FIG. 3 is a flowchart illustrating an embodiment of the automatic engine oil compensation control method; some embodiments, an engine oil automatic compensation control method, includes:
step S1: when the engine is running, a first preset time period T is set 1 Within a first preset time period T 1 Internal multiple-time obtaining of engine oil level value L of engine oil tank n ；
At a first preset time length T 1 Internal multiple-time obtaining of engine oil level value L of engine oil tank n Also for obtaining level value L of sump n The number of times of execution is limited, for example: at a first preset time length T 1 And the time intervals between the oil level values acquired for multiple times can be equal or unequal.
Preferably, the first preset time period T 1 The range of (A) is as follows: 2-4min, more preferably, the first preset time period T 1 Comprises the following steps: and 2 min. The first preset time length T 1 The range of (1) is only normal roads, and the first preset time length T can be prolonged when meeting the road conditions with more slopes such as mountainous areas, mining areas and the like 1 (ii) a Thus is provided withOf a first predetermined duration T 1 The engine oil level value condition in the engine can be known within a short time, and whether the engine is automatically compensated by engine oil can be judged accurately on the next step.
Preferably, the range of the number of times of the multiple acquisition is: 30 times/min-60 times/min, more preferably 60 times/min. The advantage of setting like this can learn the whole of the oil level value in the engine in the short time, is convenient for to the oil level value real-time supervision in the engine.
It should be noted that, in the present embodiment, the liquid level sensor for acquiring the oil level value of the oil tank is located on the oil pan, so as to accurately detect the oil level value in the oil tank when the road surface is flat; however, since the liquid level sensor can only obtain a certain value, the liquid level sensor cannot accurately obtain the current oil level value when the vehicle runs on an uphill or downhill slope or jolts, and therefore, a timing device is added for timing. The oil level value of the oil tank needs to be collected for multiple times within a certain time, and the purpose is to confirm whether the engine is lack of oil or not through multiple times of collection. Of course, under normal engine operation, the oil level value L of the oil tank is obtained for the first time whether timing is performed or not 1 That is, the timing device firstly counts time or the liquid level sensor firstly obtains the oil level value of the oil tank, and all the time can be within the first preset period T 1 In the method, the oil level value L of the oil tank is obtained every few seconds n Then the method is finished; moreover, the number of seconds of the interval may be the same or different; specifically, the setting may be performed by the manufacturer or the model of the engine, which is not limited in this embodiment. It should be noted that the oil tank in the present embodiment is a portion of the oil pan in the lower portion of the engine. Of course, individual vehicles also have a sump that separately provides oil to the engine, and the oil pan of the engine is also referred to herein as the sump.
Step S2: according to the first preset time length T 1 All the oil level values L obtained internally n Determining whether to charge the engine with a first preset level valueMachine oil automatic compensation.
Specifically, in a first preset period T 1 In, can obtain the machine oil level value L of oil tank once every several seconds n (ii) a For example: recording the level value L of the oil in the sump every few seconds 1 ，L 2 ，……，L n . The above oil level value L 1 ，L 2 ，……，L n Respectively compared with a first preset liquid level value. And the inaccuracy of the oil level value caused by road bump is prevented.
More specifically, the method comprises the following steps:
step S21: if all the engine oil level values L 1 ，L 2 ，……，L n If the oil level values are smaller than the first preset level value, controlling an auxiliary engine oil tank to automatically compensate engine oil for the engine; specifically, if the auxiliary engine oil tank acquires a signal for automatically compensating the engine oil to the engine, the electromagnetic valve is controlled to be opened. In order to prevent the reason that high-level lubricating oil in the auxiliary engine oil tank directly flows into an engine oil pan (namely an engine oil tank) due to direct pressure utilization, the engine is damaged due to excessive lubricating oil in the engine, an electromagnetic valve is generally arranged on a pipeline of the engine oil tank and the auxiliary engine oil tank, and therefore engine oil is replenished into the engine oil tank by controlling the opening and closing of the electromagnetic valve. Under general conditions, the relative position height of the auxiliary engine oil tank is higher than the maximum liquid level height of lubricating oil of an oil bottom shell in an engine, and if the engine needs to be automatically replenished, the opening of the electromagnetic valve can be controlled, so that the lubricating oil in the auxiliary engine oil tank automatically flows into the oil bottom shell of the engine due to pressure difference, and the effect of replenishing the lubricating oil of the engine in time is achieved.
