Abstract

The present study has the purpose of determining the levels of opacity with the use of diesel and biodiesel based on castor oil at 15\% (B15). For the determination of the opacity an electronic diesel engine test bench was used, the opacity measurements were made using a duly calibrated opacimeter. The Opacimeter consists of a probe which is installed at the end of the exhaust pipe, capturing the gases and yielding their own values for each test, considering the types of fossil fuel or biofuel and engine speed, subjecting several RPMs that go from 1200 to 3000 for each fuel. At the end of the tests, the opacimeter allowed to obtain an opacity of 11.1\% with fossil diesel and 0.386 with B15, obtaining a 96\% reduction in opacity. At the same time, an average opacity of the tests was obtained for each type of fuel, this value being compared with the national standards concerning this study. With these results, it contributes to the conservation of the environment since it emits less amount of soot, in the same way, the respiratory and heart diseases of people are reduced according to the world health organization.
