In this study, methanol in ratios of 5-10-15% were incorporated into diesel fuel with the aim of reducing harmful exhaust gasses of Diesel engine, di-tertbutyl peroxide as cetane improver in a ratio of 1% was added into mixture fuels in order to reduce negative effects of methanol on engine performance parameters, and isobutanol of a ratio of 1% was used as additive for preventing phase separation of all mixtures. As results of experiments conducted on a single cylinder and direct injection Diesel engine, methanol caused the increase of NOx emission while reducing CO, HC, CO2, and smoke opacity emissions. It also reduced torque and power values, and increased brake specific fuel consumption values. Cetane improver increased torque and power values slightly compared to methanol-mixed fuels, and reduced brake specific fuel consumption values. It also affected exhaust emission values positively, excluding smoke opacity. Increase of injector injection pressure affected performances of methanol-mixed fuels positively. It also increased injection pressure and NOx emissions, while reducing other exhaust emissions.

This paper discusses the brake specific fuel consumption and brake thermal efficiency of a diesel engine using cottonseed biodiesel blended with diesel fuel. A series of experiments were conducted for the various blends under varying load conditions at a speed of 1500 rpm and 2500 rpm and the results were compared with the neat diesel. From the results, it is found that the brake specific fuel consumption of cottonseed biodiesel is slightly higher than that of diesel fuel at different engine loads and speeds, with this increase being higher the higher the percentage of the biodiesel in the blend. And the brake thermal efficiency of cottonseed biodiesel is nearly similar to that of diesel fuel at different engine loads and speeds. From the investigation, it is concluded that cottonseed biodiesl can be directly used in diesel engines without any modifications, at least in small blending ratios.

Abstract Indeed, the development of alternative fuels for use in internal combustion engines has become an essential requirement to meet the energy demand and to deal with the different problems related to fuel. The research in this domain leads to the identification of adverse fuel properties and for their solution standard limits are being defined. This paper outlines an investigation of performance and combustion characteristics of a 4-stroke diesel engine using different cymbopogon (lemongrass) - diesel fuel blends. 10% to 40% cymbopogon is mixed with diesel fuel and tested for performance characteristics like brake specific fuel consumption and brake thermal efficiency. To obtain emission characteristics smoke density in the terms of HSU has been measured. In result, it has observed that there is an increase of 5% in brake thermal efficiency and 16.33% decrease in brake specific fuel consumption. Regarding emission characteristics, a 12.9% decrease in smoke emission has been found.

In order to reduce the fuel consumption and hydrocarbon and CO emissions of liquefied natural gas-diesel dual-fuel engines under light loads, an optimization control scheme, in which the dual-fuel engine runs in original diesel mode under light loads, is used in this paper. The performance and exhaust emissions of the dual-fuel engine and the original diesel engine are compared and analyzed by bench tests of an electronic control common-rail diesel engine. Experimental results show that the brake-specific fuel consumption and hydrocarbon and CO emissions of the liquefied natural gas-diesel dual-fuel engine are not deteriorated under light loads. Compared with diesel, the brake power and torque of dual-fuel remain unchanged, the brake-specific fuel consumption decreases, and the smoke density and CO2 emissions of dual-fuel decrease, while the hydrocarbon and CO emissions increase, and there is no significant difference in NOx emissions.

This study analyzes the performance of the diesel engine in terms of power, torque, specific fuel consumption, and thermal efficiency using diesel and pyrolysis oil. The waste plastic oil (WPO) used in this research was produced through a pyrolysis process using raw materials from Low-density Polyethylene (LDPE) mixed with diesel fuel in volume ratios WPO10, WPO20, WPO30, WPO40, and WPO50. In addition, a performance test was carried out on the single-cylinder diesel engine test bench. The results showed that performing the diesel engine with the addition of WPO increased the average power and torque by 5% and 3%, thereby producing a higher heating value. Furthermore, the concentration of WPO also reduces the level of specific fuel consumption to be more efficient, with a decrease in thermal efficiency. In conclusion, plastic waste pyrolysis oil is a promising alternative fuel applicable to a diesel engine.

The simulation method was used to study the fuel supply and injection characteristics of diesel top clearance plunger pump. The results show that the top clearance plunger pump relative advance of fuel supply is larger than that of the traditional plunger, and it can achieve the purpose of injection advance when the oil pump operate at 600~1000rpm. Through optimizing the structure of top clearance plunger, the amount of the injection advance can become larger and the advanced range of speed is increased. After optimized, the BSFC (Brake Specific Fuel Consumption) is 4.3% lower than that before when the diesel engine matched the top clearance plunger, which shows its advantage especially in working at high-speed.

Preheated Schizochytrium sp. raw microalgae oil (MAO) was evaluated as a fuel in a single-cylinder four-stroke diesel engine to produce a comparative study of MAO and diesel oil (DO) critical parameters. In particular, brake power, brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), in-cylinder pressure (CP), exhaust gas temperature (EGT), both nitrogen oxides (NOx) and carbon monoxide (CO) emissions were investigated. Additionally, an engine durability test for longevity was undertaken over a 30-h period, using raw MAO as the fuel. The study demonstrated that the preheated MAO could be successfully used in a diesel engine smoothly. The use of MAO reduced the engine brake power by 26% and increased brake-specific fuel consumption by 20%. The most significant finding from this research study is that there was a significant reduction in NOx and CO emission by 42% and 60% when using raw MAO, respectively. Therefore, these findings demonstrate that algae oil is a highly credible fuel for use in diesel engines and offers a promising solution to diesel engine emissions.
