Description

Oil regulator for two-stroke IC engine

Technical Field

The utility model relates to a two-stroke internal-combustion engine field, concretely relates to two-stroke internal-combustion engine oil adjusting device.

Background

An engine oil compression pump is not arranged in the conventional two-stroke internal combustion engine to lubricate the engine, fuel oil and engine oil need to be prepared in advance in proportion before the two-stroke internal combustion engine works, but the phenomenon that the proportion of mixed liquid is not accurately prepared or the prepared mixed liquid is deteriorated after being placed for a long time often occurs because of the error of a measuring tool, so that the working state of the engine is not good, and the working efficiency is influenced.

In order to solve the above problems, CN102679123A discloses an invention named as an engine oil compression pump, which includes a base, a pump sheet, a gasket and an upper cover, and is characterized in that: a base is provided with an oil inlet pipe, an oil storage hole I, an oil storage hole II, an oil storage groove, a movable spring in the oil storage groove, an oil storage hole III, an oil storage hole IV and an oil outlet pipe, wherein the oil inlet pipe is communicated with the oil storage hole I, the oil storage hole II is communicated with the oil storage groove, the oil storage groove is communicated with the oil storage hole III, and the oil storage hole IV is communicated with the oil outlet pipe through channels respectively; b, placing a pump piece on the base, wherein an oil inlet separation blade and an oil outlet separation blade are arranged on the pump piece, and the oil inlet separation blade and the oil outlet separation blade respectively correspond to the second oil storage hole and the fourth oil storage hole; the gasket is arranged on the pump sheet and below the upper cover, and the cover body of the upper cover is provided with an air inlet hole.

Although the engine oil compression pump can realize independent engine oil supply of the two-stroke internal combustion engine and the engine oil finally coming out of the oil outlet pipe can be prepared and mixed with fuel oil according to the proportion, the following defects still exist:

Because the mixture of the engine oil and the fuel oil in the two-stroke internal combustion engine finally enters the combustion chamber to be burned together, and the engine oil also needs to play a lubricating role in the combustion process, in the combustion process of the engine oil, the poor atomization effect of the engine oil can cause the insufficient combustion phenomenon of the engine oil molecular group due to the higher physical aggregation state, the engine oil which can not be fully combusted can not provide combustion power and can not participate in the lubrication, and the cylinder pulling probability of the internal combustion engine can be increased due to the too little engine oil which participates in the lubrication; in order to reduce the cylinder-pulling probability of the internal combustion engine, the lubrication of the internal combustion engine by the engine oil can be ensured only by increasing the engine oil amount of the mixture of the engine oil and the fuel oil, so that the loss amount of the engine oil compression pump is large; in addition, insufficient combustion of the engine oil can cause the engine to run with high smoke.

2. The engine oil finally coming out of the oil outlet pipe is always constant, so that the cylinder pulling probability of the internal combustion engine is high or the waste amount of the engine oil is large. If the engine oil is prepared according to the engine oil consumption under the conditions of low temperature or normal temperature, the phenomenon of cylinder scuffing of the two-stroke internal combustion engine under the condition of high temperature is easy to occur due to insufficient engine oil lubricating quantity; if the engine oil is prepared in accordance with the amount of engine oil consumed at a high temperature, a large amount of unnecessary engine oil is wasted at a low temperature or a normal temperature in the two-stroke internal combustion engine.
