EXPERIMENTAL EVALUATION OF THE COMBUSTION AND EMISSION CHARACTERISTICS OF WASTE NON-EDIBLE RESTAURANT OILS AND HIGH-SULFUR DIESEL

Aug 1, 2023

Journal Journal of Engineering Science and Technology

Recently, researchers in the field of diesel engines have focused more on finding a green and environmentally friendly that reduces greenhouse gas emissions. Due to using diesel fuel with high sulphur content, Iraq's environment suffers from severe pollution. Using leftover cooking oil to produce biofuel is considered by many researchers as an alternative to conventional diesel fuel. Besides its high viscosity, this biofuel has a low cetane number, which reduces combustion efficiency when used purely. However, when mixed with diesel in certain proportions, as in the current study, unlike diesel fuel, engine performance and emissions are affected in different ways by it. Baghdad restaurants' cooking oil waste was used to produce biodiesel in this study, using di-esterification. This study aims to develop fuels with good specifications, low cost, and reduced sulphur content. A Biodiesel blend from wasted restaurant oil was mixed with Iraqi diesel, which is high in sulphur content, by volume ratios of 20%, 35%, and 50% and tested using a constant engine speed and varying loads. Testing results revealed that adding biodiesel in 20%, 35%, and 50% to pure diesel caused the brake-specific fuel consumption to increase by 2.6%, 5.9%, and 7.35%, respectively. A slight increase in brake thermal efficiency with varying engine loads was observed. Moreover, emissions of CO, HC, NOx, PM, H2S, and SO2 decreased by 18%, 23.4%, 3.5%, 46.4%, 47.5%, and 27.2%, respectively, when operating with a 50/50% biodiesel/diesel fuel mixture, compared to pure diesel.

This study examined the possibility of finding an alternative fuel to replace the Iraqi-origin gasoline. Iraqi gasoline has high levels of lead and sulfur compounds, so the pollutants emitted from it are very dangerous to human health and the environment. In the current study, butanol was added to gasoline with volume fractions of 25%–75% gasoline (G75B25) and 50% butanol to 50% gasoline (G50B50). The influence of these two alcohol ratios of blending on the performance and exhaust emissions of engine were compared. This study aims to provide a clean and healthy fuel as an alternative to gasoline of Iraq with low combustion emission content. The results revealed that mixing gasoline with butanol led to better engine performance and lower exhaust emissions compared to the case of gasoline fuel alone. When comparing gasoline with G75B25 blend, it shows a relative decrease in the specific brake …

Investigation of Thermal Behaviour of (Steel Alloy (44K2), Titanium Aluminide, SiO2, Al2O3, ZrO2) Materials on Internal Combustion Engine Valves

Volume 11

The paper aims to study the thermal stresses on an exhaust valve body with and without using the Thermal Barrier Coating technique (TBC) in the valve face region. A 2-dimensional model is created for the numerical analysis. The work is carried out with the aid of the ANSYS-APDL package. The procedure of the numerical analysis is divided into two processes. The first process is the thermal analysis to obtain the temperature values, which are set up as thermal loads for the structural analysis in the second process. The coating of the valve is carried out through three steps of analysis by selecting a single layer of TBC, a double layer of TBC, and a triple layer of TBC. Three types of TBC materials are taken in this work, which are SiO2, Al2O3, and ZrO2. The location of TBC type for the double and triple cases is taken into consideration, in the steps of analysis of double and triple design of exhaust vale coating is done by changing of the material type of TBC which it is on the upper or lower concerning the valve face. The results showed that using the SiO2 material as a TBC in the case of single, double, and triple coating of the exhaust valve face gives a low value of thermal deformations and thermal stresses. The stresses in steel alloy in cases without and with TBCs as compared to titanium valve showed a good reduction in thermal stresses for the titanium aluminide exhaust valve.

In this paper, the effect of laser surface heat treatment on wear resistance and hardness of an aluminum alloy Al-6061 as a base material with different ratios of SiC particles as an additive was studied. The composite material was prepared from Al-6061 aluminum alloy and particles with a granular size of (10-70) μm with different weight ratios (15%, 12%, 9%, 6%, 3%), where the stirred plumbing technique was used to ensure An increase in the wettability of SiC particles in the base alloy fuse and the possibility of distributing it uniformly. The laser surface heat treatment of the composite material prepared using the Neodymium - YAG laser was performed with a power of 1J, a wavelength of 1.06 μm, a pulse time of 5 m sec, and a distance of 30 cm between the exit area of the laser from the system and the piece to be thermally treated. The results showed an improvement in the mechanical properties of the prepared …

The tire coupling is torsional soft flexible coupling which is a feature that most desirable for optimum torque transmission. Designing the tire coupling by using the standard parameters and applying the torque for testing purposes will find the main deformation in the couplings. So we will try to improve the design to maximize the bearing effect for the coupling body. We will use the Solidworks simulation in order to visualize the failure spots on the body. In our research for testing we will apply a maximum torque 64 Nm and use rubber and polyurethane and other parts of the tire coupling are (Alloy steel). As a result we will compare these two materials (Rubber and Polyurethane) to find the optimum design.

This paper introduces an analytical study on the thermal effects on the diesel engine piston and its compresion rings during the contact between the piston and its compression rings. A three dimensional finite element model is built for the piston and its compression rings using the ANSYS v. 8 Finite Element Analysis Code that serves all engineering problems. The thermal analysis is made using contact case between the piston and its compression rings. The work in this paper did not include a convergence study.
