Abstract

The invention discloses an engine oil online mixing device and method using the same. The device comprises an online monitoring unit, an analysis unit, a mixing unit and a control unit, wherein the online monitoring unit is used for measuring engine oil quality parameters in an oil sump of an engine in real time; the analysis unit is used for acquiring the engine oil quality parameter values measured by the online monitoring unit, analyzing the engine oil quality parameter values, and outputting a signal according to an analysis result; the mixing unit is used for injecting an engine oil additive into engine oil in the oil sump so as to mix the engine oil quality; and the control unit is used for receiving the signal sent by the analysis unit so as to control operation of the mixing unit.According to the device, the online monitoring unit and the mixing unit are combined into one associated device, the quality of engine oil in the oil sump in the working process of the engine is monitored in real time through the online monitoring unit, meanwhile, the mixing unit is used for completing addition work of the engine oil additive in the working process of the engine, shutdown checkingis not needed, and manual operation is avoided.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an engine oil online blending device and a method thereof. Background technique [0002] The engine is the heart of the car. There are many metal surfaces that rub against each other in the engine. These parts move fast and the environment is poor. The working temperature can reach 400°C to 600°C. The use of engine oil can effectively improve various problems that may occur during the working process of the engine. During the working process of the engine, the engine oil mainly has 1. Lubrication and wear reduction to prevent excessive wear between parts. 2. Cool down, the oil can bring heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine. 3. Cleaning and cleaning, the engine oil can bring the carbides, sludge, and worn metal particles on the engine back to the oil tank through the oil circuit to clean the surfa...
