Measurement of Biodiesel Speed of Sound and Its Impact on Injection Timing: Final Report; Report 4 in a Series of 6

Research output: NRELSubcontract Report

Abstract

This study measures the isentropic bulk modulus, and speed of sound of biodiesel and the pure esters that are the constituents of biodiesel at temperatures from 20?C to 100?C and at pressures from atmospheric to 34.5 Mpa.
