Abstract
The utility model provides a device for improving lubrication performance of a turbocharger. A compressor casing 18 and a turbo shell 10 are respectively connected with two ends of a middle shell 4 whose top and bottom are respectively opened with an oil inlet 4-1 and an oil outlet 4-2. Outer part of the oil outlet is connected with an oil back pipeline 14 which is provided with a check valve 15. Moreover, in the middle shell, the lubricating oil with a certain oil pressure flows out from the check valve and the oil back pipeline, and the check valve is a ball type check valve which can adjust the pressure or a valve core type check valve which has perfect sealing performance. The device has the advantages of reducing the fuel consumption of engine, reducing engine abrasion and prolonging the service life as well as saving the lubricating oil.
Description
The utility model is the improvement to existing turbosupercharger.
Use at present the power that turbosupercharger improves motor widely.The lubricant oil of existing exhaust-gas turbocharger is supplied with by engine oil pump, and in-line and the fuel-displaced pipeline of the lubricant oil that oil pump pumps by pressurized machine circulate to reach in pressurized machine the increase device is lubricated and cooling purpose.Above lubricating system has the following disadvantages in actual applications: the one, and pressurized machine is the top that is positioned at motor, pressurized machine begins to run up when engine start, and this moment, engine oil pump just started, oil pressure and oily temperature are lower, can not supply with the enough lubricant oil of pressurized machine, cause the pressurized machine oil starvation to damage.The 2nd, the turbine of the pressurized machine inside, back of stopping since coherence also running up, and if kill engine this moment and will make the pressurized machine internal cause lack lubricant oil and produce wearing and tearing, and produce the backheat phenomenon.At present for solve above 2 all adopt behind engine start, lubricated and cooling that the back idling of stopping guaranteed pressurized machine in 3-5 minute, but this solution can increase the fuel consume of motor, causes unnecessary economic loss; In addition it has also increased the wearing and tearing of motor, makes motor shortening in working life, but also waste driver's quality time.The 3rd, when motor does not use for a long time (generally more than 7 days), must pull down the oil inlet pipe of pressurized machine, filler opening filling machine oil at pressurized machine, with this method pressurized machine is safeguarded, yet the lubricant oil that injects can flow out through oil outlet tube, so promptly cause waste, lubrication effect is bad again, and time-consuming, effort.
The purpose of this utility model is a kind of device that improves the turbocharger lubrication performance of design, at engine start with after stopping, it should have the fuel consume that reduces motor, the working life that reduces engine scuffing, prolongation motor, the characteristics of saving driver's time; Motor for a long time need not, when pressurized machine is safeguarded, it have save lubrication oil consumption, high lubricating effect, save time, the labour-saving characteristics.
The purpose of this utility model realizes in the following manner: the outside at the oil outlet 4-2 of pressurized machine middle case 4 is provided with an one-way valve 15, and return line 14 is connected on the oil outlet of one-way valve 15.The lubricant oil with certain oil pressure in the pressurized machine middle case 4 flows out by one-way valve 15 and return line 14.Behind engine start, the oil pressure that engine motor oil is supplied with is lower, and this moment, the pressure of lubricant oil can't be opened one-way valve 15, and the pressure oil in the pressurized machine middle case 4 can raise rapidly, and the pressurized machine that begins to run up is lubricated; During the motor proper functioning, the pressure oil in the pressurized machine in the middle case 4 can overcome the active force of one-way valve 15 inner springs, and spool is moved down, and opens valve port, and flows out by one-way valve 15 and return line 14, and lubricant oil is circulated in pressurized machine middle case 4; When stopping, engine stoping operation, the pressure of lubricant oil reduces in the pressurized machine middle case 4, the spool of one-way valve 15 moves up under the effect of spring, valve port is closed, lubricant oil can't flow out, and can accumulate some lubricant oil in the pressurized machine middle case 4 at this moment, to also being lubricated at the rotational parts of the pressurized machine that runs up owing to coherence; When motor for a long time need not, when pressurized machine was carried out oiling and safeguards, one-way valve 15 was because of the lower closed condition that is in of oil pressure of oiling, so lubricant oil can not flow out.
The utility model is when engine start, can be rapidly the oil pressure of the lubricant oil in the pressurized machine be raise, after the parking, can in pressurized machine, accumulate lubricant oil, therefore motor must not guarantee the lubricated and cooling of pressurized machine in idling 3-5 minute, therefore it has the motor of reduction and fuel consume, reduces the wearing and tearing of motor, prolongs the motor advantage in working life.When long-term no pressurized machine was safeguarded, it also had the consumption, the high lubricating effect that reduce lubricant oil, saves time, the labour-saving advantage.
