Abstract
The utility model discloses an oil return device of a turbocharger, which comprises an oil return pipe for connecting the turbocharger and a crankcase, and also comprises a bypass branch pipe for connecting the space above the engine oil level of the crankcase and the space in the middle body cavity of the turbocharger. In the technical scheme of the utility model, an oil return port of a turbocharger oil return pipe of a V-shaped or obliquely arranged supercharged engine is arranged below the engine oil level, and the middle body cavity of the turbocharger is communicated with the inside of the crankcase through the bypass branch pipe, so that the air pressure is same so as to prevent the leakage problem of the engine oil. The utility model has simple solution method and obvious effect.
Description
Technical field
The utility model relates to a kind of turbosupercharger of turbosupercharged engine, particularly a kind of return line with the pressurized machine of turbo charged motor that is used for V-type or arranges than wide-angle tilt.
Background technique
Generally adopt turbocharging technology on the internal-combustion engine at present, turbocharging technology has become the development trend of internal-combustion engine, is to promote performance, reduces the effective measures of discharging.And need run up during turbocharger operation, its bearing arrangement needs lubrication system to be lubricated guaranteeing to work reliably.And present turbosupercharger is higher to the arrangement requirement of lubrication system pipeline, as requires return line smoothly smooth and easy, and the angle of inclination is little, the location arrangements of return opening on motor at engine oil level with first-class.And these require just to be very difficult to reach for V-type engine or the motor that tilts and arrange at car load.This will bring the risk of potential lubricating oil leakage to turbosupercharger.If the long-term generator oil leakage of pressurized machine, at first oil consumption can increase, and increases client's burden, secondly, machine oil enters combustor inner cylinder by gas handling system, can cause the firing chamber, the turbo machine carbon distribution of valve mechanism and pressurized machine is serious, influences proper functioning, and performance is fallen.
Therefore, returning on the turbosupercharged engine that there is not device to be not suitable for the V-type turbosupercharged engine and is in tilted layout of present this turbosupercharger used.
The model utility content
The purpose of this utility model is to provide a kind of oil return apparatus of turbosupercharger for V-type engine or at the tilt motor arranged of car load.
The utility model for realizing the technological scheme that its purpose adopts is: a kind of oil return apparatus of turbosupercharger, comprise the return tube that connects turbosupercharger bottom and crankcase, also comprise the bypass arm that connects space in described crankcase engine oil level upper space and the described turbosupercharger.
Further, the attachment hole of described bypass arm on described crankcase is arranged on when piston is in lower dead center the lower edge of piston.Described bypass arm steel pipe.Be provided with in the steel pipe as described bypass arm and be flexible coupling.Be flexible coupling and also can be rubber hose.Described return tube is below the interface of described crankcase is arranged on engine oil level.
The technical solution of the utility model is arranged into below the engine oil level at the return opening of the pressurized machine return tube of V-type or the supercharged engine that is in tilted layout, to be connected in turbosupercharger and the crankcase by the bypass arm, make its air pressure identical, can guarantee equally that by above scheme the middle body cavity of pressurized machine and the crankcase of motor keep being communicated with, and can avoid aforesaid lubricating oil leakage problem.Solution is simple, and effect is remarkable.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the application schematic representation of the utility model embodiment 1 on V-type engine.
Fig. 2 is the application schematic representation of the utility model embodiment 2 on the motor that is in tilted layout.
Among the figure: 1. motor 2. gas exhaust manifolds 3. oil inlet pipes 4. turbosupercharger 5. bypass arms 6. return tubes 7. engine oil levels.
Embodiment
In the present embodiment, dispose turbosupercharger 4 on the V-type engine 1, turbosupercharger is installed in gas exhaust manifold 2 belows, and turbocharger operation needs oil lubricating and cooling, so be provided with oil inlet pipe 3 and return tube 6.But because the arrangement space restriction, the position of pressurized machine is very low, and return tube need be tilted to down layout, and return opening must be arranged into engine oil level below 7.Body cavity can't be communicated with crankcase in the middle of causing pressurized machine.Can be provided with a bypass arm in the above position of engine oil level this moment on return tube, be connected to crankcase, body cavity can't be communicated with crankcase in the middle of so can impelling pressurized machine, the function that return tube possessed of compensation normal arrangement is avoided the pressurized machine leakage of oil risk that is arranged into below the engine oil level to be brought because of return opening.
In the present embodiment: at the pressurized machine return tube of V-type or the supercharged engine that is in tilted layout under the return opening on the motor is difficult to be arranged into situation more than the engine oil level, the return opening of return tube can be arranged into below the engine oil level, but need make it smooth and easy as far as possible, in the position of the close pressurized machine intermediate in the upper end of return tube one bypass arm is set simultaneously, makes the bypass arm be connected to the crankcase of motor.Can guarantee equally that by above scheme the middle body cavity of pressurized machine and the crankcase of motor keep being communicated with, and can avoid aforesaid lubricating oil leakage problem.Solution is simple, and effect is remarkable.
Present embodiment has solved the V-type supercharged engine and has used the turbosupercharger return tube to be difficult to be arranged into problem more than the engine oil level at the return opening on the motor.It is that middle body cavity in order to make pressurized machine is communicated with the crankcase maintenance of motor that the return tube of past pressurized machine requires to be arranged in more than the engine oil level at the return opening on the motor, so that the gas of scurrying into from supercharger air compressor side and turbine pusher side can enter crankcase by return tube, discharge together with crankcase ventilation system, if this part gas of scurrying into can not be got rid of, and be sealed in the middle of the pressurized machine in the body cavity, the body cavity internal air pressure raises in the middle of will making, and causes machine oil to overflow to both sides.Because the particularity of V-type engine, be difficult to finish the art task from return opening, therefore, a bypass branch is set, be used for guaranteeing crankcase and the interior circulation of turbosupercharger specially, also get rid of when crankcase pressure raises unusually simultaneously, the situation that machine oil refluxes and overflows from the pressurized machine both sides can not occur
Embodiment 2, and as shown in Figure 2, present embodiment is a turbosupercharger oil return apparatus on a kind of turbosupercharged engine that is in tilted layout, and as shown in Figure 2, its structure is substantially the same manner as Example 1.
