Particulate matters especially particles with less than 2.5 micrometers (PM2.5) are the main cause of severe air pollution problem in Thailand that lead to the mortality risk in cardiovascular disease. Exhaust gas emissions specifically carbon monoxide and black smoke from diesel engines are the essential sources in generating significant amounts of PM2.5. Improving diesel properties by mixing oxygenated additives is one of the alternatives in reducing this pollutant. The main objective of this research is to investigate the performance and emission of a high-speed diesel engine at 3,000 rpm and different loads operated with diesel mixed with 5 to 20% ethanol and 5% ethyl acetate. The results of engine test at 80% load using diesel mixed with 5% of ethanol and ethyl acetate showed a few decreases in fuel properties and engine performance compared with diesel. The release of black smoke was also decreased to 14%. Increasing the mixture of ethanol to more than 5% has led to the decrease in engine performance continuously. The diesel mixed with ethanol at 20% and ethyl acetate at 5% has reduced the carbon monoxide and black smoke to 0.012%vol and 31.53% respectively and accrued the carbon dioxide at 1.25%vol. This is because the diesel mixed with ethanol and ethyl acetate increased the oxygen level to perform complete combustion as compared with diesel. However, the temperature of these exhaust gases was raised to 55oC

B5, diesel mixed with 5% biodiesel, is currently being developed to replace diesel, but there was lower engine performance. To improve the B5 properties, the addition of oxygenated additive is a better method. This research aims to study the performance of a high-speed direct injection (HSDI) diesel-engine generator at speed 3,000 rpm and different loads by using B5 blended to n-butanol and ethanol as increased to 20%. Results show that the use of B5-butanol-ethanol blends decreased engine performance as increasing ethanol; however, the release of nitric oxide, carbon monoxide, and black smoke was remarkably reduced as compared with B5. However, the use of B5 blended to 5% n-butanol, and 5% ethanol increased the electrical power to 0.33%, while electrical efficiency was added to 1.13%, and SFC was similar to B5. Therefore, this ratio can be applied with the diesel engines in the future.

Abstract: There is growing interest to study the effect of blending various oxygenated additives with diesel or biodiesel fuel on engine performance and emission characteristics. This study aims to analyze the performance and exhaust emission of a four-stroke, four-cylinder diesel engine fueled with biodiesel-ethanol-diesel. Biodiesel was first produced from crude Jatropha oil, and then it was blended with ethanol and fossil diesel in different blend ratios (B10E10D80, B12.5E12.5D75, B15E15D70, B20E20D60 and B25E25D50). The engine performance and emission characteristics were studied at engine speeds ranging from 1200 to 2000 rpm. The results show that the brake specific fuel consumption increases while the brake power decreases as the percentage of biodiesel and ethanol increases in the blend. The exhaust emission analysis shows a reduction in CO2 emission and increase in NOx emission when the biodiesel -to- ethanol ratio increases in the blends, when compared with diesel as a reference fuel.

This paper, an abstract of the original, is intended to provide information concerning the present status of Diesel fuel research. The paper is divided into two parts, the first of which concerns the types of fuel in use, describing briefly their sources and properties. A short account is also given of the existing fuel situation and how this may influence future research. Part II deals with the effects of fuel characteristics on engine performance, wear, and fouling. The methods of overcoming any deleterious effects caused by the fuel are discussed, and particular reference is made to the beneficial effects of lubricating oil additives. It must be emphasized that most of the work described refers to the high-speed Diesel engine, owing to the unsuitability of large units for laboratory testing. However, this is beneficial since the high-speed Diesel is most sensitive to fuel characteristics, and it serves to disclose the majority of defects that can arise in a Diesel engine.

In the paper researches of influence of using catalyst and polar additives on engine performance and emission of exhaust were carried out. The tests were made on diesel engine DuraTorq-TDDi/TDCi 16v with a capacity of 1998cm3 produced by Ford company. Two additives were investigated: FMAX – catalytic additive to fuel and HDOS – polar additive to lubricating oil in different proportions. The results indicated that using tested additives has a positive effect on exhaust composition (lower concentrations of nitrogen oxides, soot and carbon monoxide) and also decreased fuel consumption.

This study investigates the impact of an acetone-butanol-ethanol (ABE) mixture on spray parameters, engine performance and emission levels of neat cottonseed biodiesel and neat diesel blends. The spray test was carried out using a high-speed camera, and the engine test was conducted on a variable compression diesel engine. Adding an ABE blend can increase the spray penetration of both neat biodiesel and diesel due to the low viscosity and surface tension, thereby enhancing the vaporization rate and combustion efficiency. A maximum in-cylinder pressure value was recorded for the ABE-diesel blend. The brake power (BP) of all ABE blends was slightly reduced due to the low heating values of ABE blends. Exhaust gas temperature (EGT), nitrogen oxides (NOx) and carbon monoxide (CO) emissions were also reduced with the addition of the ABE blend to neat diesel and biodiesel by 14–17%, 11–13% and 25–54%, respectively, compared to neat diesel. Unburnt hydrocarbon (UHC) emissions were reduced with the addition of ABE to diesel by 13%, while UHC emissions were increased with the addition of ABE to biodiesel blend by 25–34% compared to neat diesel. It can be concluded that the ABE mixture is a good additive blend to neat diesel rather than neat biodiesel for improving diesel properties by using green energy for compression ignition (CI) engines with no or minor modifications.

In this investigation, biodiesel was produced from Moringa oleifera oil through a transesterification process at operating conditions including a reaction temperature of 60 °C, catalyst concentration of 1% wt., reaction time of 2 h, stirring speed of 1000 rpm and methanol to oil ratio of 8.50:1. Biodiesel blends, B10 and B20, were tested in a compression ignition engine, and the performance and emission characteristics were analyzed and compared with high-speed diesel. The engine was operated at full load conditions with engine speeds varying from 1000 rpm to 2400 rpm. All the performance and exhaust pollutants results were collected and analyzed. It was found that MOB10 produced lower BP (7.44%), BSFC (7.51%), and CO2 (7.7%). The MOB10 also reduced smoke opacity (24%) and HC (10.27%). Compared to diesel, MOB10 also increased CO (2.5%) and NOx (9%) emissions.
