Problems solved by technology

[0003] During the operation of light-duty vehicles using the far rear injection regeneration technology, part of the diesel oil will adhere to the cylinder wall and mix into the oil in the main oil passage through the gap between the cylinder wall and the piston, which increases the dilution rate of the oil in the main oil passage. , affect the lubricity of the engine oil and the service life of the engine oil. Long-term use will cause the risk of cylinder scuffing, which will shorten the oil change interval of the engine oil and affect the performance of the diesel engine.

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] This application provides a control system for reducing the oil dilution rate of the engine system, so as to realize the volatilization of diesel oil mixed in the oil by increasing the temperature of the oil in the oil-gas separator, and reduce the dilution rate of the engine oil, so as to avoid the excessive dilution rate of the engine oil, resulting in poor lubricity of the engine oil. Reduced service life, short oil change intervals, high risk of long...

Abstract

The invention provides a control system and method for reducing the engine oil dilution rate of an engine system. The system comprises an electronic control unit and an intelligent heater arranged in an oil-gas separator in the engine system. The intelligent heater is in communication connection with the electronic control unit; the intelligent heater is used for detecting the temperature of engine oil in the oil-gas separator and heating the engine oil in the oil-gas separator according to a control instruction issued by the electronic control unit; the electronic control unit is used for issuing a control instruction to the intelligent heater according to the operation condition of an engine system and engine oil temperature data, diesel oil mixed into engine oil in the oil-gas separator can be volatilized, the engine oil dilution rate is reduced, and the situation that the engine oil dilution rate is too high is avoided. The oil change period is short; the risk of long-term use is high; and the performance of the diesel engine is reduced.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a control system and method for reducing the oil dilution rate of an engine system. Background technique [0002] At present, the active regeneration of the National VI DPF (diesel particulate filter, particulate matter trap) mainly includes: the active regeneration of the seventh injector and the regeneration of the remote injection in the sampling cylinder. Most medium and heavy diesel engines use active regeneration of the seventh injector, while light vehicles mostly use remote rear injection regeneration. [0003] During the operation of light-duty vehicles using the far rear injection regeneration technology, part of the diesel oil will adhere to the cylinder wall and mix into the oil in the main oil passage through the gap between the cylinder wall and the piston, which increases the dilution rate of the oil in the main oil passage. , affect the lubricity of the engine oi...
