The beneficial effect that the utility model is compared with prior art produced is:
Lubricating fitting is shut down in this turbosupercharging; when the engine operates; the transfer case outputting power of motor is utilized to drive vacuum pump to rotate; vacuum pump work makes the vacuum aided chamber of apotheca produce powerful negative pressure; powerful negative pressure makes the tension force of piston overpowers tension spring move to this one end, vacuum aided chamber; tension spring obtains spring energy storage, and meanwhile, partial high pressure lubricating oil is also stored in the pressure oil cavity of apotheca by the movement of piston.During engine operation, lubricant oil main oil gallery continues to exhaust gas turbocharger fuel feeding, in order to the assembly of lubrication and cooling exhaust gas turbocharger.
Lubricating fitting is shut down in this turbosupercharging, and after motor is shut down, lubricant oil main oil gallery is switched to off working state, and lubricant oil main oil gallery no longer continues to exhaust gas turbocharger fuel feeding.Now, motor transfer case also no longer outputting power to vacuum pump, vacuum pump does not reoffer powerful negative pressure, the negative pressure in the vacuum aided chamber of apotheca is caused to be lost, tension spring release spring energy storage, tension spring pushes piston to working end, the now movement of piston provides pressure to the pressure lubrication oil in apotheca pressure oil cavity, pressure lubrication oil in pressure oil cavity is reverse in branch's oil circuit is delivered to transport pipe, due to the effect of one-way valve, pressure lubrication oil is made to flow to exhaust gas turbocharger, continue to turbocharger fuel feeding, the amount of the pressure lubrication oil in pressure oil cavity can guarantee the pressure lubrication oil supply exhaust gas turbocharger of 3 ~ 5 minutes according to flow velocity and circuit design, and provide lubrication to exhaust gas turbocharger bearing, heat is taken away, substantially prolongs the working life of exhaust gas turbocharger.
Even if so when motor is shut down; also the oil circulation of follow-up short time can be had; fluid can take away the heat of exhaust gas turbocharger after engine stop; ensure lubrication effect simultaneously; avoid stopping engine running; make turbocharger supply lubricant oil not enough, heat can not scatter and disappear in time, makes turbocharger cause the situation of the damage on equipment to occur.
This turbosupercharging shut down lubricating fitting reasonable in design, structure is simple, safe and reliable, easy to use, be easy to safeguard, have good value for applications.
