Abstract
The utility model discloses an electric injection motorcycle air inlet pipe; the top of an air inlet pipe (10) is connected with a flange (5); two sides of the air inlet pipe (10) are connected with a left and a right air inlet manifolds (4, 6) to constitute a three-way device; lower ends of the left and the right air inlet manifolds are connected with air inlet flanges (1, 9); the utility model is characterized in that side bottom surfaces of the left and the right air inlet manifolds (4, 6) are respectively provided with a left and a right oil injection holes (2, 7); a left and a right lug bosses (3, 8) are respectively arranged between the oil injection holes and the parting surface A; the left air inlet flange (1) and the right air inlet flange (9) are respectively two non-concentric semicircles on the B surface. The utility model has simple structure, exact control of the throttle and equal air inlet quantity of the two cylinders, ensures the reliable operation of the electric injection system, and improves the working efficiency of the engine.
Description
(1). technical field
The utility model newly belongs to engine art, particularly is used for the two juxtaposed cylinders electronic fuel injection engine suction tude of motorcycle with electronic fuel injection system.
(2). background technique
What two juxtaposed cylinders electronic fuel injection engine gas handling system was adopted at present is the binodal air door body, and promptly two throttle bodies are connected in parallel, the aperture of throttle drag-line interlock control two closures.This method is owing to adopt two throttle bodies independently to control air inlet, is connected with spring between closure and the rotating shaft, so complex structure, and two throttle opening differences, particularly during return, two cylinder air inflows arranged side by side are unequal, cause engine power decline.
(3). summary of the invention
The purpose of this utility model provides a kind of two juxtaposed cylinders EFI suction tude.It is simple in structure, the closure precise control, and two cylinder air inflows equate, can guarantee the electric injection system reliably working, improve efficiency of engine.
For reaching above-mentioned purpose, the top adpting flange of the utility model suction tude, both sides connect left and right intake manifold and form a three-way device, the lower end of left and right intake manifold is connected with inlet flange, it is characterized in that: the side bottom surface of left and right intake manifold is respectively arranged with left and right nozzle opening, be respectively arranged with left and right boss between nozzle opening and mold joint A, left inlet flange and right inlet flange are respectively the semicircle of two decentraction on the B face.
Therefore the utility model only needs a closure control air inflow owing to be respectively arranged with left and right nozzle opening in the side bottom surface of left and right intake manifold, therefore simple in structure, and the closure precise control can guarantee the reliably working of electric injection system.
Below in conjunction with drawings and Examples the utility model is further specified:
(4). description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the rear view of Fig. 1;
Fig. 3 is a kind of embodiment of the present utility model.
(5). embodiment
Referring to Fig. 1, Fig. 2.The top adpting flange 5 of suction tude 10, both sides connect left and right intake manifold 4,6 and form a three-way device, the lower end of left and right intake manifold 4,6 is connected with inlet flange 1,9, angle between flange 5 and the left and right inlet flange 1,9 is 0 °～30 °, and the angle between flange 5 and the left and right inlet flange 1,9 is that 10 ° of left and right sides effects are better.The side bottom surface of left and right intake manifold 4,6 is respectively arranged with left and right nozzle opening 2,7, between nozzle opening and mold joint A, be respectively arranged with left and right boss 3,8, the angle of left and right nozzle opening 2,7 and left and right support boss 3,8 and mold joint A is 15 °～60 °, and its angle is that 30～35 ° of effects are better.Left side inlet flange 1 and right inlet flange 9 are respectively the semicircle of two decentraction on the B face.
Referring to Fig. 3.An oil sprayer 11 respectively is installed in nozzle opening 2,7, on support boss 3,8,, respectively oil sprayer is fixed with oily rail support 12 again with aluminum pipe 13 bed hedgehoppings; Then this suitable novel suction tude flange 1,9 is installed on the cylinder head, the throttle body of control air inflow is installed on total inlet flange 5.When engine operation, rotate Oil Switch, closure is opened, and air flows to total inlet pipe 10 by throttle body, and the separated into two parts left and right sides intake manifold 4,6 of flowing through drives the fuel oil that ejects from oil sprayer then, enters the cylinder head intake duct; After the atomizing fuel oil, enter combusted cylinder by intake valve control.
