Abstract
Modern tendencies in the development of diesel engines include the operation
of the system for injecting diesel fuel at pressures higher than 100 MPa.
Knowing the characteristics of liquid fuels such as speed of sound, bulk
modulus and density depending on pressure, is important for predicting the
behavior of fuel injection systems for diesel engines and optimization of the
same. The paper presents an original method and apparatus (device) for
determining the speed of sound and density of fluids depending on the
pressures. With this method, values of these characteristics for rapeseed
oil, biodiesel and conventional diesel fuel at pressures up to 160 MPa are
determined. The method is non-destructive, it can also be applied to higher
pressures than 160 MPa, as well as other liquid fluids that are used at high
pressure - hydraulic oil, for example.
