Abstract
The utility model relates to an inlet pipe of four-cylinder multiple electric control gasoline engine, comprising a harmonic resonance device of upper inlet pipe body and a lower connector of inlet pipe, wherein the upper harmonic resonance device is communicated with the lower connector; the harmonic resonance device of upper inlet pipe body comprises a resonant cavity and four exit branches of upper body, while the lower connector of inlet pipe comprises four exit branches of lower body and nozzle seats arranged on the exit branches of lower body. The utility model has the advantages of ensuring the charge efficiency of the electronic injection gasoline engine, improving the power performance by 10 to 15 percents, lowering the oil wear by 10 percents and ensuring that the exhaust emission can meet the requirements of environmental protection. The utility model is especially suitable for the inlet pipe used for transforming the four-cylinder carbureted gasoline engine with a capacity of 2.5 to 3 L into multiple electric control injection type gasoline engine.
Description
Technical field
The utility model relates to a kind of air inlet device on the combustion engine, further is meant a kind of four cylinder multiple spot electric control gasoline engine suction tude.
Background technique
Existing homemade 2.5～3 liters of carburetor type motor petrol motors; because environmental protection is to the requirement of exhaust emissions increasingly stringent; have to change into the employing electric control gasoline injection engine; but its suction tude is to transform on original suction tude and forms at present; so just, make the power performance (comprising power and moment of torsion) of petrol engine be difficult to guarantee; more can't improve, and oil consumption is higher, the exhaust emissions index also is difficult to get a desired effect.
Summary of the invention
The purpose of this utility model, be to influence the problem that petrol engine dynamic property can improve, oil consumption is higher and exhaust emissions exceeds standard, a kind of four cylinder multiple spot electric control gasoline engine suction tude that improve power performance, reduction oil consumption and the exhaust emissions of petrol engine are provided for what the suction tude that solves existing homemade four cylinder multiple spot electric control gasoline engines existed.
Solution of the present utility model is as follows.It is communicated be combined into by connecting body two-part under suction tude upper body resonance device and the suction tude, its suction tude upper body resonance device has the resonant cavity of a sealing, one end of resonant cavity offers the suction port that communicates with its inside, one side of resonant cavity is provided with four upper body arms that are connected with intra resonant cavity respectively, connecting body has four lower body arms that connect together under the suction tude, the suction port end of four lower body arms is communicated with the air outlet end of four upper body arms respectively and combines, and the lateral part by the air outlet on four lower body arms is equipped with the nozzle carrier that is connected with lower body arm inside, place respectively.
When the utility model with said structure uses on being installed to four cylinder multiple spot electric control gasoline engines, suction port on the resonant cavity of suction tude upper body resonance device is connected with petrolic throttle valve body, the air outlet end of four lower body arms of connecting body under its suction tude is connected with four inlet holes on the cylinder cap of petrol engine respectively, install nozzle on the nozzle carrier with four lower body arm afterbodys, the mouth mouth of four nozzles is connected with the firing chamber of four cylinders respectively.Since the intra resonant cavity total measurement (volume) near or greater than petrol engine swept volume (being commonly called as discharge capacity), therefore after importing air from the resonant cavity suction port, make motor in the course of the work, fluctuation reduces in the suction tude, and make the air inlet fluctuation produce regular resonance, improve engine power performance to increase the motor charging efficiency.Connecting body is the cylinder cap of four cylinders of connection and the intermediate section of suction tude upper body resonance device under the air inlet, the air that enters motor enters respectively in four cylinders by its four lower body arms, these four lower body arm branches are arranged, do not link to each other mutually, can prevent that so just each cylinder pressure wave from interfering with each other and avoiding to rob in the working procedure gas phenomenon.
Suction tude of the present utility model upper body resonance device can guarantee the charging efficiency of electronic injection gasoline engine, makes power performance improve 10～15%, and oil consumption descends 10%, and exhaust emissions reaches environmental requirement.This suction tude is specially adapted to the Inlet Manifold Design of 2.5～3 liter of four cylinder carburetor gasoline engine when changing multiple spot electronic fuel injection formula petrol engine into.
Description of drawings
Fig. 1 and Fig. 2 are respectively a kind of concrete structure plan view of the utility model and left view;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
Referring to Fig. 1 to Fig. 3.The utility model is communicated be combined into by connecting body 2 two-part under suction tude upper body resonance device 1 and the suction tude, its suction tude upper body resonance device 1 has the resonant cavity 11 of a sealing, one end of resonant cavity 11 offers the suction port 111 that is connected with its inside, one side of resonant cavity 11 is provided with four upper body arms 12 that are connected with resonant cavity 11 inside respectively, connecting body 2 has four lower body arms 21 that connect together under the suction tude, the suction port end of four lower body arms 21 is communicated with by bolt 3 with the air outlet end of four upper body arms 12 respectively and combines, for preventing leak gas available intermediate washer or sealer sealing, the lateral part by the air outlet end on four lower body arms 21 is equipped with the nozzle carrier 211 that is connected with lower body arm 21 inside, place respectively.
Referring to Fig. 2, four upper body arms of suction tude upper body resonance device 1 12 adopt circular pipes, and its diameter changes from small to big from bottom to top, and to reduce intake resistance, avoid squaring up in its turning, to prevent the air-flow turn sharp.
Referring to Fig. 3, the sectional area of four of connecting body 2 lower body arms 21 should be less than cylinder head suction port sectional area under the suction tude, the centerline length of four arms 21 unanimity of should trying one's best, so that each cylinder intake resistance is identical, improve each cylinder working uniformity, four arms 21 can progressively carry out the transition to circle by square, also can keep square.
