Embodiment
Below in conjunction with embodiment the utility model is further described, but the claimed scope of the utility model is not limited to the scope that mode of execution is expressed.
Fig. 1 the utility model improves the unidirectional enrichment-system schematic representation of engine power performance.This unidirectional enrichment-system is on the automobile of original use Carburetor, by 4 belows of the closure in the Carburetor, add unidirectional enrichment-system in the enriching pipeline 10 of the outlet top of mixed gas, this unidirectional enrichment-system mainly comprises gasoline channel 2, sensor 7, nitrous oxide gas passage 5, nozzle 9.This unidirectional enrichment-system is to be used for adding nitrogen oxide to original gasoline-air mixture, and adds required gasoline.
As shown in Figure 1, closure 4 top sidewalls are connected with float chamber 6 by pipeline in the Carburetor 8.Closure 4 belows in the Carburetor 8 are provided with enriching pipeline 10, and in enriching pipeline 10, the nozzle 9 nitrous oxide gas passage 5 interior with stretching into the enriching pipeline is connected, and can spray into nitrous oxide gas as required in enriching pipeline 10; Gasoline channel 2 one ends stretch in the enriching pipeline 10, and outlet is provided with nozzle, and the other end is communicated with float chamber 6, gasoline channel 2 is provided with electric control valve 1, electric control valve 1 is electrically connected with relay 3, and is connected with running computer ECU signal, can spray into gasoline as required in dense pipeline 10; Dense pipeline 10 inner bottom parts also are provided with sensor 7, and sensor 7 is connected with car running computer ECU.Nitrous oxide gas passage 5 is provided with solenoid valve (not showing among the figure), and solenoid valve is connected with running computer ECU signal, set electric control valve 1 and relay 3 on the logical gasoline channel 2 of its principle.Relay 3 can be selected OKA21 type or OKA2 type relay for automobile for use, also can select the relay for automobile of other models for use.Running computer ECU select for use have the programmable function ECU of car all can, its programming is carried out following selection according to the needs of power of vehicle:
When automobile need not be with high-power operation, electric control valve 1 guaranteed the regular supply of motor by original mixed gas by running computer ECU control.When gas pedal did not show needs full load power, the electromagnetic valve of control nitrogen oxide was closed, and does not feed nitrous oxide gas, and petrol engine is kept its original operating mode.
Need increase substantially the output power of motor as the driver, when increasing its power, closure 4 reaches maximum, and relay 3 is connected, electric control valve 1 is opened, and making additionally needs gasoline to join enriching pipeline 10 by gasoline channel 2 from float chamber 6.Simultaneously, open the electromagnetic valve of nitrogen oxide, nitrogen oxide sprays in nozzle 9 sprays into enriching pipeline 10 by gas channel 5.
