Abstract

The invention discloses a low-pass filtering based engine fuel consumption detection system, mainly comprising a single-chip microcomputer (1), a power platform to be detected, an engine to be detected, a measuring and controlling instrument (4), a power analyzer (2), an accelerator driver (5), a motor controller (3), a fuel signal acquisition system (6), and a low-pass filtering system (7). The engine is disposed on the power platform. The measuring and controlling instrument (4) and the power analyzer (2) are connected with the single-chip microcomputer (1). The accelerator driver (5) is connected with the power analyzer (2). The fuel signal acquisition system (6) is connected with the engine. The input end of the low-pass filtering system (7) is connected with the fuel signal acquisition system (6), and the output end thereof is connected with the single-chip microcomputer (1). The system is capable of processing acquired signals, the processed signals are of high fidelity, and thus precision of the system is improved.

Description

technical field [0001] The invention relates to the field of engine testing, in particular to an engine fuel consumption detection system based on 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 of fuel cons...
