Embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with accompanying drawing
It is described in detail on step ground.
When engine operates, the parts surface that relative motion be present directly contacts, just among this constantly " stroking gently ", mill
Damage produces immediately, and at the same time, this phenomenon can also corrode a part of power.In order to lift engine life, the profit of engine
Sliding system is all the time among improvement.Among the lubricating system of engine, machine oil is a highly important role, and it can be reduced
The degree of wear between mechanical part, reduce the kinetic equation loss of engine interior.
The machine oil for emulsion occur contains water and is mingled with bubble, and this obviously influences whether that machine oil is lubricating, clean, dissipated
The performance of heat etc..Emulsification is to form the process of emulsion after strong stirring by two kinds of immiscible liquid.With regard to machine
For oily emulsion, both immiscible liquid are machine oil and water, and reaching certain proportion machine oil after they are mixed will
There is the phenomenon emulsified, low temperature environment and relatively low oil temperature can not evaporate the moisture in machine oil in time, and moisture is in machine oil
Gradually accumulation, reaches certain proportion, emulsification is formed.
When the engine runs, the gaseous mixture in combustion chamber (fuel oil and air) can scurry into crankcase, scurry into crankcase
Gaseous mixture machine oil can be caused to go bad, so as to produce fuel dilution, and then have influence on lubricating system.
Lubricating oil emulsion and oil dilution can aggravate under low-temperature condition, therefore, for lubricating oil emulsion under low-temperature condition and machine
The control of the phenomenon of oil dilution is particularly important.
To rationalize control lubricating oil emulsion and oil dilution phenomenon, as shown in figure 1, the invention provides one kind to control machine oil
Emulsification and the method for fuel dilution, including：
S1. monitors environment temperature and running car behavioural characteristic.
Specifically, the running car behavioural characteristic includes automobile single operating range, automobile starting stopped working apart from last time
Time interval, automobile single running time, the machine oil temperature of the traveling water temperature value of vehicle traveling process and/or vehicle traveling process
Angle value.
S2. the serious of lubricating oil emulsion and fuel dilution is obtained according to the environment temperature and the running car behavioural characteristic
Degree.
Specifically, lubricating oil emulsion and the exact value of the order of severity of fuel dilution are difficult to calculate, and the meter of its exact value
Computing cost is also too high caused by calculation, therefore, institute is represented with the aggregate-value of predeterminable event frequency in the embodiment of the present invention
State the order of severity of lubricating oil emulsion and fuel dilution.The aggregate-value of the predeterminable event frequency is recorded with counter.
Predeterminable event often occurs once, and lubricating oil emulsion rate and fuel dilution will be more serious, therefore, the predeterminable event frequency
Aggregate-value and lubricating oil emulsion rate and fuel dilution rate be positive correlation.
If S3. the estimate of lubricating oil emulsion and the order of severity of fuel dilution exceedes frequency threshold value, display reminding information and/
Or alleviate the solution of lubricating oil emulsion and fuel dilution.
Specifically, the frequency threshold value can be set based on experience value, such as 30 times, can be with when more than frequency threshold value
Display reminding information is with to user's progress alarm, further, alarm on the central control panel or instrument board of automobile
Position can prompt position identical with the vehicle-mounted diagnostic alarms of tradition, so easily cause consumer attention to be paid attention to.
Further, the solution for alleviating lubricating oil emulsion and fuel dilution can also be provided in the signal language of alarm
Scheme, it is desirable to which user carries out operation according to the solution can eliminate alarm.Specifically, the solution can be with
It is required that user is operated according to some operating mode, for example " your love car please draw high fast half an hour because long-time short distance travels
More preferably to protect your love car ".Further, if client in time by solution operate, next time start vehicle when can be again
Alarm is carried out, until client is operated by solution, alarm can be eliminated.
Specifically, as shown in Fig. 2 described obtain machine oil breast according to the environment temperature and the running car behavioural characteristic
Change and the order of severity of fuel dilution includes：
S21. after automobile starting, judge whether environment temperature is less than environment temperature threshold value.
S22. if so, then judging whether automobile starting is more than time interval threshold value apart from the time interval that last time stops working.
S23. if so, then continuing to monitor motor vehicle behavior travelling characteristic until automobile flameout.
S24. judge whether automobile single operating range is less than distance threshold after automobile flameout.
S25. if so, then judging predeterminable event, Counter Value adds 1.
Specifically, the environment temperature threshold value, time interval threshold value and/or distance threshold can be set based on experience value.
The counter can be provided by the electronic control unit of automobile.
In the embodiment of the present invention, after automobile starting：When environment temperature is less than -10 DEG C, automobile single traveling is less than 5km, and
Automobile starting is more than 60 minutes apart from the time interval that last time stops working, then ECU rolling counters forwards add 1 after automobile flameout.
If the value of the counter exceedes frequency threshold value, judge that lubricating oil emulsion and fuel dilution are serious, exported to user
Prompt message and the solution for alleviating lubricating oil emulsion and fuel dilution.
If the value of counter exceedes frequency threshold value, user can cause counter O reset according to solution operation, prompt
Information disappears, or user can also arrive 4S automobiles shop and carry out Motor Maintenance, for example changes machine oil, will be counted by 4S shops staff
Number device is reset.
Further, if in the case where the value of counter is no more than frequency threshold value, if first resets event, the second clearing
Event the 3rd resets event, then Counter Value is reset；
