It should be understood that the preferred embodiments are presented by way of illustration only and not by way of limitation.
It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present invention by way of illustration, and only the components related to the present invention are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.
In a first aspect, referring to fig. 1 to 6, an embodiment of the present invention proposes an engine ignition control apparatus, including a main control module 1, an ignition control module 2, and a first number of ignition assemblies 3, where the first number of ignition assemblies 3 respectively correspond to a first number of cylinders, each of the ignition assemblies 3 includes a second number of ignition coils 31 and a second number of ignition plugs 32, each of the second number of ignition coils 31 is electrically connected to the second number of ignition plugs 32, and each of the first number and the second number is greater than or equal to 2; the main control module 1 is used for sending an ignition control signal for a cylinder to be ignited to the ignition control module 2, the ignition control module 2 is used for receiving the ignition control signal and controlling a second number of ignition coils 31 in an ignition assembly 3 corresponding to the cylinder to be ignited to discharge simultaneously according to the ignition control signal, so that the second number of ignition plugs 32 ignite simultaneously.
Specifically, the engine ignition control device provided by the embodiment of the invention is applied to automobiles, and the automobiles can be various automobile types, such as sedans, business cars, off-road vehicles or sport utility vehicles. The vehicle includes an engine including a first number of cylinders.
The main control module 1 may be an ECU or PDCU (Powertrain Domain Controller, power domain controller). The main control module 1 is electrically connected with the ignition control module 2, and the ignition control module 2 can be a single chip microcomputer or the like.

The second number may be three, i.e. the ignition assembly 3 comprises three ignition coils 31 and three spark plugs 32, i.e. the three ignition coils 31 and the three spark plugs 32 are used together for ignition of a single cylinder.
When the first number is four and the second number is three, the engine ignition control device includes twelve ignition coils 31 altogether, referring to fig. 1, the main control module 1 is electrically connected with the ignition control module 2 through four control lines 5, and the ignition control module 2 is electrically connected with the twelve ignition coils 31 through twelve connection lines respectively, that is, the ignition control module 2 can expand four-way input into twelve-way output.

When the first quantity is four, the engine comprises four cylinders, the four cylinders are a first cylinder, a second cylinder, a third cylinder and a fourth cylinder respectively, and the ignition sequence of the four cylinders is the first cylinder, the third cylinder, the fourth cylinder and the second cylinder in sequence. The cylinder to be ignited may be any one of four cylinders. Taking a cylinder to be ignited as a first cylinder as an example, the main control module 1 sends an ignition control signal for the first cylinder to the ignition control module 2, and the ignition control module 2 receives the ignition control signal and controls the second number of ignition coils 31 in the ignition assembly 3 corresponding to the first cylinder to discharge simultaneously according to the ignition control signal, so that the second number of ignition plugs 32 in the ignition assembly 3 corresponding to the first cylinder ignites simultaneously.

When the first number is four, the ignition control module 2 includes a processing unit 21 and four distribution units 22, the four distribution units 22 respectively correspond to the four ignition modules 3, and the four distribution units 22 respectively correspond to the four cylinders. The timing of the ignition execution signal is different from the timing of the ignition control signal, and the timing of the high level in the specific ignition execution signal is different from the timing of the high level of the ignition control signal. The timing of the ignition execution signal is advanced to the timing of the ignition control signal, and the advanced time is the preset delay compensation value.
