Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0009] Such as figure 1 As shown: the present invention includes a power supply 1, a controller 2, a speed detection module 3, a debugging module 4 and an engine 5.

[0010] Such as figure 1 As shown: the power supply terminal of the engine 5 is connected to the power supply 1 through the controller 2, and the power supply 1 is used to provide the working power of the engine 5; the controller 2 includes a single chip microcomputer, and the input terminal of the controller 2 is also connected to the speed detection module 3. The speed detection module 3 is used to detect the rotational speed of the engine 5 , and the engine 5 has different starting rotational speeds according to different usage environments of the engine 5 . The starting speed range is preset in the controller 2. When the speed detection module 3 detects that the speed of the engine 5 reaches ...

Abstract

The invention relates to an engine secondary ignition protection structure which comprises an engine, wherein a power end of the engine is connected with a power supply through a controller, and the power supply is used for providing working power for the engine; an input end of the controller is connected with a speed detection module used for measuring the rotation speed of the engine; after the rotation speed of the engine reaches a set value, the controller cuts off the connection between the power supply and the engine. When the structure provided by the invention is started, the power supply provides working power for the engine, and after the rotation speed of the engine reaches the set rotation speed, the controller cuts off the connection between the power supply and the engine, thereby avoiding secondary ignition after the engine is started, guaranteeing the operation safety after the engine is started, and prolonging the service life of the engine; the controller is connected with a debugging module, and can connect the power supply and the engine through the debugging module; and the structure is applied to the maintenance and push start, is simple and compact, convenient to install and use, safe and reliable, and reduces the using cost.

Description

technical field [0001] The invention relates to a protective structure, in particular to an engine secondary ignition protection structure, which belongs to the technical field of engine protection. Background technique [0002] The life of the passenger car starter motor is limited, and if it is used improperly, the service life will be shortened. When the mechanical and electrical components of the vehicle are running well, the most likely cause of shortening the life of the starter motor is that the engine is still running and the ignition is re-ignited. Accompanied by severe mechanical noise, the damage caused is huge. With the maturity of today's engine technology and the improvement of sound insulation technology for passenger cars, it sometimes seems difficult to tell whether the engine is running or not by sound. Although most vehicles now have a signal prompt when the engine is not started, it is generally a light signal, which is easy to be ignored; occur. Cont...