When L is 1 < first predetermined level value, and, L 2 < first preset level value, and, … …, and, L n And when the value is less than the first preset liquid level value, controlling the electromagnetic valve in the auxiliary engine oil tank to open, and performing automatic engine oil compensation on the engine. At all said oil level values L 1 ，L 2 ，……，L n When the values are all smaller than the first preset liquid level value, the engine is lack of engine oil, therefore, the electromagnetic valve of the auxiliary engine oil tank needs to be controlled to be opened at the same time,the sump is replenished with oil and, at the same time, provides oil to the engine. Thus, only in the first preset period T 1 If all the engine oil level values L in the engine oil tank are smaller than a first liquid level set value, the auxiliary engine oil tank can be controlled to automatically compensate the engine oil for the engine; the liquid level fluctuation caused by jolting or uphill and downhill in the running process of the whole vehicle can be avoided, and the detection value is more accurate.
If any engine oil level value L n More than or equal to the first preset liquid level value, resetting the first preset time length T 1 And at the reset first preset time length T 1 Obtaining the oil level value L of the oil tank for multiple times n It should be noted that the first preset time period T is reset 1 Then, the oil level value L of the oil tank is obtained n The first preset duration T which needs to be newly acquired in real time, i.e. newly set 1 Reacquired latest sump oil level value L n Rather than the last cycle or history data.
When L is 1 Not less than the first preset level value, and/or, L 2 Not less than a first predetermined level value, and/or, … …, and/or, L n When the value is more than or equal to the first preset liquid level value, the engine does not lack engine oil at a certain moment or a certain moment, and the first preset period T cannot be guaranteed 1 The engine is bound to be out of oil, and therefore, the cycle of the next period (i.e., the reset first preset duration T) is continued 1 ) I.e. the oil of the sump continues to be taken.
It should be noted that the first preset level value is less than the second preset level value. The first set level value must be greater than the level value of the minimum oil required in the engine running process, and the second set level value must be less than the level value of the maximum oil required in the engine running process, so that the oil in the oil tank can be ensured to enable the engine to normally run for a long time.
Further, step S21 further includes:
step S211, in the automatic engine oil compensation, continuously acquiring the engine oil level value L of the engine oil tank Supplement device (ii) a The purpose is that the control auxiliary oil tank is started toWhen the machine carries out automatic engine oil compensation, the remaining engine oil in the auxiliary engine oil tank can not be determined, so the level value L of the engine oil in the engine oil tank needs to be continuously monitored Supplement device (ii) a It should be noted that, because the liquid level sensor is disposed on the oil pan, the liquid level sensor can only obtain the oil level value in the oil tank, and cannot obtain the oil level value in the auxiliary oil tank or the remaining oil in the auxiliary oil tank, and therefore, it is necessary to continuously obtain the oil level in the oil tank. Thus, it was confirmed that the organic oil in the sub-tank was continuously replenished into the oil tank.
Step S212, judging the oil level value L Supplement device Whether the value is greater than or equal to a second preset liquid level value specifically comprises the following steps:
if the oil level value L Supplement device And controlling the auxiliary engine oil tank to stop performing automatic engine oil compensation on the engine when the value is larger than or equal to a second preset liquid level value, and simultaneously controlling the electromagnetic valve to be closed when the auxiliary engine oil tank acquires a signal for stopping performing automatic engine oil compensation on the engine. Indicating that the oil in the sump is sufficient for normal operation of the engine, the solenoid valve controlling the auxiliary sump is closed to stop supplying oil to the sump, but the sump continues to provide oil to the engine.
If the oil level value L Supplement device If the value is less than the second preset liquid level value, the automatic engine oil compensation is continuously carried out.
It should be noted that the hydraulic level value L is set Supplement device When the value is larger than or equal to the second preset liquid level value, the engine oil in the engine oil tank can ensure the normal operation of the engine, and therefore, the engine oil compensation on the engine can be stopped. On the contrary, it is stated that the normal operation of the engine cannot be guaranteed by the engine oil supplied from the auxiliary engine oil tank to the engine oil tank, and therefore, the auxiliary engine oil tank needs to be controlled to continuously supply the engine oil to the engine oil tank, so that the engine oil is continuously compensated from the engine oil tank to the engine.
Controlling the auxiliary engine oil tank to automatically compensate engine oil for the engine, further comprising:
step S213, judging and controlling the time length T for automatically compensating engine oil from the auxiliary engine oil tank to the engine 2 Whether or not it is greater than or equal to the second presetLength t 2 And, an oil level value L Supplement device Whether the value is less than a second preset liquid level value or not;
if the duration T of automatic engine oil compensation 2 Not less than second preset time t 2 And, an oil level value L Supplement device If the value is less than the second preset liquid level value, warning information is output. If the above situation occurs, it is described that the remaining oil in the sub-tank cannot be replenished to the oil tank, and further cannot be automatically compensated for the engine. Therefore, the driver can be prompted to add the engine oil after the engine oil in the auxiliary engine oil tank is consumed, and insufficient lubrication, abrasion and the like caused by insufficient engine oil quantity are avoided.
