Abstract
The results of a study on the use of canola oil and canola oil with n-hexane in a compression-ignition engine are discussed. The engine with a common rail injection system was tested under actual road conditions and on a chassis dynamometer. The tested fuels were fed to the engine through an auxiliary fuel supply system. An analysis of the effect of the addition of n-hexane on the emission of the main toxic components of the exhaust gas was carried out. Feeding a diesel engine with unprocessed canola oil is difficult due to its physicochemical properties, which differ from diesel fuel. This is especially true for viscosity and density, at low ambient temperatures. The high viscosity of canola oil is significantly reduced by the addition of n-hexane. Observation of environmental parameters indicates that for pure canola oil (Co) and canola oil with the addition of n-hexane (10% and 15%), the level of NOx concentration relative to diesel (Df) was higher in both cases (measured before and after the catalyst). The observed quantitative change was mainly due to the operation of the exhaust after-treatment system. When the compression-ignition engine was fed with vegetable fuels, no significant differences were observed from diesel in terms of carbon dioxide (CO2) concentration. This leads to the conclusion that the use of canola oil with the addition of n-hexane may have an environmental effect due to the absorption of carbon dioxide during plant growth. The proposed solution can contribute to prolonging the service life of current compression-ignition engines by improving the ecological properties of this type of propulsion source. The only problem from the point of view of ecological conditions is the increased concentration of nitrogen oxides – further scientific considerations will be devoted to changes in the characteristics controlling the injection system so as to reduce NOx emissions.
