Automatic decompression starter

Abstract

The invention provides an automatic decompression starter, which relates to the field of electric starting technology of an internal-combustion engine and mainly comprises a power switch, an electromagnet and a starter. The automatic decompression starter is characterized in that: the power switch consists of a moving contact and two static contacts; an iron core of the electromagnet is in clearance fit with a shifting fork and is fixedly connected with a pulling wire lined with an internal-combustion engine decompression mechanism; both two static contacts of the power switch are connected with the electromagnet and a power connection of the starter respectively; and both switch-on and switch-off of a power supply of the starter are later than those of the electromagnet. The starter works in the state of decompression so that the starting failures are greatly reduced and the service life is prolonged.

Description

technical field [0001] The automatic decompression starter of the invention relates to the technical field of electric starting of internal combustion motors, and the international classification number is F02N11 / 08. Background technique [0002] The starter used in the existing internal combustion engine is composed of an electromagnetic switch and a starter. The steps are as follows: the manual switch turns on the electromagnetic switch power supply—the iron core on the electromagnetic switch moves the shift fork to mesh the starter gear with the flywheel of the internal combustion engine—the electromagnetic switch conducts the power supply. Turn on the starter power supply - start the internal combustion engine. Such disadvantages are: large starting resistance, large starting current, many starting faults, short battery life and short motor life. This method has a shortcoming, it requires both hands to operate and cooperate with coordination, otherwise it is also prone ...

AI Technical Summary

Problems solved by technology

Such disadvantages are: large starting resistance, large starting current, many starting faults, short battery life and short motor life. The first method has a shortcoming, it needs to be operated with both hands and coordinated, otherwise it is prone to failure. In addition, some operators try to save trouble and start directly without operating the decompression device, which causes more failures.

The technical scheme of Chinese patent application 200810184272.6 overcomes the above technical shortcomings and achieves automatic decompression starting, but there are still deficiencies. After the power is turned off, the valve is closed, which reduces the reliability of starting
