Abstract
A previous MFHS presentation described the tracking of rapid fuel injections (as short as 1 ms) in a
diesel internal combustion engine laboratory rig using Coriolis mass flow metering and Prism Signal
Processing (PSP). This presentation provides an update on this work. Petrol/gasoline engines operate at lower pressures, but may be subject to higher levels of mechanical noise. Additional PSP filtering techniques are required to remove unwanted noise sources to reveal the fuel pulses. Where fuel pulses are significantly shorter than the resonant frequency of the Coriolis flowtube, flow measurements are subject to systematic distortions that require further investigation.
