The invention discloses an engine test and control system based on the high-speed dynamic response of engine emission. The engine test and control system mainly comprises a tested power platform and a tested engine arranged on the tested power platform. The engine test and control system is characterized in that the engine test and control system also comprises a single chip microcomputer (1), a test and control meter (4), a power analysis meter (2), a motor control device (3), an accelerator driving meter (5), a data acquisition meter (6), a signal processing system (7) and a tail gas analysis meter (8), wherein the test and control meter (4) and the power analysis meter (2) are connected with the single chip microcomputer (1); the motor control device (3) is connected with the power analysis meter (2); the accelerator driving meter (5) is connected with the test and control meter (4); the data acquisition meter (6) is connected with the tested engine; the signal processing system (7) is connected with the data acquisition meter (6); the tail gas analysis meter (8) is connected with the signal processing system (7); the control meter (4) is also connected with the tested engine. The engine test and control system can carry out detection by aiming at the discharge performance of the engine under different working conditions and improves the discharge performance of the engine when the engine leaves the factory. Meanwhile, the signal processing system has the advantages of high processing speed and high precision, and detection efficiency is improved.
Description
technical field [0001] The invention relates to a comprehensive performance testing system, in particular to an engine measurement and control system based on high-speed dynamic response of engine emission. 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. [0003] After the 1990s, the number of motor vehicles in my country has increased rapidly, and the pollutants emitted by motor vehicles have had a serious im...
