Development and implementation of virtual instrumentation based on LabView applied to compression ignition engines operated with diesel-biodiesel blends

This work shows the implementation and development of a set of virtual instruments focused on recording the physical parameters of a compression ignition engine that operates with diesel-biodiesel, 95% diesel and 5% soybean biodiesel. The components of the engine are constituted by several individual virtual instruments (VI) with the objective of registering parameters such as temperature (VITM), revolutions per minute (VIMRPM), fuel consumption (VIMFC), emission of gases such as oxygen (VIMO) and rust nitric (VIMNO). As a result of the research, the software development, hardware of each of the VIs is presented using the virtual programming platform Labview 2015®, the calibration of the O(2) sensors, NO and the result of the operation of the engine at 850 rpm constant an ambient temperature of 25 ℃, a relative humidity of 40% and an operating temperature at the engine head of 65 ℃, obtain a fuel consumption of 0.0616 l/min and an average emission of O(2) 10% and for the NO 540 ppm. • Implementation of virtual instrument focused on evaluate the physical parameters of CI engine operate with diesel-biodiesel. • The engine runs at 850 RPM under controlled conditions of 25 ℃ and a 40% RH with B5 mixture. • Engine emissions are constant and stable at 10% Vol. O(2) and 540 ppm of NO.
