Embodiment Construction
[0040] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0041] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0042] Refer below Figure 1-Figure 5 An engine supplementary air control method according to an embodiment of the present invention will be described. Such as figure 1 , figure 2 with Figure 4 As shown, the engine supplementary air control method implemented according to the present invention includes the following steps:
[0043] S1, collecting the engine working condition signal;
[0044] S2. According to the detection value of the engine working condition signal, it is judged whether the engine is in an acceleration condition. If the engine is in an acceleration condition, the air supply device 200 and the exhaust gas recirculation device 100 of the engine are triggered to suppl...

The invention discloses an engine air-supplying control method. The method comprises the following steps of (S1) collecting an engine work condition signal, (S2) determining whether an engine is at an accelerating work condition according to a detection value of the engine work condition signal, and (S3) determining whether the engine is at a stable work condition according to the detection value of the engine work condition signal. In the step 2, if the engine is at the accelerating work condition, an air supplying device and an exhaust recycling device of the engine are both triggered to supply air output by the air supplying device to the engine, and supply exhaust output by the exhaust recycling device to the engine, or the air supplying device is triggered to supply air output by the air supplying device to the engine. In the step 3, if the engine the at the stable work condition, the exhaust recycling device can be selectively triggered to supply exhaust to the engine. According to the engine air-supplying control method, different air supplying strategies are employed for different work conditions, so accurate control can be achieved.
Description
technical field [0001] The invention relates to the technical field of engines, in particular, to an engine supplementary air control method. Background technique [0002] In the related art, the air supply technology of the engine only controls the air supply, and there is knocking during the air supply process, so there is room for improvement. Contents of the invention [0003] In view of this, the present invention aims to propose a method for controlling air supplementation of the engine, which supplements at least one of air and exhaust gas according to the working conditions of the engine. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A method for controlling air supplementation of an engine, comprising the following steps: [0006] S1, collecting the engine working condition signal; [0007] S2. According to the detected value of the engine working condition signal, it is judged wheth...
