The accompanying drawing explanation
Fig. 1 is that motorcycle fuel injection system of the present utility model is applied to the schematic diagram on motorcycle.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.
Refer to Fig. 1, the utility model embodiment provides a kind of motorcycle, comprises motorcycle fuel injection system 100.Be appreciated that motorcycle also comprises the General Constructions such as vehicle frame and wheel, because described General Construction does not relate to the utility model content, so this paper will be not described in detail.
Motorcycle fuel injection system 100 comprises a motor 10, an outlet pipe 20 and a non-heating type oxygen sensors 30.Motor 10 is provided with a relief opening 12, and relief opening 12 is communicated with outlet pipe 20.
Due to the certain temperature conditions of non-heating type oxygen sensors 30 needs of work, to only have when the temperature of outlet pipe 20 is greater than 250 ℃, non-heating type oxygen sensors 30 is induction tail gas air fuel ratio situation accurately.Simultaneously, excess Temperature can cause non-heating type oxygen sensors 30 to be damaged, therefore the operating temperature range of non-heating type oxygen sensors 30 is chosen to be 250～850 ℃, and preferably to be located at outlet pipe 20 its temperature when motor 10 work be arbitrary position of locating between 250～850 ℃ to non-heating type oxygen sensors 30.。
During 100 work of motorcycle fuel injection system, tail gas flows out through outlet pipe 20 from the relief opening 12 of motor 10, and non-heating type oxygen sensors 30 heats to improve the sensing degree of accuracy of tail gas air fuel ratio by described high-temperature tail gas.Because the local temperature of outlet pipe 20 can be far and more lower with the distance of distance relief opening 12, therefore there is the motorcycle fuel injection system 100 of the motor 10 of different displacements, its non-heating type oxygen sensors 30 is also different apart from the position of relief opening 12.For example:
When the discharge capacity of motor 10 is less than 100cc, the temperature of relief opening 12 is 300～750 ℃, and now non-heating type oxygen sensors 30 preferably is located at the position of contiguous this relief opening 12 on outlet pipe 20.
When the discharge capacity of motor 10 is 100～200cc, the temperature of relief opening 12 is 450～870 ℃, and the temperature apart from relief opening 1210cm position on outlet pipe 20 is 350～700 ℃.Therefore, now non-heating type oxygen sensors 30 preferably is located on outlet pipe 20 position apart from this relief opening 1210cm.
When the discharge capacity of motor 10 is greater than 200cc, the temperature of relief opening 12 is 450～880 ℃, and the temperature apart from relief opening 1225cm position on outlet pipe 20 is 350～780 ℃.Therefore, now non-heating type oxygen sensors 30 preferably is located on outlet pipe 20 position apart from this relief opening 1225cm.
For preventing that the interior condensed water of outlet pipe 20 from dropping on non-heating type oxygen sensors 30, center line and the angle between ground that outlet pipe 20 is provided with non-heating type oxygen sensors 30 places should be greater than 70 °, preferably 90 ° of wherein said angles.Simultaneously, the mounting point of non-heating type oxygen sensors 30 can not be the position that outlet pipe 20 is minimum apart from ground.
In above-mentioned motorcycle fuel injection system 100, non-heating type oxygen sensors 30 is located on the position that outlet pipe 20 has applicable temperature, make without can guarantee equally the sensing degree of accuracy of tail gas air fuel ratio to non-heating type oxygen sensors 30 heating, thereby reduced the consumption of motorcycle electric energy, and then saved user cost.
The foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
