Abstract: The paper presents the
development of transient speed measuring system of internal combustion engine
based on the C8051Fseries
microcontroller.The system may accomplish measurement of transient speed of
internal combustion engine and speed fluctuation under speed governing and
starting condition.The system runs with two measuring methods of the
high-frequency count and the frequency domain sampling.The test results
indicate that the system meets the demands of transient speed measurement of
internal combustion engine under various working conditions and has well
effects on transient speed measurement.
