Detailed description of the invention
With reference to accompanying drawing, the most identical reference corresponds to same or analogous parts, Fig. 1 schematically shows vehicle 10, such as automobile, and it includes engine pack 12.Engine pack 12 include internal combustion engine 14, and it is configured to advance vehicle 10.Wherein, internal combustion engine 14 uses oil O to be used for Lubrication.Engine pack 12 also includes oil sump 16, and it is attached to internal combustion engine 14.Thus, oil O can Flow between internal combustion engine 14 and oil sump 16.Specifically, oil O Castor Oil internal combustion engine 14, then Flow to oil sump 16.Oil sump 16 then collect oil O, but oil O be not increased to predetermined oil level L it On.Engine pack 12 also includes the oil pump 18 being attached to oil sump 16.Thus, oil pump 18 can be by Oil O moves to another vehicle part 20, such as oil duct from oil sump 16.Oil O can be then from vehicle portion Part 20 (such as, oil duct) flowing returns to internal combustion engine 14.
For maximum fuel efficiency during the operation of internal combustion engine 14, oil O should have the oil of optimization and glue Degree.Oil viscosity can change by adjusting the temperature of oil O.Correspondingly, oil sump 16 is heated or cooled In oily O be useful, in order to adjust oil viscosity.The engine pack 12 disclosed now can be independent of The oily O that the oily flow velocity that oil pump 18 produces is heated or cooled in oil sump 16.This heats up at internal combustion engine 14 And particular importance in the relatively low sight of engine speed.In this sight, adding deep fat O can reduce Its viscosity, thus minimizes the friction of internal combustion engine 14.Propose, by using oil sump disclosed here 16, during the temperature rise period, the fuel efficiency of internal combustion engine 14 can be improved about relative to conventional engines One of percentage (1) is to 1 five (1.5).
Engine pack 12 also includes heat transfer fluid source 22, and it can keep heat transfer fluid F.Heat Transmission fluid F can be adapted for any fluid (such as, liquid) of transmission heat.As non-limiting example Son, heat transfer fluid F can be coolant, such as ethylene glycol.Fluid source 22 and input channel 24 (example As, conduit, pipeline, pipe etc.) fluid communication.Input channel 24 outside oil sump 16, and Between oil sump 16 and fluid source 22, fluid couples.Correspondingly, heat transfer fluid F can be from fluid source 22 flow to oil sump 16.Fluid transmission pump 26 is also coupled to input channel 24, in order to by heat transfer stream Body F is moved to oil sump 16 from fluid source 22 by input channel 24.
Input channel 24 and thermal source 28 thermal communication.Therefore, can to add heat flow logical by input for thermal source 28 The heat transfer fluid F in road 24.As non-limitative example, thermal source 28 can be exhaust manifold, aerofluxus Recirculating system, turbocharger, engine cylinder-body, hood or a combination thereof.No matter used The kind of thermal source 28 how, and heat H can be in the heat transfer fluid F flowed by input channel 24 and warm Transmit between source 28.
Input channel 24 and cooling source 30 thermal communication.Therefore, cooling source 30 can cooled flow pass through defeated Enter the heat transfer fluid F of passage 24.As non-limitative example, cooling source 30 can be vehicle 10 Cooling system.Regardless of the kind of the thermal source 30 used, heat H can be in flowing by input Transmit between heat transfer fluid F and the cooling source 30 of passage 24.
As discussed in detail below, oil sump 16 have drain pan passage 32 (such as, sheath, hole, open Mouthful), it is formed by oil sump body 36 and is in fluid communication with input channel 24.Correspondingly, heat transfer Fluid F can flow between input channel 24 and drain pan passage 32.When flowing is by drain pan passage 32 Time, heat can be at the oily O in being arranged in oil sump 16 and the heat transfer stream by drain pan passage 32 that flows Transmit between body F, as described below.Engine pack 12 is additionally included in the output outside oil sump 16 Passage 34 (such as, conduit, pipeline, pipe etc.).Output channel 34 is with drain pan passage 32 fluid even Logical.Correspondingly, once heat in flowing by the heat transfer fluid F of drain pan passage 32 and layout Transmitting between oily O in oil sump 16, heat transfer fluid F can be in drain pan passage 32 and output channel Flow between 34.It is contemplated that oil sump 16 can include one or more drain pan passage 32.
