This study evaluates the effect of partial fuel substitution with HHO (hydroxy) gas on a Jatropha oil biodiesel.For the experimental analysis, a stationary single-cylinder diesel engine was used, in which different conditions of load and rotational speed were established.Additionally, a thermoelectric generator (TEG) was installed in the engine exhaust system to power a HHO gas generator.

The study tested two types of fuels, commercial diesel and a biodiesel blend (JB10).In the case of the JB10, the addition of a volumetric flow of 0.075, old taylor whiskey 1933 price 0.

15, and 0.30 LPM of HHO gas were studied.The results indicated that for a 28 W production in the TEG, a minimum volumetric flow of 0.

32 LPM is achieved.The implementation of the TEG in the system avoids the extraction of energy from the engine to power the HHO generator while increasing up to 1.5% energy efficiency.

The addition of HHO gas enables a maximum increase of 9.71%, 7.39%, and 10% in the power output, energy efficiency, and exergy efficiency, respectively, compared to commercial diesel.

Also, HHO gas addition minimized HC, CO2, CO emissions, and opacity by 15.81%, 9.23%, 14.

89%, and 20.56%, respectively, compared to JB10 biodiesel.In conclusion, it was demonstrated that partial fuel substitution with HHO in the Jatropha oil biodiesel compensates lolasalinas.com for the adverse effects caused by the lower calorific value of the biofuel while reducing greenhouse emissions.
