Performance And Emissions

Biodiesel is an alternative diesel fuel that can be produced from renewable feedstocks such as vegetable oils, waste frying oils, and animal fats. It is an oxygenated, non-toxic, sulphur-free, biodegradable, and renewable fuel. Many engine manufacturers have included this fuel in their warranties since it can be used in diesel engines without significant modification. However, the fuel properties such as cetane number, heat of combustion, specific gravity, and kinematic viscosity affect the combustion, engine performance and emission characteristics. In this study, the engine performance and emissions characteristics of two different petroleum diesel fuels (No. 1 and No. 2 diesel fuels) and biodiesel from soybean oil and its 20 per cent blends with No. 2 diesel fuel were compared. The results showed that the engine performance of the neat biodiesel and its blend was similar to that of No. 2 diesel fuel with nearly the same brake fuel conversion efficiency, and slightly higher fuel consumption. CO2 emission for the biodiesel was slightly higher than for the No. 2 diesel fuel. Compared with diesel fuels, biodiesel produced lower exhaust emissions, except NO x.

Biodiesel Fuels

Biodiesel is an alternative fuel for diesel engines which doesn?t contain pollutants and sulfur; on the contrary it contains oxygen. In addition, both physical and chemical properties of sunflower oil methyl ester (SME) are identical to diesel fuel. Conversely, diesel and biodiesel fuels are widely used with some additives to reduce viscosity, increase the amount of cetane, and improve combustion efficiency. This study uses diesel fuel, SME and its mixture with aviation fuel JetA-1 which are widely used in the aviation industry. . Fuel mixtures were used in 1-cylinder, 4-stroke diesel engine under full load and variable engine speeds. In this experiment, engine performance and emission level are investigated. As a conclusion, as the JetA-1 ratio increases in the mixture, lower nitrogen oxide (NOx) emission is measured. Also, specific fuel consumption is lowered.

Biodiesel is the alternate fuel which is derived from renewable sources either is vegetable oils or animal fats. Biodiesel is non-toxic, have higher biodegradability, free of sulphur, no aromatics and its oxygen content of about 10-11% which is usually not contained in diesel fuel. These characteristics thus predominantly influences to the emissions of carbon monoxide (CO) and hydrocarbons (HC) in the exhaust gas. Purpose of this study is to investigate the effects of fuel additive, oil palm blended fuel, engine speed and test load conditions on the exhaust emissions and engine performance. The engine speed was varied from 1500 to 3000 rpm, load test condition varied by dynapack chassis dynamometer in 0, 50 and 100% and blends of 5(B5), 10(B10) and 15vol%(B15) palm oil with the diesel fuel. Increased of blends ratio with same mixing booster quantity can improve the engine performance, combustion process and give less CO emission. However, this condition tends to produce high NOx production due to higher oxygenated fuel in biodiesel content.

Increased of blends ratio can improve the combustion process and give less HC and CO emission and almost nearly engine performance. However, this condition tends to produce high NOx production due to higher oxygenated fuel in biodiesel content.

A study on the application of oxygenated turpentine oil as a bio-additive in diesel fuel was conducted. The purpose of this research was to investigate the effect of oxygenated turpentine oil additive in diesel fuel on the performance and emission characteristics in diesel engines. Oxygenated turpentine oil is obtained from the oxidation process of turpentine oil. In this experimental study, the influences of oxygenated turpentine oil-diesel blended fuel OT0.2 (0.2% vol oxygenated turpentine oil and 99.8% vol diesel) were compared with pure diesel on engine performance, and emission characteristics were examined in a one-cylinder four-stroke CI engine. The test was performed at two engine loads (25% and 50%) and seven engine speeds (from 1200–2400 rpm with intervals of 200 rpm). The physiochemical characteristics of test fuels were acquired. The engine indicated power, indicated torque, fuel flow rate, and emissions (carbon dioxide, CO2; carbon monoxide, CO; and nitrogen oxide, NOX) were examined. The results revealed that the engine power shows slight increments of 0.7–1.1%, whereas the engine torque slightly decreased with oxygenated turpentine usage compared to pure diesel in most conditions. Furthermore, a reduction in NOX emission decreased by about 0.3–66% with the addition of oxygenated turpentine in diesel compared to diesel. However, usage of OT0.2 decreased fuel flow rate in most speeds at low load but gave a similar value to diesel at 50% load. CO emissions slightly increased with an average of 1.2% compared to diesel while CO2 emissions increased up to 37.5% than diesel. The high-water content, low cetane number, and low heating value of oxygenated turpentine oil were the reasons for the inverse effect found in the engine performances.

