Stepless variable engine signal panel tooth number electronic converter

Abstract

The invention discloses a stepless variable engine signal panel tooth number electronic converter. The stepless variable engine signal panel tooth number electronic converter comprises a sensor whichis set on a side face of a flywheel or a signal panel and is used for detecting the passing tooth number of the flywheel (or the signal panel) in unit time; and a tooth number electronic converter ofwhich input end is connected with a sensor through a signal line, and output end is connected with the input end of a full vehicle instrument. The tooth number electronic converter comprises a PLC module and a debugging calibration board. The PLC module is equipped with a high speed counting module and a tooth number ratio (tooth ratio for short) parameter setting module. The high speed counting module carries out high speed counting on the engine tooth number. Through calculation of the tooth ratio parameter setting module, the engine tooth number required by the full vehicle instrument is finally output. According to the stepless variable engine signal panel tooth number electronic converter, under the condition of not changing a new engine state and instrument parameters, any tooth number conversion is realized, and the replacement cost is reduced.

Description

technical field [0001] The invention relates to the field of engines, in particular to an electronic converter with infinitely variable number of teeth on a signal disc of an engine. Background technique [0002] At present, the domestic engine development and manufacturing technology has developed to a certain extent. The domestic engine is basically comparable to the imported engine in terms of performance, emission and reliability, but it has a great advantage in price, and it also has product type. Complete spectrum, convenient maintenance parts and timely service and other advantages. Compared with domestic engines, the maintenance cost of imported engines is often more expensive than the replacement of new domestic engines. Therefore, most users currently use domestic engines to replace them when the original imported engines have serious failures or reach the level of scrapping. [0003] Each engine needs to output its current operating state to external equipment, i...

AI Technical Summary

Problems solved by technology

[0008] Disadvantages: Importing complete vehicles and replacing their engines, manufacturers generally do not authorize modifications

[0011] Disadvantages: The state of the original machine has been changed. Since it must be associated with the crankshaft / camshaft and connected reliably, there may not be a suitable installation point

[0014] Disadvantages: Due to the small quantity of replacement machines, the manufacturing cost is high, and the production cycle is long

In addition, the design of the flywheel needs to consider the transfer inertia, dynamic balance and other issues of the whole machine. Random changes will have a certain impact on the performance of the original engine, and it must be done by the engine manufacturer, and ordinary users or dealers cannot do it.
