A control method, device and system for an electronic balance shaft of an engine

Abstract

The invention relates to a method, device and system for controlling an electronic balance shaft of an engine. The method includes: locking the phase of the balance shaft and the phase of the crankshaft when the engine is installed; phase signal and the first crankshaft phase signal; judge whether the two are consistent; if they are not consistent, adjust the phase of the balance shaft through the drive motor to make the phase of the balance shaft and the crankshaft consistent; when the engine is working, check the phase of the balance shaft and the crankshaft Phase difference compensation; after the engine is turned off, obtain the phase signal of the second balance shaft and the phase signal of the second crankshaft through the sensing device; judge whether the two are consistent; if they are inconsistent, adjust the phase of the balance shaft by driving the motor to make the balance shaft and The phases of the crankshaft are consistent, and the invention can adjust the balance shaft by driving the motor, so that the phases of the balance shaft and the crankshaft are consistent, and the balance and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a method, device and system for controlling an electronic balance shaft of an engine. Background technique [0002] The combustion pressure of the engine is output externally through the crank connecting rod mechanism. When the crank connecting rod mechanism is working, due to the uniformity of combustion of each cylinder and the rigidity of the shafting itself, the engine produces abnormal vibration when it is working. In order to ensure the balance of the engine when it is working, a balance shaft system is added to the engine. The balance shaft system can effectively solve the abnormal vibration of the engine during operation caused by the imbalance of the crankshaft itself. At the same time, the balance shaft system needs to be effectively driven to ensure that it is in phase with the crankshaft. [0003] At present, the common driving methods include gear drive and chain ...

AI Technical Summary

Problems solved by technology

[0003] At present, the common driving methods include gear drive and chain drive. Although the common driving methods ensure that the phase of the crankshaft and the balance shaft are consistent, they also bring noise problems from the gears and chains, and driving the balance shaft also consumes the output of the crankshaft. achievement

[0004] At present, resin gears or rubber gears have been developed to solve the gear noise problem in domestic and foreign markets. These gears can effectively reduce the noise problem of gear transmission, but cost and reliability are still a big problem.
