Investigation on nonedible vegetable oil as a compression ignition engine fuel in sustaining the energy and environment
In the present investigation, a high free fatty acid (FFA) crude rice bran oil (CRBO), a renewable nonedible vegetable oil was tested on a direct injection compression ignition engine to find its ability to replace diesel oil and reduce the pollutants emitted. Three CRBO samples of different FFAs were tested in blended form to analyze the effects of high FFA with respect to engine performance and emission characteristics. With CRBO blends unburned hydrocarbon emissions were decreased significantly at all loads as a result of enhanced thermal oxidation inside the combustion chamber. The nitrogen oxides (NOx) emissions were reduced at lower loads and particulate emission reduced at higher loads. A marginal increase in carbon monoxide (CO) emission was noticed at all loads relative to diesel. The brake thermal efficiency of the engine was reduced marginally with CRBO blends. The experimental results show that high FFA CRBO can be used to partially replace diesel oil for a more sustainable energy and environment.
