“…They can not only reduce the local dependence on fossil fuels but also improve the efficiency of energy conversion when biofuels are used at the place of their production. 37 Although the engine performance and emissions of biodiesel and its blends with diesel were examined in agricultural engines, [38][39][40] the effects of the more promising biodiesel/butanol blends were not yet investigated.…”

Although both biodiesel and n-butanol are excellent renewable biofuels, most of the existing research works merely use them as the additives for petroleum diesel. As the main fuel properties of biodiesel and n-butanol are complementary, the biodiesel/ n-butanol blends are promising to be a pure biomass-based substitute for diesel fuel. In this paper, the application of the biodiesel/ n-butanol blends on an agricultural diesel engine was comprehensively investigated, in terms of the combustion, performance, and emission characteristics. First, the biodiesel/ n-butanol blends with 10%, 20%, and 30% n-butanol by weight were prepared and noted as BBu10 (10 wt% n-butanol + 90 wt% biodiesel), BBu20 (20 wt% n-butanol + 80 wt% biodiesel), and BBu30 (30 wt% n-butanol + 70 wt% biodiesel). It was found that adding 30 wt% n-butanol to biodiesel can reduce the viscosity by 39.3% and increase the latent heat of vaporization by 57.3%. Then the engine test results showed that with the addition of n-butanol to biodiesel, the peak values of the cylinder pressure and temperature of the biodiesel/ n-butanol blends were slightly decreased, the peak values of the pressure rise rate and heat release rate of the blends were increased, the fuel ignition was delayed, and the combustion duration was shortened. BBu20 has the approximate ignition characteristics with diesel fuel. Both the brake thermal efficiency and the brake-specific fuel consumption of BBu30 were increased by the average percentages of 2.7% and 14.9%, while NO x, soot, and CO emissions of BBu30 were reduced by the average percentages of 17.6%, 34.1%, and 15.4%, compared to biodiesel. The above variations became more evident as the n-butanol proportion increased.

“…Both UPME and CME blends achieved peak pressure in the range of 55.2-56.5 bar and 55.8-56.6 bar, respectively. Overall, there were decrement trends in peak pressure with a higher percentage of biodiesel in the blends, which were likely due to a decrease in ignition delays of the biodiesel blends compared to diesel [58]. Hossain et al observed constantly lower peak pressures in used palm cooking oil biodiesel compared to diesel in a three-cylinder engine, while a study by How et al reported reduced cylinder pressures for most of the coconut biodiesel blends tested [34,59].…”

Biodiesels from coconut and palm cooking oil are viable alternatives to diesel fuel due to their environmental sustainability and similar physicochemical properties compared to diesel. In the present study, these fuels were tested separately in a diesel engine by blending with fossil diesel in proportions of 10%, 20%, 30% and 40% by volume. Experiments were conducted under a constant brake mean effective pressure (BMEP) of 400 kPa and at 2000 rpm. The results revealed similarities in engine performance, emissions, combustion and engine block vibration for used palm cooking oil methyl ester (UPME) fuel blends and coconut methyl ester (CME) fuel blends. Most blends resulted in slight improvements in brake specific energy consumption (BSEC) and brake thermal efficiency (BTE). A maximum reduction of 54%, 89% and 16.8% in pollutant emissions of brake specific hydrocarbons (BSHC), brake specific carbon monoxide (BSCO) and brake specific nitrogen oxides (BSNOx), respectively, was observed with UPME and CME in the blends. The cylinder pressure profiles when UPME-diesel and CME-diesel blends were used were comparable to a standard diesel pressure trace, however, some deviations in peak pressure were also noticed. It was also apparent from the results that engine vibration was influenced by the type of methyl ester used and its blend composition. Notably, the rate of pressure increase was maintained within an acceptable limit when the engine was fueled with both of the methyl ester blends.

“…Biodiesel also poses cold start problems, fuel pumping difficulty due to higher viscosity, clogging and has lower energy content. 18,19 These troubles can be overcome by blending biodiesel with fossil diesel. In this study, 23% of biodiesel is blended with 77% of fossil diesel (B23) by volume for achieving 20% of energy content from fossil diesel.…”

“…Hence, the attention has been focused on the cheap and the abundantly available used cooking oil as a feedstock for biodiesel production. 19 This feedstock can be collected from food processing industry, fast food industries, hotels, hostels, and restaurants. This will also aid in minimizing the waste oil disposal issues.…”

Energy recovery from waste biomasses has become the most important solution, in addition to find suitable alternative fuel rather than the usual mineral fuel. In this study used vegetable oil biodiesel has been used as an injected fuel and waste wood chips as an inducted fuel to generate producer gas in a modified double walled fixed bed downdraft gasifier, and to study the fuel's performance in an Internal Combustion Engine. The effect of compression ratio on the engine performance is critically examined with different load while the fuel injection pressure and fuel injection timing has been kept constant throughout the run. The result shows that the brake thermal efficiency gradually increases with increase in compression ratio with simultaneous decrease in brake specific energy consumption; also the remarkable emission reduction ensures the suitability of mixed fuel at higher possible compression ratio without any modifications in the engine. It is concluded that the ignition delay, noise pollution, and engine vibration limit the compression ratio to 18 as a maximum. V C 2014 AIP Publishing LLC.
