Oxygenated diesel fuel blends have a prospective effectiveness to reduce a particulate matter (PM) emissions and powerfully to be an effective alternative instead of diesel fuel. This manuscript investigates the emission characteristics of four combinations of oxygenated diesel fuel blends in terms of ethanol, TGME, Glyme and Diglyme. Two blended fuels containing 5% and 15 % by volume for each oxygenated additives was prepared. Pure diesel fuel was used as a base fuel for all oxygenated diesel blends. The experiments were conducted using four cylinders, four stroke compression ignition Toyota Hilux Pickup of engine capacity (2494 cc) model 2006, inline DOHC 16 Valve. The experimental results showed that (i) the higher engine speed is produced lower PM emissions; (ii) the PM emitted by all the oxygenated diesel blends is significantly lower than of the corresponding pure diesel fuel; (iii) the increase of oxygenated percentage in the diesel blends, the PM emission decreases; (iv) A maximum and minimum of PM reduction was occurred when the engine fueled by 15 % by volume for ethanol and by 5 % by volume for TGME respectively.

Blended Fuels

The use of biomass based renewable fuel, n-butanol blends for compression ignition (CI) engine has attracted wide attention due to its superior properties such as better miscibility, higher energy content, and cetane number as compared to other alternatives fuel. In this present study the use of n-butanol 10% blends (Bu10) with diesel fuel has been tested using multi-cylinder, 4-stroke engine with common rail direct injection system to investigate the combustion and emissions of the blended fuels. Based on the tested engine at BMEP=3.5Bar. Based on the results Bu10 fuel indicates lower first and second peak pressure by 5.4% and 2.4% for engine speed 1000rpm and 4.4% and 2.1% for engine speed 2500rpm compared to diesel fuel respectively. Percentage reduction relative to diesel fuel at engine speeds 1000rpm and 2500rpm for Bu10: Exhaust temperature was 7.5% and 5.2% respectively; Nitrogen oxides (NOx) 73.4% and 11.3% respectively.

Compression Ignition Engines

Alcohols begin to show a real interest for their use as fuel at compression ignition engines due to require reducing the pollutants emissions, especially NOx emission. Among the primary alcohols, butyl alcohol (butanol) is considered to be of great perspective in its use as fuel in diesel engines due to its properties close to those of diesel fuel. It is miscible with the diesel fuel and the achieved blend is stable. In paper are presented some aspects regarding the diesel engine’s fuelling with butanol and diesel fuel blends using the experimental research and numerical modelling. The use of the butanol as a fuel for diesel engine has led to the reducing NOx emissions with about 25% and the Brake Specific Energetic Consumption (BSEC) with about 5% at the full load and the maximum torque engine speed.

The stability and emission characteristics of diesel-ethanol-coconut methyl ester (CME) blends were studied to determine the most suitable fuel blends to be applied in diesel engines. This is done in order to assess the potential of the blends as a substitute for commercially available diesel fuel used in diesel engine. The stability results of the blends using 100% and 99.5% ethanol purity showed that the fuel blends containing ethanol up to 10% and CME of 5% and greater exhibited high mutual solubility at any temperature range and were resistant to microbial growths after 3 months storage. Engine operations at low speed especially at idle-no load and using a bigger size engine lead to a minimum ignition delay and result in lower fuel consumption rate. The emission test results with the new- blended fuels showed a reduction in CO2 and increasing percentage by volume of CO2 compared to commercially available diesel. The blends could deliver an efficient combustion and could run efficiently since production of the CO2 gases is higher than that of CO. The blends of 80% diesel, 5% ethanol, 10% CME; and 80% diesel, 10% ethanol, 10% CME could reduce the smoke opacity compared to commercially available diesel.

Ci Engine

Biodiesel is proven to be the best substitute for petroleum-based conventional diesel fuel in existing engines with or without minor engine modifications. The performance characteristics of biodiesel as a fuel in CI engine are slightly lower than that of diesel fuel. The emission characteristics of biodiesel are better than diesel fuel except NOX emission. The thermo-physical properties of biodiesel are improved by suspending the nano metal particles in the biodiesel, which make them an observable choice for the use of nanoparticles-added fuels in CI engine. High surface area of nanoparticles that promotes higher operating pressure and heat transfer rates that further quicken the combustion process by providing better oxidation. Thus, it has been inferred that addition of nanoparticles as an additive to biodiesel fuel blends in diesel engines and its effects on performance, combustion, and emission characteristics are discussed in this chapter.
