[0064] Based on the above-mentioned first embodiment, the engine control method of this embodiment, in the step S20, includes:
[0065] Step S21: When the engine water temperature is lower than the reference water temperature and the engine shutdown time is a preset time, determine that the target operation mode is the first operation mode; wherein, the first operation mode is to control the engine according to the catalytic converter heating mode Enter the energy supplement mode after running for the first time, and control the engine to enter the standard working mode after running in the energy supplement mode for the second time;
[0066] It should be noted that the reference water temperature is a standard for measuring the engine water temperature. When the engine water temperature is lower than the reference water temperature, the engine first needs to run the catalytic converter heating mode to heat the temperature of the three-way catalytic converter to the target valu...

The invention belongs to the technical field of engines, and discloses an engine control method and device, a vehicle and a storage medium. The method comprises the steps that when an engine of the vehicle is controlled to be started, the engine water temperature and the engine stop time of the engine are obtained; according to the water temperature of the engine and the stop time of the engine, a target operation mode of the engine is determined, and the target operation mode comprises at least one of a catalytic converter heating mode, an energy supplementing mode and a standard working mode; and the engine is controlled to operate according to the target operation mode. Through the mode, whether the engine is in the hot state or the cold state is judged according to the water temperature and the stop time of the engine, and the corresponding target operation modes are determined according to different states of the engine, so that the engine operates according to the target operation modes. Therefore, the cold-state and hot-state cycle electric quantity balance and the cycle effectiveness of the whole vehicle can meet the requirements of laws and regulations during emission cycle detection.
Description
technical field [0001] The present invention relates to the technical field of engines, in particular to an engine control method, device, vehicle and storage medium. Background technique [0002] According to the requirements of the draft National VI emission standards for heavy-duty gasoline vehicles, hybrid heavy-duty gasoline vehicles will implement the National V standards from July 1, 2022, and the National VI standards from July 1, 2023. In addition to meeting the emission limit requirements of the National VI standard, the test cycle of the H-I type test must meet the requirements of the power balance, and at the same time ensure that the validity of the cycle meets the requirements of the regulations, otherwise the cycle test is invalid; because the discharge pretreatment before the H-I type test The cycle is a hot state cycle, and the official emission starts in a cold state and a hot state. Because there are differences in the energy flow of the engine in a cold s...
