the first method is as follows: referring to fig. 3 and 4, the annular oil supply channels 3 of every two copper sleeves 2 are respectively communicated through the corresponding oil delivery channel 1c on the throttle casing 1, and each oil injector mounting hole 1b is respectively communicated with one annular oil supply channel 3 of the corresponding copper sleeve 2, so that an oil injector mounted in the oil injector mounting hole 1b can supply oil to one annular oil supply channel 3 firstly and then supply oil to the other annular oil supply channel 3 through the oil delivery channel 1c, and the two annular oil supply channels 3 can be supplied with oil simultaneously. In this way, the injector mounting holes 1b are all opened on the same side wall of the throttle housing 1, that is: the fuel injectors are all arranged on the same side wall of the throttle valve shell 1, so that the installation structure is more compact, and the space occupation is further reduced.

The second method comprises the following steps: the annular oil supply channels 3 of every two copper sleeves 2 are respectively communicated through corresponding oil delivery channels 1c on the throttle valve shell 1, and the oil injector mounting holes 1b are respectively communicated with the corresponding oil delivery channels 1 c.
