Control method of reversal compressing power assisting starting equipment

Abstract

The invention discloses a control method of reversal compressing power assisting starting equipment. The control method adopts a starting motor enabling a crankshaft to positively rotate and negatively rotate, a first detecting mechanism for detecting the rotating direction of the crankshaft, a second detecting mechanism for detecting the rotating speed of the crankshaft and a control mechanism; the control mechanism drives an engine to negatively rotate firstly before the engine is started, air in an air cylinder is compressed, then the crankshaft is controlled to positively rotate, and the engine is started; and initial driving force of the crankshaft is increased through the pressure of the compressed air in the air cylinder. According to the control method of the reversal compressing power assisting starting equipment, the condition that the engine is started through the small torque motor is achieved.

Description

technical field [0001] The invention relates to a control method of a starting device, in particular to a control method of a reverse compression booster starting device. Background technique [0002] When the starting mechanism of the engine is designed to use the generator as the starter motor (ACG motor), since the volume of the ACG motor is limited by the volume of the engine, it cannot be enlarged, so the starting torque of the ACG motor is small, and the starting torque of the ACG motor is relatively small. The resistance of the compression stroke of the four-stroke engine is relatively large. It is difficult for this ACG motor to turn over the compression stroke at the beginning of starting. Therefore, in order for the ACG motor to overcome the resistance of the compression stroke, additional power is required to make up for it when starting. In view of the lack of torque of the ACG starter motor, in view of the above expectations, an engine starting device is innovat...

[0002] When the starting mechanism of the engine is designed to use the generator as the starter motor (ACG motor), since the volume of the ACG motor is limited by the volume of the engine, it cannot be enlarged, so the starting torque of the ACG motor is small, and the starting torque of the ACG motor is relatively small. The resistance of the compression stroke of the four-stroke engine is relatively large. It is difficult for this ACG motor to turn over the compression stroke at the beginning of starting. Therefore, in order for the ACG motor to overcome the resistance of the compression stroke, additional power is required to make up for it when starting. Insufficient torque of the ACG starter motor, in view of the above expectations, an engine starting device is innovated, which makes up for the lack of torque of the ACG motor
