Structure, its design science, the problem of also solving electric injection system idle supplement while making bi-block engine air inlet more smooth.
To achieve these goals, technical scheme：A kind of bi-block engine inlet suction port structure, it includes connecting
The inlet suction port body being connected between air filter and engine throttle, idle speed step motor, it is characterised in that：The air inlet connecting
Head body one end has the first interface being connected with the air filter, and the inlet suction port body other end has and described first
Interface be connected and can the second interface being connected corresponding with the engine throttle, idle speed step motor, the 3rd interface and
4th interface, wherein, the second interface, the 3rd interface are corresponding to be connected with two choke valve aditus laryngis of the engine throttle
Connect, the 4th interface is connected with the air inlet aditus laryngis of the idle speed step motor.
Further, the second interface on the inlet suction port body, the 3rd interface are with the central shaft of the first interface
It is symmetrical set on the basis of perpendicular where line, and the central axis of the 4th interface is in the perpendicular.
Further, the 4th interface is by the angled elongation moulding of first interface inwall, and the 4th interface in
The first interface inwall forms inner passage port, and the inner passage port and the first interface inwall are in rounding off.
Further, have on the inlet suction port body outer wall some in reinforcement intersecting in length and breadth.
Further, it is provided with the port outer wall of the first interface, second interface, the 3rd interface, the 4th interface
Anchor ear neck.
Further, the engine throttle is double nip choke valve, and the idle speed step motor be integrated in it is described
On engine throttle.
Beneficial effects of the present invention：Design science, by by by air filter to engine throttle, idle speed step motor
The integration of inlet suction port structure assembly, can both meet the air supply requirement to engine twin-tub, also solve the problem that electric injection system idling is mended
The problem of gas, whole inlet suction port structure cause air inlet characteristics of compact layout, have saved assembly space, and cause bi-block engine air inlet
It is more smooth, it is very useful.
