Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
The operation of the injector has the characteristic of a minimum response time, i.e., if the injector actuation time is less than the minimum response time, the injector is unable to open. If the oil injection quantity is the same, the oil injection pressure is increased, and the driving time of the oil injector is correspondingly shortened, so that the shortest response time characteristic of the oil injector can lead to the condition that the oil injector can realize multiple injection to be changed into single injection. For example, at a certain injection pressure value, the injector driving time is 2t, at this time, the injector can realize two injections, and if the injection pressure value is increased, the injector driving time will be less than 2t, in which case the injector can only realize a single injection. The multi-injection strategy ensures that the injected gasoline has better atomization effect, more sufficient oil-gas mixture and better particulate emission control, so the inventor thinks that corresponding target oil injection pressure values can be calculated according to different oil injection amounts, and the aim is to increase the oil injection time, realize more positive multi-injection and fully utilize the multi-injection to use high-pressure injection.
Fig. 1 is a flowchart of an oil pressure control method for a direct injection engine provided by an exemplary embodiment. As shown in fig. 1, the method may include the steps of:
Step S11, when the vehicle is running, the target oil injection quantity of the oil injector is obtained. In the related art, the target injection amount of the injector may be calculated according to the operating condition of the engine.
Step S12, determining a fuel injector driving time corresponding to both the target fuel injection amount and the predetermined minimum fuel injection pressure value. The minimum injection pressure value is the minimum value of the pressure required by the system of the engine and the injector to inject fuel, and can be provided by a supplier and is a fixed value. As previously described, the fuel injection pressure value and the fuel injector actuation time have an inverse relationship, i.e., the smaller the fuel injection pressure value (which is greater than the predetermined minimum fuel injection pressure value), the greater the fuel injector actuation time. Thus, the predetermined minimum fuel injection pressure value corresponds to the maximum value of the injector driving time, with the target fuel injection amount being determined unchanged.
Step S13, determining target driving time according to the determined driving time of the fuel injector. The injector driving time determined according to the above-described step S12 is the maximum value of the possible driving times, and on the basis of the determined injector driving time, the target driving time can be obtained with a slight adjustment in terms of its rationality and operability. The target driving time is the time for which the fuel injector is expected to actually perform fuel injection, and is relatively close to the maximum value of the driving time which can be realized, so that the number of fuel injection times is relatively large.
And S14, determining a target oil injection pressure value of the oil injector according to the target driving time and the target oil injection quantity. In order to achieve the target drive time, the determined target injection quantity can be completed with an appropriate injection pressure value, which is regarded as the target injection pressure value.
In step S15, the fuel injector is controlled to inject fuel according to the target fuel injection pressure value.
According to the technical scheme, the driving time of the fuel injector corresponding to the target fuel injection quantity and the preset minimum fuel injection pressure value is determined, the target driving time is determined according to the determined driving time of the fuel injector, and the target fuel injection pressure value of the fuel injector is determined according to the target driving time. Therefore, the target oil injection pressure value of the oil injector can be flexibly and reasonably determined in real time, so that the target oil injection pressure value is smaller, and the driving time of the oil injector is prolonged. As the oil injection time is increased, more positive multiple injection is realized, and the emission of particulate matters during the running of the engine is reduced.
In still another embodiment, the step S12 of determining the injector driving time corresponding to both the target fuel injection amount and the predetermined minimum fuel injection pressure value may include:
determining a fuel injector actuation time corresponding to both the target fuel injection amount and the predetermined minimum fuel injection pressure value according to the following equation:
Tmax=A0*Q1+B (1)
Where Tmax is the injector drive time corresponding to both the target injection amount and the predetermined minimum injection pressure value, Q 1 is the target injection amount, a 0 is the first coefficient corresponding to the predetermined minimum injection pressure value, and B is the predetermined second coefficient.
Wherein, there is a predetermined correspondence between the injection pressure value and the first coefficient, which can be obtained in advance according to a test. And A 0 is a first coefficient corresponding to a preset minimum fuel injection pressure value, which is searched from the corresponding relation.
