Problems solved by technology

Artificially increase i, after the primary energy storage increases, the energy coupled to the secondary increases, and the secondary energy increases, mainly due to the increase in the secondary current. In the secondary ignition circuit, the secondary current increases due to the large DC resistance. It also increases the loss of the DC resistance, which is proportional to the square of the current, that is to say, most of the increased energy is consumed by the DC resistance, and the spark energy at the spark plug gap increases very little, so the existing ignition system Ignition spark energy does not increase significantly at the spark plug gap

Description

1. Technical field: [0001] The invention relates to an automobile ignition system, in particular to a novel automobile ignition system mainly aimed at automobiles with electronic fuel injection engines that have no carburetor and no distributor, and whose fuel injection and ignition are controlled by a computer. 2. Background technology: [0002] The ignition energy of the existing EFI vehicle (see Figure 1, mainly analyzing the energy of the dual-point ignition circuit): [0003] It can be seen from Figure 1 that the ignition system of the existing EFI vehicle is composed of a transistor igniter, an ignition coil, a high-voltage damping wire, and a built-in resistance spark plug. In this ignition system, the transistor igniter is an electronic switch that can be controlled by an external signal, and it determines whether the transistor T1 is turned on or off according to the external signal; the ignition coil is an energy storage and high voltage generation component, how m...
