Abstract
The utility model discloses a motorcycle secondary air supply device, which mainly comprises an air inlet pipe, a negative pressure pipe, a secondary air combined valve, a heat-resisting pipe and a gas supply pipe, wherein an air inlet pipe is connected to an air cleaner; the negative pressure pipe is connected to a joint of a carburetor; the secondary air combined valve is arranged on the bottom of a fuel tank and locked on a frame; the heat-resisting pipe is connected to the secondary air combined valve and the gas supply pipe which is connected to an engine cylinder end. The utility model has the advantages of high efficiency and beautiful appearance of the whole motorcycle.
Description
Technical field
The utility model relates to the technical field of riding type car secondary air-supply device.
Background technique
Usually, the secondary air air feeder of riding type car, mainly comprise suction tude, negative pressure pipe, secondary air combination brake switch and proporting, heat-resistant tube and air supply pipe, wherein, suction tude is connected on the air-strainer, and the negative pressure pipe is connected on the joint of Carburetor, and the secondary air combination brake switch and proporting places fuel tank the place ahead, heat-resistant tube connects secondary air combination brake switch and proporting and air supply pipe, and air supply pipe is connected on the engine cylinder head.Like this, fresh air is sucked in the secondary air combination brake switch and proporting, fresh air is imported in the cylinder head,, thereby reduce content of harmful gas such as CO, HC in the tail gas with the tail gas of high temperature secondary response again through air supply pipe by suction tude.
But the detailed secondary air air feeder of seeing said structure is not difficult to find that there are these deficiencies in it: because the secondary air combination brake switch and proporting is positioned at fuel tank the place ahead, away from cylinder head, so effect is low; And, because outside the secondary air combination brake switch and proporting is exposed to, so outside the air supply pipe that is attached thereto etc. also was exposed to, each line arrangement had some setbacks, and directly influences the specious of car load.
The model utility content
The purpose of this utility model is to provide a kind of riding type car secondary air-supply device, and it has the effect height, guarantees the specious advantage of car load.
For reaching above-mentioned purpose, solution of the present utility model is:
The riding type car secondary air-supply device, mainly comprise suction tude, negative pressure pipe, secondary air combination brake switch and proporting, heat-resistant tube and air supply pipe, wherein, suction tude is connected on the air-strainer, the negative pressure pipe is connected on the joint of Carburetor, the secondary air combination brake switch and proporting places fuel tank bottom and lock to pay on vehicle frame, and heat-resistant tube connects secondary air combination brake switch and proporting and air supply pipe, and air supply pipe is connected on the engine cylinder head.
Above-mentioned secondary air combination brake switch and proporting places fuel tank bottom and lock to pay on support, and the support lock is paid on vehicle frame.
After adopting said structure, the utility model is owing to place the fuel tank bottom with the secondary air combination brake switch and proporting, promptly be positioned at the engine cylinder head lid directly over, so, the secondary air combination brake switch and proporting is very near from cylinder head, and distance makes the effect of secondary air-supply device improve greatly less than 20cm between the two.And distance is nearer between secondary air combination brake switch and proporting and each parts, makes each line arrangement more smooth and easy, and the secondary air combination brake switch and proporting major part that is positioned at the fuel tank bottom is again covered by fuel tank, and each pipeline is also covered, so, guarantee that car load is specious.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the utility model is installed in the position view on the vehicle frame;
Fig. 3 is that the utility model is installed in the position view on the car load.
Specific embodiment
See also shown in Figure 1ly, the riding type car secondary air-supply device that the utility model discloses mainly comprises suction tude 6, negative pressure pipe 7, secondary air combination brake switch and proporting 3, heat-resistant tube 8 and air supply pipe 9.
Cooperate shown in Fig. 2,3, suction tude 6 is connected on the air-strainer 11.
Negative pressure pipe 7 is connected on the joint 12 of Carburetor 5.
Secondary air combination brake switch and proporting 3 places fuel tank 4 bottoms, be positioned at directly over the cylinder-head cover 14, and lock is paid on vehicle frame 2.Shown in Figure 1 is that secondary air combination brake switch and proporting 3 locks are paid on support 10, and support 10 locks are paid on vehicle frame 2.
Heat-resistant tube 8 connects secondary air combination brake switch and proporting 3 and air supply pipe 9.
During work, fresh air is sucked in the secondary air combination brake switch and proporting 3 by suction tude 6, in air supply pipe 9 input cylinder heads 15, with the tail gas of high temperature secondary response again, thereby reduces content of harmful gas such as CO, HC in the tail gas.
The utility model is owing to pay secondary air combination brake switch and proporting 3 lock from the very near position of cylinder head 15, distance is less than 20cm between the two, so, can make the effect of secondary air-supply device improve greatly, and order connects between secondary air combination brake switch and proporting 3 and other each parts apart from nearer, so make that each line arrangement is more smooth and easy, again, secondary air combination brake switch and proporting 3 major parts that are positioned at fuel tank 4 bottoms are covered by fuel tank 4, and each pipeline is also covered, so, guarantee that car load is specious.
Claims (2)
1, riding type car secondary air-supply device, mainly comprise suction tude, negative pressure pipe, secondary air combination brake switch and proporting, heat-resistant tube and air supply pipe, it is characterized in that: suction tude is connected on the air-strainer, the negative pressure pipe is connected on the joint of Carburetor, the secondary air combination brake switch and proporting places fuel tank bottom and lock to pay on vehicle frame, heat-resistant tube connects secondary air combination brake switch and proporting and air supply pipe, and air supply pipe is connected on the engine cylinder head.
