake duct discharge area S3: the second intake duct discharge area.
S4: the first air outlet flue inlet-duct area S5: the second air outlet flue inlet-duct area S6: air outlet flue discharge area.
Embodiment
Referring to Fig. 1, the air passage structure of this 2.0L petrol engine includes intake duct 1 and air outlet flue 2, wherein the control ratio of first, second intake duct discharge area S2 and S3 and intake duct inlet-duct area S1 is 1.07, and the control ratio of air outlet flue discharge area S6 and first, second air outlet flue inlet-duct area S4, S5 is 1.16.For example: for the 2.0L motor of 4 valves, its intake duct inlet-duct area is 1300mm
2, its discharge area just is so: 1300*1.07/2=695.5mm
