ARMAS, Octavio; MATA, Carmen  y  MARTINEZ-MARTINEZ, Simón. Effect of diesel injection parameters on instantaneous fuel delivery using a solenoid- operated injector with different fuels. Rev.fac.ing.univ. Antioquia [online]. 2012, n.64, pp.9-21. ISSN 0120-6230.

This work describes an experimental setup for obtaining pressure variation and rate of injection profiles per engine stroke. This study focuses on the following experimental parameters: flow meter's backpressure, injection pressure, and duration of the process. An IAV EVI-2-type flow meter is used to measure the rate of injection. The work has been carried out using a common rail system with a solenoid-operated injector. As result, time profiles of: current intensity throughout the injector (electric pulse), pressure variation in flow meter (Δp) and the rate of injection are presented. The study has been carried out with four different fuels: a diesel fuel without biodiesel, a diesel fuel with 5.83% of biodiesel, a biodiesel fuel derived from animal fats and a synthetic diesel fuel derived from a Fischer Tropsch process at low temperature. The experimental set up and the established procedures have proven to be adequate for studies with current diesel injection systems. The differences registered in rate of injection have been mainly caused by the differences in density of fuels studied.

Palabras clave : Diesel injection; common rail; rate of injection; solenoid-operated injector.
