Intelligent-type pre-lubricating system of engine

Abstract

The invention discloses an intelligent-type pre-lubricating system of an engine. The intelligent-type pre-lubricating system comprises an oil bottom shell and an engine lubricating system, wherein the intelligent-type pre-lubricating system is characterized by also comprising a pre-lubricating oil pump, a controller, a controller power supply module and a pressure sensor used for detecting oil pressure of an engine lubricating system; the inlet of the pre-lubricating oil pump is communicated with the oil bottom pump; the outlet of the pre-lubricating oil pump is communicated with an lubricating oil path of the engine lubricating system; the signal output end of the pressure sensor is electrically connected with the signal input end of the controller; and the controller starts the pre-lubricating oil pump while obtaining the power of the controller power supply module and controls the pre-lubricating oil pump to stop working according to a detecting result of the pressure sensor. According to the invention, the intelligent-type pre-lubricating system realizes to fill engine oil in a lubricating oil channel of the engine and avoids dry-type abrasion in an engine starting procedure; in addition, power consumption is also reduced on a condition of satisfying actual working condition demands of the engine.

Description

technical field [0001] The invention relates to an engine pre-lubrication system. Background technique [0002] With the continuous upgrading of automobile technology, the production process of the engine is becoming more and more precise, and the fit gap between the friction pairs in the engine is getting smaller and smaller, and maintaining the fit gap between the friction pairs is an important factor to ensure the long-term smooth operation of the engine. premise. Since no good solution has been found for the wear of engine parts, the stability and reliability of the engine have been directly affected. According to data, more than 90% of zero engine wear occurs within three minutes after cold start. If the lubrication of the engine during cold start can be effectively solved, the engine wear problem will basically be solved. [0003] The lubrication of the engine is mainly completed by the mechanical oil pump. The mechanical oil pump is driven by the crankshaft of the e...

AI Technical Summary

Problems solved by technology

The volume of this type of electric oil pump will be large, and the power of the motor will be high. The general heavy horsepower and small and medium horsepower engines cannot meet the installation space and battery specifications, and the control scheme and use are not perfect enough.

So far in China, there is no electric motor oil pump with suitable specifications for heavy horsepower and small and medium horsepower. In addition, the market's carrying capacity for medium and heavy vehicles continues to increase, so medium and heavy engines will become the main research and development object and development direction. In this development process, wear is a problem that must be solved