Hydroprocessing of liquid biomass is a promising technology for the production of “second generation” renewable fuels to be used in transportation. Its products, normal paraffins, can be further hydrotreated for isomerization in order to improve their cold flow properties. The final product, usually referred to as “paraffinic diesel,” is a high cetane number, clean burning biofuel which is rapidly gaining popularity among researchers and the industry. Nevertheless, the costly isomerization step can be omitted if normal paraffins are to be directly mixed with conventional diesel in low concentrations. In this work, nonisomerized paraffinic diesel produced through hydrotreating of used cooking oil (hydrotreated used cooking oil (HUCO)) has been used in 4 blends (up to 40% v/v) with conventional diesel fuel. The blends’ properties have been assessed comparatively to European EN 590 and EN 15940 standards (concerning conventional automotive diesel fuels and paraffinic diesel fuels from synthesis or hydrotreatment, resp.). Furthermore, the HUCO blends have been used in a standard stationary diesel engine-generator set. The blends have been considered as “drop-in replacements” for standard diesel fuel. As such, no engine modifications took place whatsoever. The engine performance and exhaust emissions of steady-state operation have been examined in comparison with engine operation with the baseline conventional diesel fuel.

Diesel fuels were blended from selected components to provide aromatics contents from 10 to 57 percent and viscosities from 2.21 to 6.95 cSt (mm2/s) at 100°F (38°C) in a 14 fuel set which included a commercial diesel fuel as a reference fuel. Tests of the fuels were conducted under full load at several speeds and in the Federal 13-mode and smoke-cycle procedures, using a 2-stroke naturally aspirated engine and a 4-stroke turbocharged engine. Fuel properties such as viscosity, aromaticity, cetane number, gravity, distillation points, and heat of combustion, some of which were partially correlated, were examined individually and in combinations as predictors of the engine performance data. The two test engines responded similarly to fuel variables, but with some differences in sensitivity. Power output (bhp) and fuel economy (bhp-h/lb) were correlated with the heats of combustion on volume and weight bases, respectively. Smoke increased with the amount of fuel boiling above 640°F (338°C) and was not apparently affected by fuel aromatic content. Emissions of nitrogen oxides and of nitrogen oxides plus hydrocarbons increased with increasing fuel aromatics by itself or with increasing fuel specific gravity and decreasing fuel 50 percent-distillation temperature. Hydrocarbon emissions decreased with increasing viscosity or cetane number. Carbon monoxide emissions increased with increasing 90 percent-distillation temperature and with decreases in cetane number.

Combustion Phase

The performance and emissions of a compression ignition engine fuelled with diesel/dimethoxymethane (DMM) blends were studied. The results showed that the engine's thermal efficiency increased and the diesel equivalent brake specific fuel consumption (b.s.f.c.) decreased as the oxygen mass fraction (or DMM mass fraction) of the diesel/DMM blends increased. This change in the diesel/DMM blends was caused by an increased fraction of the premixed combustion phase, an oxygen enrichment, and an improvement in the diffusive combustion phase. A remarkable reduction in the exhaust CO and smoke can be achieved when operating on the diesel/DMM blend. Flat NO x/smoke and thermal efficiency/smoke curves are presented when operating on the diesel/DMM fuel blends, and a simultaneous reduction in both NO x and smoke can be realized at large DMM addition. Thermal efficiency and NO x give the highest value at 2 per cent oxygen mass fraction (or 5 per cent DMM volume fraction) for the combustion of diesel/DMM blends.