With reference to Fig. 2-3, oil sump 16 is completely or partially made up of substantially rigid material, such as rigidity Metal material, and be configured to keep oil O.It is contemplated that oil sump 16 can be made by casting.But It is that other suitable manufacture methods can be used for making oil sump 16.Regardless of the manufacture method used, oil Drain pan 16 includes the oil sump body 36 with multiple wall 38.Such as, in the embodiment shown, the oil end Shell 16 includes multiple sidewall 38a and at least one diapire 38b of interconnection sidewall 38a.Oil sump body 36 limit display device surface 40 and the outer drain pan surface 42 relative with display device surface 40.Display device table Face 40 limits the chamber 44 opened wide, and described chamber configuration is, is shaped to and is sized to collect And keep oil O.
Drain pan passage 32 extends through at least one described wall 38, and is fully disposed in display device surface 40 And between outer drain pan surface 42.In the embodiment shown, drain pan passage 32 extends through at least diapire 38b. However, it can be assumed that drain pan passage 32 can extend through sidewall 38a.Regardless of its accurate location, the end Shell passage 32 is configured to transmit heat transfer fluid F, in order to promote to be arranged in the oil in open cavity 44 O (Fig. 1) and flowing are by the heat transfer between the heat transfer fluid F of drain pan passage 32.
Drain pan passage 32 can have a general U-shape, and have by input channel 24 (Fig. 1) with The entrance 46 that fluid source 22 (Fig. 1) is in fluid communication.Therefore, heat transfer fluid F can be at fluid source 22 And flow between drain pan passage 32.Additionally, drain pan passage 32 includes being in fluid communication with output channel 34 Outlet 48.Thus, pass through in the heat oily O in the chamber 44 of oil sump 16 and flowing Between the heat transfer fluid F of drain pan passage 32 after transmission, heat transfer fluid F can be from drain pan passage 32 It flow to output channel 34.Because the oily O in oil sump 16 can be by from heat transfer fluid F exchanged heat Measuring and be cooled, engine pack 12 need not oil cooler.Thus, engine pack 12 (and because of This vehicle 10) not there is the oil cooler for cooling down the oily O in oil sump 16.
With reference to Fig. 5, for the oily O being heated or cooled in oil sump 16, engine pack 12 can basis Method 100 is used.Method 100 starts in a step 102.In a step 102, heat transfer fluid F was heated or cooled before being introduced in drain pan passage 32.In order to heat heat transfer fluid F, as Upper described, when heat transfer fluid F flowing is by input channel 24, heat can from thermal source 28 (such as, Exhaust manifold) it is delivered to heat transfer fluid F.In order to cool down heat transfer fluid F, as heat transfer fluid F When flowing is by input channel 24, heat can be delivered to cooling source 30 from heat transfer fluid F.Then, Method 100 marches to step 104.
Step 104 requirement, when oil O is arranged in the chamber 44 of oil sump 16, introduce heated or Cooled heat transfer fluid F is in drain pan passage 32.At this moment, heat transfer fluid F is from entrance 46 Flow by drain pan passage 32 to outlet 48.When heat transfer fluid F flowing is by drain pan passage 32, The heat oily O in the chamber 44 being arranged in oil sump 16 and the flowing heat transfer by chassis passage 32 Transmit between fluid F, in order to cool down oil O or make it heat up.Then, method 100 proceeds to step 106。
In step 106, heat transfer fluid F enters to export by outlet 48 outflow drain pan passage 32 and leads to Road 34.Now, heat transfer fluid F can be directed back into input channel 24, in order to is recycled.
The although better model performing the present invention has been carried out detailed description, but art technology Personnel can learn the many replacement designs for implementing the present invention within the scope of the appended claims And embodiment.
