“…Diesel-RK is intended for full-cycle thermodynamic simulation of IC Engines and is used for combustion, performance, and emission analysis. It has advanced RK model which can be used to predict the performance and emissions over the whole operating range [7] and also provides simulation capability for biofuels and their blends with diesel [8]. In this work Diesel-RK has been used since its agreement with actual experimental data is reported to be very good [7], and recalibration of the model is not necessary for different operating modes of the engine [9].…”

On account of the energy crisis and search for possible next generation alternative fuel, biodiesels have emerged as a popular choice for research in case of diesel engines. The characteristics of biodiesel are similar to diesel and thus they have been the subject of research for many years. Efforts are being made to increase the Brake Thermal efficiency and decrease the NOx emissions from diesel engines when running on biodiesels. For this, extensive experimentation is required which is cost ineffective and exhaustive. This work investigates the performance and emissions of a single cylinder diesel engine running on Soybean Biodiesel by varying the Injection Timing via the numerical approach using Diesel-RK software. Simulations were carried out for three different injection timings of 23°, 26°, and 29° bTDC for Soybean Methyl Ester (SME), at different load conditions in terms of brake power and constant speed of 1500 rpm and the results have been compared with those of baseline diesel fuel. The predicted results show better engine emission characteristics for the advancement of injection timing except NOx emissions while engine performance is better for retardation of timing except PM and Smoke emissions. The performance of diesel fuel is better than Soybean biodiesel, while SME exhibits low Smoke and PM emissions.

“…Diesel engines are usually used on large buses, trucks, heavy duty equipment, agricultural equipment, and industrial machines. However, diesel engines also produce gaseous pollutants such as carbon monoxide (CO), carbon dioxide (CO 2 ), sculpture oxides (SO x ), nitrogen oxides (NOx), unburned hydrocarbons (UHC), and particulate matter (PM) . Until now diesel fuel is usually derived from fossil fuel, therefore alternative fuels are needed to replace fossil‐based fuels, for both reducing the consumption of fossil fuels and pollutants in the exhaust gases.…”

This research article mainly focuses on the influence of split injection (split into three injections) technique that was used to improve the ethanol fuel combustion in high compression ignition (CI) mode, with and without zirconia surface coating. This experimental and simulation was used (95% ethanol +5% water) as a fuel in a four‐stroke single‐cylinder variable compression ratio (VCR) engine. The VCR engine was used with optimized compression ratio (28.8:1) and experimental conducted on various load conditions. Performance and exhaust emissions of nitrogen oxides (NOx), carbon monoxide (CO) and unburned hydrocarbon (UHC) emissions of diesel, ethanol fuel single and split injection mode with coating and without coating were compared. The brake thermal efficiency (BTE) of split injection with coating mode was better than single injection mode. The VCR engine operating with ethanol fuel split injection mode showed peak BTE of 29%, which is nearly operating range in the baseline diesel engine. Ethanol fuel was mixed with 3% castorene R40 (lubrication oil) oil by volume due to fully soluble in alcohol fuels. It is used both air and liquid cooled engines running on methanol and ethanol fuel. Ethanol fuel split injection simulation was reduction of NOx compared with single injection simulation mode of operation. In comparison of diesel mode operation with zirconia coating was 3.8% increased than without coating. Ethanol single injection with coating CO emissions various from 0.5 to 3.0 g/kW‐hr. Ethanol split injection with coating mode CO emission various from 0.29 to 2.4 g/kW‐hr. © 2015 Society of Chemical Industry and John Wiley & Sons, Ltd

In this work experimental and theoretical investigations were carried out on a single cylinder, direct injection diesel engine operating on different blends of a soybean methyl ester (SME) with diesel fuel. The effect of blending on the cylinder pressure, heat release rate, carbon monoxide (CO), unburned hydrocarbon (UHC), nitrogen oxides (NOx), and smoke opacity were measured. The results indicate that the use of biodiesel produces lower smoke opacity up to 48.23% with 14.65% higher brake specific fuel consumption (BSFC) compared to diesel fuel. The measured CO emissions of B20% SME and B100% SME were found to be 11.36% and 41.7% lower than that of diesel fuel respectively. All blends of SME were found to emit significantly lower UHC concentration compared to that of diesel over the entire load. NOx emissions are observed to be higher for all blends of SME. The experimental results are compared with the results of Diesel-rk software and a good agreement between them is noticed.
