TCI igniter circuit with speed limiting function

Abstract

A TCI igniter circuit with a speed limiting function comprises an ignition control circuit and an ignition coil. The two ends of the ignition coil are connected with a flame-out line and a GND end correspondingly. The TCI igniter circuit further comprises a flame-out controller. The acquisition end of the flame-out controller is connected with the flame-out line through a speed acquisition circuit. The control end of the flame-out controller is connected with the input end of the flame-out control circuit. An output end set of the flame-out control circuit is connected with the two ends of the ignition coil correspondingly. The TCI igniter circuit with the speed limiting function is simple in overall structure; and under unified coordination of the flame-out controller, the rotating speed situation of an engine is precisely monitored in real time through a speed acquisition circuit, automatic flame-out control is achieved after the rotating speed gets ultrahigh, ignition control and speed limiting control are effectively integrated, the circuit is simplified, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of general gasoline control, in particular to a TCI igniter circuit with speed limiting function. Background technique [0002] In order to ensure the safe operation of the engine, the igniter is required for speed limit control when the engine is overspeed. The existing ignition circuit has a complex structure and single function, and often only has the ignition control function. The speed limit control requires a special circuit to realize, which greatly increases production. The cost reduces the market competitiveness of the product, and the existing ignition control circuit consumes a lot of energy, and the control is not precise. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a TCI igniter circuit with a speed limiting function that is simple in structure, diverse in functions, and integrates ignition control and speed limiting control.
