Abstract

The invention discloses an engine oil consumption detecting system based on four-order low-pass filtering processing. The engine oil consumption detecting system mainly comprises a single chip microcomputer (1), a tested power platform, a tested engine arranged on the tested power platform, a measurement and control instrument (4) and a power analyzer (2) connected with the single chip microcomputer (1), an accelerator driver (5) connected with the measurement and control instrument (4), a motor controller (3) connected with the power analyzer (2) and a fuel oil signal collecting system (6) connected with a tested motor. The measurement and control instrument (4) is connected with the tested motor. The engine oil consumption detecting system is characterized in that a four-order low-pass filtering processing system (7) is arranged between the fuel oil signal collecting system (6) and the single chip microcomputer (1), the four-order low-pass filtering processing system can carry out complete filtering processing on collected signals, interference from the outside on the signals is avoided, and the accuracy of the oil consumption detecting system is improved.

Description

technical field [0001] The invention relates to the field of engine testing, in particular to an engine oil consumption detection system based on fourth-order low-pass filter processing. Background technique [0002] People's requirements for the reliability, safety and greenness of automobiles are constantly increasing, and the engine is the heart of the automobile, and its technical level directly affects its performance indicators such as power, economy, and emissions. The frequency of engine failure It is also the highest. The engine comprehensive performance test is the main means to judge the technical condition of the engine, and it is also an important part of the vehicle inspection and maintenance work. Therefore, the engine performance test has been paid more and more attention by people. In addition, the fuel consumption is an important index to evaluate the engine economy and one of the important measurement parameters of the engine. Therefore, the measurement ...
