Abstract

The invention discloses a main machine apparatus for testing the lubricating performance of fuel oil. The main machine apparatus comprises a vibration exciter, a main shaft connector, a shaft rod assembly, a test apparatus and a heating and measuring apparatus, wherein the main shaft connector is arranged on one end of the vibration exciter and used for making reciprocating movement under the effect of the vibration exciter; one end of the shaft rod assembly is connected with the main shaft connector; the test apparatus comprises a test part, a test sheet and an oil box, the test sheet is arranged on the inner bottom of the oil box, one end of the test part is accommodated in the oil box and presses the test sheet, and the other end of the test part is connected with the other end of the shaft rod assembly; and the heating and measuring apparatus is used for supporting the oil box, the oil box is used for accommodating a fuel oil sample, and the heating and measuring apparatus is usedfor heating the oil box and detecting the vibration of the oil box. By adopting the main machine apparatus, the lubricating performance of the fuel oil can be detected, the operation is simple, and the test result is objective and accurate.

Description

technical field [0001] The present application relates to the field of fuel testing, in particular to a host device for measuring the lubricity of fuel, more specifically, to a host device for testing the lubricity of gasoline and diesel. Background technique [0002] Due to the lighter components of gasoline and the lower kinematic viscosity, gasoline does not have good lubricating properties. In recent years, in order to solve the two major problems of fuel saving and emission reduction, new environmental protection regulations have been continuously introduced, and gasoline is subject to stricter restrictions than diesel. Not only must exhaust emissions meet standards, but the volatility, impurity content, and chemical composition of newly formulated gasoline are all restricted by new regulations. The content of polar impurities, aromatics, and olefins in gasoline is gradually reduced. On the other hand, since conventional injection gasoline engines are gradually replace...
