[0038] When in use, first start the starting motor configured on the diesel engine 11, so that the crankshaft on the diesel engine 11 drives the rotating shaft 51 to rotate through the belt drive, and the rotating shaft 51 rotates so that the cam 52 drives the second piston rod 54 to reciprocate through the connecting rod 53, so that the second piston rod 54 drives the second piston 55 to reciprocate inside the second piston cylinder 56 and pushes the gas to the regulating cylinder 41 through the fourth exhaust hole 562 and the fourth air inlet hole 412, and the gas enters the inside of the supercharging cylinder 21 through the third exhaust hole 411 and the first air inlet hole 212 on the regulating cylinder 41, so that the internal pressure of one chamber of the supercharging cylinder 21 is continuously increased and pushes the pressure plate 213, so that the pressure plate 213 continuously squeezes the gas of another chamber inside the supercharging cylinder 21, so that the gas in the other chamber of the supercharging cylinder 21 is compressed, and when the pressure plate 213 is pushed to the limit column 223, the pressure plate 213 pushes the limit column 223 so that the sliding rod 222 drives the sealing block 221 to slide inside the air supply cylinder 22, so that the pressure plate 213 is pushed to the limit column 223. The hole 211 and the first exhaust hole 224 are opened, so that the compressed gas enters the interior of the air storage cylinder 23. When the pressure plate 213 is pushed to the extreme position, the pressure at the third exhaust hole 411 increases continuously and exceeds the rated pressure of the overflow valve. At this time, the gas enters the first piston cylinder 42 through the overflow port of the overflow valve and the air vent of the first piston cylinder 42, so that the internal pressure of the first piston cylinder 42 increases continuously, so that the first piston 43 pushes the first piston rod 44 to slide into the regulating cylinder 41, so that the first piston rod 44 pushes the slider 46 to slide inside the regulating cylinder 41, so that the gas enters another chamber of the supercharging cylinder 21 through another third exhaust hole 411, so that the push plate moves in the opposite direction, so that the compressed gas continuously enters the interior of the air storage cylinder 23, so as to ensure that the gas inside the cylinder of the diesel engine 11 is all compressed gas, increase the air intake in the cylinder, and solve the problems of thin air in high altitude areas, insufficient engine air intake, difficulty in engine starting, and insufficient diesel combustion. Example 2

[0039] In actual use, it was found that due to the different gas pressures at different altitudes, the intake volume of the cylinders inside the diesel engine group was different. In order to ensure that the mixing ratio of fuel and air reaches the optimal state and further make the fuel burn fully, further improvements are made on the basis of the above embodiment.

[0040] See also Figure 2 and Figure 7 As shown, the injector 3 is mounted on the diesel engine 11, combined with Figure 8As shown, the injector 3 has an oil inlet chamber 35 and an adjusting chamber 36. The injector 3 is provided with a throttling member 31. One end of the throttling member 31 is slidably connected to the inner wall of the adjusting chamber 36, and the other end of the throttling member 31 extends into the oil inlet chamber 35. One end of the throttling member 31 inside the oil inlet chamber 35 can cooperate with the bottom of the oil inlet chamber 35 to control the injection time. The inside of the injector 3 is provided with an adjusting member 32, and the adjusting member 32 can adjust the injection amount of the injector 3 according to the intake pressure of the diesel engine 11.

[0041] See also Fig.10 As shown, a vent hole is opened at one end of the air cylinder 23 away from the booster cylinder 21, a pressure measuring plate 233 is slidably connected inside the air cylinder 23, a pneumatic spring is arranged inside the air cylinder 23, the air cylinder of the pneumatic spring is fixedly connected to the side wall of the end of the air cylinder 23 away from the booster cylinder 21, and the telescopic rod of the pneumatic spring is fixedly connected to the pressure measuring plate 233.

[0042] See also Figure 8 As shown, the regulating chamber 36 of the fuel injector 3 is provided with a third air inlet hole 33, and the third air inlet hole 33 is connected with the air storage cylinder 23 through a vent pipe. A first elastic member 34 is arranged in the fuel injector 3, one end of the first elastic member 34 is fixedly connected to one end of the throttling member 31 inside the regulating chamber 36, and the other end of the first elastic member 34 is fixedly connected to the inner bottom surface of the regulating chamber 36 of the fuel injector 3, and a nozzle is fixedly connected to the fuel injector 3, the regulating member 32 is slidably connected to the throttling member 31 and penetrates the throttling member 31, one end of the regulating member 32 is slidably connected to the inner wall of the regulating chamber 36, and the other end of the regulating member 32 extends into the oil inlet chamber 35, and one end of the regulating member 32 in the oil inlet chamber 35 can cooperate with the nozzle, wherein the fuel injector is a prior art and will not be described in detail here.

[0044] On the basis of the above embodiment, when in use, due to different altitudes and different degrees of air rarefaction, the gas in the atmosphere is compressed to different degrees by the supercharging cylinder 21, thereby causing different pressures inside the air storage cylinder 23. When the gas compression increases, the cylinder air intake of the diesel engine 11 increases, and the pressure inside the air storage cylinder 23 increases. At this time, the pressure plate 233 is pushed, so that the gas enters the injector 3 through the vent hole, so that the adjusting member 32 slides inside the adjusting chamber 36, so that the larger the opening between the adjusting member 32 and the injector nozzle, the greater the oil output of the injector 3. On the contrary, when the gas compression is small, the smaller the oil output of the injector 3. When the injector 3 needs to spray fuel, the throttling member 31 slides upward in the adjusting chamber 36 by energizing the electromagnet. At this time, the diesel enters the cylinder through the injector nozzle, thereby ensuring that the mixing ratio of fuel and air reaches the optimal state, and controlling the injection time of the injector 3, further making the fuel fully burn, reducing the engine fuel consumption, and increasing the fuel economy.
