Comparative assessment of different diesel engines fueled with 1‐pentanol and diesel blends

Abstract

1-pentanol has been gathering attention because of its advantages over the lower alcohols, and the researchers consider that it is a promising alternative fuel for diesel engines. In this study, two types of diesel engines were fueled with various blends of 1-pentanol (5%-35%) and diesel blends. Engine tests were performed using Onan DJC and Subaru RGD (3300H) unmodified diesel engines under different engine loads and speeds and results were reported and compared for both diesel engines.Test results of Onan and Subaru engines showed that average brake thermal efficiency (BTE) decreased, while brake specific fuel consumption (BSFC), and exhaust gas temperature (EGT) increased with increasing presence of 1-pentanol in the binary blends. Addition of 1-pentanol to diesel fuel significantly decreased oxides of nitrogen (NO x ) emissions, while hydrocarbon (HC) and carbon monoxide (CO) emissions increased drastically with the use of 1-pentanol as compared to diesel fuel. It is noted that the engine specifications, operating conditions and 1-pentanol blend ratio significantly affect HC emissions. As a result, the lowest ratio of 1-pentanol is the most promising candidate for decreasing NO x emissions, but at the expense of increasing BSFC for any type of diesel engine without any engine modification.

“…Due to the fact that the physical parameter predictable "Z" is based on independent variables (Z 1 , Z 2 , Z 3 , Z 4 , … P n ), errors with a magnitude of "P" would be assessed by Equation (2), which is dependent on error independent variables, belongs to the accuracy of instruments, and Y 1 is the measured output. Then the overall uncertainties would be estimated by percentage uncertainties, as shown in the example.…”

“…In response to the high demand for energy, governments are rushing to create a solid alternative renewable energy source, accelerated by rising emissions and the depletion of fossil fuel reserves. 1,2 It is necessary to use complete diesel fuel replacements such as ethanol and methanol and other engine modifications that are very expensive. 3 Partially replacing fossil fuels with biofuels, on the other hand, always helps to reduce emissions while also being costeffective.…”

Determination of the Optimum Blend Ratio of Diesel, Waste Oil Derived Biodiesel and 1-Pentanol Using the Response Surface Method

“…Although 1-pentanol has many advantages over other alcohols, a definite mixing ratio cannot be recommended in the current literature for its use as a co-solvent in diesel-biodiesel mixtures and for emission reduction purposes. Determination of optimum concentrations in a three-component mixture is a performance-requiring process both in terms of time and economy [24][25][26][27][28]. At this point, the response surface methodology, which is one of the statistical methods applied based on the experimental design, stands out as an effective method in determining the optimum concentration of the three components [28][29][30][31][32].…”
