For example, in the field of engines for vehicles, with the great trend of energy conservation and environmental protection, the oil consumption of the engine is an important influence factor of the engine, especially an important link in the development and design process of the engine. The oil consumption of the engine directly affects the continuous safe operation of the engine and the emission performance and service life of the engine, so that it is very important to accurately and conveniently test the oil consumption of the engine in the development and test process.
The existing engine oil consumption measuring method adopts an oil discharging and weighing method, namely 1) adding engine oil into an engine from an engine oil filling port by using a funnel, operating the engine to fill an oil duct of the engine with the engine oil, and adding the engine oil to the upper limit position of an engine oil scale through multiple times of addition; 2) and (4) putting the engine oil in the engine into the oil containing basin from the oil drain hole of the oil pan, and screwing down the oil drain hole. The mass of the oil in the oil pan is manually weighed on an electronic scale and this portion of oil is added back to the engine. In the process, if the engine oil overflows, the overflowing engine oil is wiped clean by using a clean non-woven fabric and weighed. Calculating the mass difference of the oil basin, the funnel and the non-woven fabric to obtain the initial net mass M1 of the engine oil added into the engine; 3) and operating the engine according to a set working condition, and replenishing the oil according to the oil dipstick during the operation of the engine.