Otherwise, continuing to perform automatic engine oil compensation, specifically comprising: if the length of time T of the automatic engine oil compensation 2 < second preset duration t 2 And, an oil level value L Supplement device If the value is less than the second preset liquid level value, controlling the auxiliary engine oil tank to continue to perform automatic engine oil compensation on the engine; duration T illustrating automatic engine oil compensation 2 Illustrating the duration T of the automatic compensation 2 Has not reached the second preset time t 2 And the oil level value L obtained in real time Supplement device If the level value does not reach the second preset level value, continuously acquiring the level value L of the main engine oil tank Supplement device Until the time length T of automatic engine oil compensation 2 Not less than the second preset time t 2 Or the oil level value L Supplement device And the value is not less than the second preset liquid level value.
If the duration T of automatic engine oil compensation 2 < second preset duration t 2 And, an oil level value L Supplement device If the value is larger than or equal to the second preset liquid level value, controlling the auxiliary engine oil tank to stop performing automatic engine oil compensation on the engine; illustrating the auto-compensation duration T 2 Illustrating the auto-compensation duration T 2 Has not reached the second preset time t 2 And the oil level value L obtained in real time Supplement device And when the second preset level value is reached, the engine oil in the engine oil tank reaches the normal use standard, the electromagnetic valve of the auxiliary engine oil tank is controlled to be closed, the engine oil is stopped from being supplied to the engine oil tank, and the engine oil is continuously supplied to the engine by the engine oil tank.
It should be noted that the second preset time period t 2 The time length of the engine oil from the first preset level value to the second preset level value is longer than. Therefore, the second preset time period t 2 Must be longer than the oil compensation duration. Therefore, the completion of oil compensation is ensured.
Specifically, the first preset time length T 1 Duration of automatic compensation T 2 A second preset time t 2 The first preset level value and the second preset level value can be automatically adjusted according to the type of the engine and the arrangement of the whole vehicle, and therefore the first preset duration T is achieved by the aid of the method 1 Duration of automatic compensation T 2 A second preset time t 2 The actual parameter ranges of the first preset level value and the second preset level value are not limited, and all the actual parameter ranges can reach the corresponding setting of the effect of the embodiment.
It should be noted that, during the first preset time period T 1 After the end, the preset time length is the first preset time length T 1 Oil level value L of oil tank acquired for multiple times n All of the oil level values L as a determination of whether to auto-compensate the engine oil n (i.e., after completion, the first preset duration T 1 And clearing all the engine oil level values obtained internally). Therefore, the oil level value which is used as one of conditions for judging whether to carry out automatic engine oil compensation can be free from the influence of bumping and the like as much as possible, so that the control is more accurate, and the next period (and the reset first preset time length T) are ensured 1 ) The obtained engine oil level value is accurate.
A500-horsepower diesel engine is assembled on a certain heavy truck, the normal capacity of an oil sump is 30L, and according to the requirement of the engine, the upper limit of the engine oil capacity is 35L and the lower limit is 25L; install a level sensor on engine oil pan for gather the interior machine oil liquid level of engine oil pan, simultaneously, first preset level value is 27L, and the second is set for the level value and is 33L, and time T is long when first presetting 1 The following settings are set: 2min, the time for replenishing 6L of engine oil for the heavy truck engine is about 3min (namely the time length T of automatic compensation) 2 Is 3 min);
it should be noted that, in this embodiment, 27L is selected as the first set level value, so as to ensure that the engine does not fail due to the lack of oil in the liquid level when the system is not replenished with oil in time; and 33L is selected as a second liquid level set value, so that excessive engine oil is filled in the automatic engine oil supplementing process.
If the oil level value L is within 2min, all the obtained oil level values L n When the volume is less than 27L, the electromagnetic valves are controlled to be opened, and the engine oil is automatically supplemented to the engine oil tank;
if the obtained oil level of a certain engine is more than 27L within 2min, presetting time length T for the first time 1 Clearing the internal engine oil level (namely clearing the data of the previous 2 min); in the process of automatic engine oil compensation, in order to prevent excessive refueling, when the engine oil liquid level L is obtained Supplement device And when the pressure is more than 33L, the electromagnetic valve is controlled to be closed, and the automatic compensation is finished.