In this embodiment, the correspondence between the injector driving time and the injection amount is applied:
T=A*Q+B (2)
Wherein T is the driving time of the fuel injector, Q is the fuel injection quantity, A is a first coefficient corresponding to the fuel injection pressure value, and the unit can be seconds/gram. B is a predetermined second coefficient, and may be in seconds. That is, through experiments, a corresponding array of the driving time T, the fuel injection quantity Q and the fuel injection pressure value C of the fuel injector is obtained, T, Q when B and C are equal are brought into the formula (2) to be fitted, and a corresponding first coefficient a and a corresponding second coefficient B are obtained, wherein the first coefficient a is the first coefficient corresponding to the C. And similarly, obtaining A corresponding to different C, namely obtaining the preset corresponding relation between the oil injection pressure value and the first coefficient.
Then, returning to the embodiment of the formula (1), the known injection quantity is the target injection quantity Q 1, the predetermined minimum injection pressure value is known, and the first coefficient a 0 corresponding to the predetermined minimum injection pressure value is obtained according to the correspondence relation, and the second coefficient B is known. The injector driving time Tmax corresponding to both the target injection amount Q 1 and the predetermined minimum injection pressure value, which is the maximum driving time (i.e., injection time) at which the target injection amount Q 1 can be theoretically achieved, is calculated according to the formula (1) because the minimum injection pressure value is corresponding.
In still another embodiment, the step S13 of determining the target driving time according to the determined injector driving time may include:
if Tmax > m×t 0, determining the target driving time to be m×t 0, where M is a predetermined positive integer, and T 0 is the shortest response time of the injector;
If n×t 0>Tmax>(N-1)*T0, the target driving time is determined to be (N-1) ×t 0, where N is a positive integer, and N < M.
Where M is the maximum number of injections that can be achieved, and may be predetermined to be a fixed value depending on the driving capabilities of the injector and the engine control unit. T 0 is a fixed value.
In this embodiment, if the injector driving time determined in step S12 is not an integer multiple of T 0, the determined injector driving time is rounded according to T 0, and then a target injection pressure value is calculated according to the rounded injector driving time (target driving time) and the target injection quantity, so as to reduce the emission of particulate matter by high-pressure injection. If the injector driving time determined in step S12 is exactly an integer multiple (less than or equal to M) of T 0, the injector driving time determined in step S12 is directly taken as the target driving time. In this way, the injector drive time can be maximized, thereby greatly reducing particulate emissions.
In yet another embodiment, the method may further include determining that the target fuel injection pressure value of the fuel injector is a preset minimum fuel injection pressure value if T 0 is greater than or equal to Tmax.
That is, if the driving time of the injector determined in step S12 is less than the shortest response time of the injector, the target injection pressure value may be directly determined as T 0, and the target driving time is not determined any more, so that it is ensured that the injection is performed.
In still another embodiment, the step S14 of determining the target injection pressure value of the injector according to the target driving time and the target injection quantity may include:
and determining a first coefficient corresponding to the target fuel injection pressure value according to T 1＝A1*Q1 +B. Wherein T 1 is a target driving time, Q 1 is a target injection quantity, and a 1 is a first coefficient corresponding to a target injection pressure value. Wherein, the oil injection pressure value and the first coefficient have a preset corresponding relation, and B is a preset second coefficient;
And searching an oil injection pressure value corresponding to A 1 in the corresponding relation between the oil injection pressure value and the first coefficient as a target oil injection pressure value.
That is, step S14 also calculates the target injection pressure value of the injector using the above-described formula (2). Knowing the target drive time T 1, the target fuel injection amount Q 1, and the predetermined second coefficient B, a first coefficient a 1 corresponding to the target fuel injection pressure value Q 1 is calculated according to the formula (2), and then the fuel injection pressure value corresponding to a 1 is found in the predetermined correspondence as the target fuel injection pressure value.
In the method, through constructing the formula (2) and the corresponding relation, the proper target oil injection pressure value is calculated in real time, so that the driving time of the oil injector is maximized, multiple injection is positively promoted, and the emission of particulate matters is greatly reduced.
