Embodiment 1
[0033] Such as figure 1As shown, the automobile fuel-saving control system includes a control center 8, a multiplier 1, a fuel supply adjustment device 200 and a rotational speed sensor 300, wherein the multiplier 1 is arranged between the engine output shaft 21 and the wheel shaft 3 and is connected to the control The center 8 is connected, the oil supply adjustment device 200 is arranged on the oil circuit between the oil pump 100 and the engine 2 and connected with the control center 8 , and the rotational speed sensor 300 is arranged on the engine output shaft 21 and connected with the control center 8 .
[0034] Such as figure 2 As shown, the multiplier 1 includes a casing 11 and a sliding sleeve 14 partially arranged in the casing 11. The sliding sleeve 14 is connected with a shift fork 9 capable of one-way clutching of the engine output shaft 21 and the wheel shaft 3. The fork 9 is connected with the control center 8 through an electric control device. A ratchet whee...
Embodiment 2
[0039] Such as Figure 4 As shown, the content of embodiment 2 is basically the same as that of embodiment 1, the difference is that the shift fork 9 is connected with the control center 8 through the air control device, and the air control device includes an air pump 10, a cylinder 16, an air valve 17 and a return spring 7, The air pump 10 and the cylinder 16 are connected through an air circuit, and an air valve 17 is arranged on the air circuit between the air pump 10 and the cylinder 16 , and the control center 8 is connected with the air valve 17 . The cylinder 16 is located on the housing 11 and a piston 18 is housed in the cylinder 16 , and one end of the shift fork 9 is inserted in the cylinder 16 and can lean against the piston 18 . A return spring 7 located in the cylinder 16 is sheathed on the shift fork 9 , one end of the return spring 7 acts on the housing 11 , and the other end acts on the shift fork 9 . The opening and closing of the air valve 17 is controlled ...
Embodiment 3
[0042] Prepare the copper alloy raw material of the sliding sleeve, after melting, rough refining and refining, and then use the nitrogen powder spraying process to make copper powder under the conditions of nitrogen pressure 1.6Mpa, nozzle diameter 4 mm, and air inlet angle 45°; The composition and mass percentage of copper alloy are: Mn: 0.20%, Si: 0.54%, Sn: 0.26%, Bi: 0.08%, Cr: 0.48%; Zn: 2.8%, the balance is Cu and unavoidable impurities ; The particle size distribution of the copper powder is: the content of particles below 50 μm is 10%, the content of 50-100 μm particles is 50%, and the balance is 100-150 μm particles.
[0043] Screen copper powder, mix copper powder with graphite powder and then grind; the particle size of graphite powder is 40-60 μm.
[0044] Sinter the powder at 810°C and process it into a sliding sleeve blank;
[0045] The finished sliding sleeve can be obtained by heat-treating the blank of the sliding sleeve. The heat treatment is an annealing ...
