Accompanying drawing explanation
Fig. 1 is the plan view that detects the device of machine oil quality in the embodiment of the present invention;
Fig. 2 is the sectional drawing that detects the device of machine oil quality in the embodiment of the present invention.
In accompanying drawing: 1, safety cover; 2, sealing gasket; 3, fixing bolt; 401, the first electrode member; 402, the second electrode member; 5, resistance detection unit; 6, oil sump; 7, machine oil.
Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
In order to overcome the problem of prior art to the estimated accuracy deficiency of engine motor oil quality, the present invention proposes a kind of device that detects machine oil quality.Be illustrated in figure 1 the plan view of this device; Fig. 2 is its sectional view.The resistance detection unit 5 that this device comprises probe unit, is connected with probe unit, the control unit and the display unit that are connected with resistance detection unit 5.
Probe unit comprises the first electrode member 401 and the second electrode member 402, and these two electrode members do not contact, between the two every layout, here both are parallel to each other, and be positioned at oil sump bottom inside, therefore need only organic oil in oil sump, can extend in machine oil 7.Destroy the first electrode member 401 and the second electrode member 402 when preventing filling engine oil, this device also comprises safety cover 1 and sealing gasket 2, safety cover 1 by sealing gasket 2 mucilage bindings in the draw-in groove of resistance detection unit 5.
Display unit receives after the resistance information of resistance detection unit 5 transmissions, shows this resistance value.
Control unit by this value and the needs of setting more the resistance threshold of change engine oil compare, calculate machine oil factor of merit.Machine oil factor of merit is higher, shows that the quality of machine oil is higher; It is lower shows that machine oil quality is lower.And because machine oil 7 is dielectrics, its electric conductivity is along with the continuous increase of engine scuffing chip and the decomposition of additive and increase, so machine oil quality is poorer, this resistance value is larger, and machine oil factor of merit is lower.In addition, control unit is also connected with display unit, to display unit transmitter oil quality coefficient.Display unit receives after this information, shows this machine oil factor of merit.
In order to remind more intuitively car owner's change engine oil more in time, this device also comprises the alarm unit being connected with control unit.After control unit computer oil quality coefficient, the machine oil factor of merit threshold value of machine oil factor of merit and setting is compared, if machine oil factor of merit lower than this threshold value, illustrates that machine oil quality is lower, can affect the life-span of motor, arrived when needing to change.Now control unit is to alarm unit sending action signal, and alarm unit sends warning message after receiving this actuating signal, and prompting car owner is change engine oil more.
Above-mentioned control unit can be integrated in control unit of engine (ECU), is completed the work of its analysing and processing by ECU.
The invention is not restricted to above-described embodiment, wherein some element or assembly can be replaced with by those of ordinary skills other parts or assembly.For example,, wherein for directly the first electrode member 401 and second electrode member 402 of contact machine oil can replace with other habitual parts such as two iron wires or two resistance wires.
The device that the present invention detects machine oil quality can detect machine oil quality in real time, is unlikely to also not change when machine oil quality is too low, guarantees that engine operation is in the optimum state; Meanwhile, also avoided when machine oil need not be changed, by replacing in advance blindly, effectively providing cost savings.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiments, and General Principle described herein is applied in other embodiments and needn't passes through performing creative labour.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not departing from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
