Problems solved by technology

However, on the one hand, this treatment scheme requires the design of a complex monitoring, control and separation system to separate the fuel from the engine oil, and its cost is relatively high; on the other hand, the absolute amount of separated fuel is not too high. Inexpensive compared to configuration costs of monitoring, control and separation systems

Abstract

The invention relates to an engine oil dilution improvement device. The device comprises an oil collection ring (10) used for scraping and collecting wall-attached fuel oil and an electronic control valve (11) sucking the collected fuel oil from the oil collection ring (10), wherein the oil collection ring (10) is arranged on the wall of a piston, so that the wall-attached fuel oil is collected inthe oil collection ring (10) before flowing into an oil sump, and the electronic control valve (11) sends the collected fuel oil back to a cylinder for re-combustion. Through the technical scheme ofthe engine oil dilution improvement device, the probability that the wall-attached fuel oil is mixed into the oil sump can be reduced fundamentally and even eliminated, the dilution degree of engine oil is directly and effectively reduced, and the purpose of optimizing engine oil dilution is achieved.

Description

technical field [0001] The present invention relates to a device for improving oil dilution and, more particularly, to a device for improving oil dilution by returning Coanda fuel to the cylinder and reburning it before it flows into the sump. Background technique [0002] Engine oil, that is, lubricating oil in automobile engines, has important functions such as cleaning, lubrication, sealing, and heat dissipation. Therefore, the oil in a car engine is as important as blood in a human body. When the engine is in a cold start, high speed and high load state, the fuel is prone to poor atomization. In this case, droplets of fuel adhere to the cylinder walls, then seep into the crankcase and flow into the oil sump, where they end up in the engine oil, causing it to become diluted. This phenomenon is especially evident in direct-injection engines due to insufficient atomization time and space conditions. [0003] Too much dilution of the engine oil can cause adverse consequen...
