Problems solved by technology

[0002] In the existing measurement of engine fuel consumption, due to factors such as the temperature change of the engine return oil and the gas contained in the return oil, measurement errors occur, and there are technical problems such as low measurement accuracy and large errors during measurement.
In addition, since the engine return oil contains a large number of air bubbles, when the engine return oil enters the engine again, the engine may not operate normally, or even cause the engine to stall, seriously affecting the life of the engine. Therefore, it is necessary to promptly discharge the gas contained in the engine return oil. the question is very critical

Abstract

The invention provides a compensation type oil consumption meter which comprises a flow measuring instrument and a closed tank. An oil return port and an oil outlet are formed in the walls of the tank, an automatic exhaust valve is arranged on the top of the tank, a check valve is connected with an outlet of the automatic exhaust valve, and an outlet of the flow measuring instrument is communicated with the tank. The compensation type oil consumption meter has the advantages that gas in backflow oil of an engine can be timely exhausted, so that measurement results can be prevented from being affected by oil temperature change and the gas in the backflow oil of the engine, and oil consumption of the engine can be conveniently and accurately measured; the compensation type oil consumption meter is simple in structure, convenient to maintain, low in machining cost, good in stability and high in measurement precision, and the like.
