This study examines the effects of lignite fly ash as a filler on the tribological and mechanical performance of a Calotropis gigantea fiber–epoxy composite. The investigation results show that the Calotropis gigantea fiber/epoxy composite with 2 wt.% lignite fly ash nanofiller added had better tensile strength, interlaminar shear, impact strength, and flexural strength than the control sample by 29.83%, 58.17%, 69.16%, and 11.41%, respectively. The manufactured composite samples were subjected to tribological tests, such as the friction coefficient and specific wear rate under dry sliding conditions with various process variables, such as sliding speed (1–3 m/s), functional load (10, 20, and 30 N), and sliding distance (1000 m). The results show that adding 3 wt.% nanofiller lignite fly ash to the Calotropis gigantea fiber/epoxy composites greatly improves the specific wear rate and friction coefficient. Additionally, the performance of the Calotropis gigantea fiber/epoxy composite...

The enormous rise in plastic waste leads to severe environmental issues and complete removal is a quiet challenge. The entire world focuses on finding new alternate for traditional conventional fuel. The waste low-density polyethylene is chosen as feedstock for the preparation of fuel from thermo-catalytic pyrolysis, considering the silica–alumina catalyst at a reaction temperature of 500 °C. From our previous study, the lower blends of waste low-density polyethylene exhibit a similar performance to diesel. However, brake thermal efficiency and oxides of nitrogen are not encouraging. Further improving combustion behaviour, the present research is carried out at different injection timings. The investigation is carried on standard injection timing of 23°bTDC and three retarded injection timings, namely, 21°bTDC, 19°bTDC and 17°bTDC. Retarded injection timing exhibits higher performance and lower unburned hydrocarbon, oxides of nitrogen and carbon monoxide emissions. However, smoke em...

The increasing demand for energy consumption because of the growing population and environmental concerns has motivated the researchers to ponder about alternative fuel that could replace diesel fuel. A new fuel should be cheaply available, clean, efficient, and environmentally friendly. In this paper, the engine operated with neat punnai oil blends with diesel were investigated at various engine load conditions, keeping neat punnai oil and diesel as base fuels. The performance indicators such as Brake Specific Energy consumption (BSEC), Brake thermal efficiency (BTE) and Exhaust gas temperature (EGT); emission indicators such as Carbon monoxide (CO), Oxides of Nitrogen (NOx), smoke opacity; and combustion parameters like cylinder pressure and heat release rate were examined. The Brake thermal efficiency of diesel is 29.2% whereas, it was lower for neat punnai oil and its blends at peak load conditions.

Agriculture is the important aspect of country economy. Farmers employ laborers for various purposes of works to be carried out on their farm. One of the important works is to make a ridge and furrow in their agricultural fields. In general, farmers use tractors, plowing machines, and other manual methods for making ridges and furrows in the agricultural field which increases the cost of operation to produce ridges and furrows. Further, the manual method of producing ridges and furrows needs more labor and takes more number of days to complete the work. Work. It also needs a lot of physical work. [1] . Plowing machines are costly and use power. This machine is highly economical and efficient which would replace the existing manual method of removal of furrows. Further, the machine is operated by freely available solar energy. The new machine is capable of reducing the physical work and also speed up the removal of wastages along the furrow. This furrow formation machine is mainly de...

To reduce the importance of fossil fuels, the identification of biofuels plays a vital role. The plant oil chosen for this study is novel plant oil named Jojoba oil (the botanical name is Simmondsia Chinensis). To utilise this type of oil in higher proportion with diesel, engine modifications were carried. The engine modifications include optimising salient operating parameters with Thermal Barrier Coating (TBC). Taguchi and Gray relational methods were used for finding the optimised values of salient operating parameters like injection pressure, compression ratio, injection timing and intake air temperature as 275 bar, 19.5 CR, 27.5 bTDC and 65˚C, respectively [1]. This has helped to combust the higher blends of jojoba oil, namely 60J, 70J and 80J, without adverse performance and emission characteristics. The fundamental aim of coating Aluminium oxide, Molybdenum and Titanium oxide (40%, 30% and 30%) on the inner surface of the piston crown and the cylinder head is to retain heat a...

Abstract The material handling equipment assures the convenient conveyance of the required quantity of material at the desired restriction with the lowest cost and greater security. Due to the steady development of new technology over material handling machinery is witnessing continuous automation. The problem occurs when turning the soft material like cordierite ceramic material before the fire in the kilns. The soft surfaces experience fractures that are often difficult to see naked eye during spinning. A bat for kiln must bear the turned product. By using a clamping lot, the stock would be turned. The material of two ratchet belt carries a product using two clamps.

Abstract There is a necessity to find suitable substitutes for the petroleum-based fuels as conventional fuels are decreasing in order in recent decades. Vegetable oils are more attractive as an alternative fuel for diesel as they are renewable and can be used in engines without employing any significant modifications. The main problems with the use of vegetable oils in diesel engines are high smoke levels and relatively low thermal efficiency due to high viscosity and carbon residue as compared to diesel. The usage of biodiesel increased due to the shortage of availability and increase in the cost of standard fuel in the market. In this paper, the chrysopogon zizanioides dry seeds were converted into nano-sized particle as the additive and blended with biodiesel-diesel blends with various volumetric proportions were used as fuel. The performance parameters of a diesel engine fuelled with standard diesel and chrysopogon zizanioides nano particle mixed biodiesel blends were evaluated. Engine emission tests for diesel fuel with chrysopogon zizanioides nanoparticles were performed. From the experimental results, it was observed with the addition of nano particles decreases emissions of hydrocarbons and carbon monoxide, carbon dioxide, nitrogen oxide, smoke and increases oxygen and proved that the fuel prepared with nano additives could be a replacement for the standard diesel.

Abstract The methyl ester is a sustainable, biodegradable and non-toxic fuel. Vegetable oil can be converted to methyl ester through a process of transesterification. Very a few works have been published in the literature on the use of two different methyl esters in the blended form of diesel fuel. In the present work, however, two methyl esters, namely PME and MME, were chosen and used as fuel in the blended form. Palmitic and oleic acids are the main fatty acid composition of methyl esters. The existence of a single bond of oleic acid in methyl esters can improve the combustion characteristics. Empirical studies on diesel engine reveal that there is a reduction in brake thermal efficiency (BTE) and an increase in NOx emissions and CO2 emissions with an increase in the concentration of methyl ester in the blend. However, the emissions such as Smoke, CO and UHC were reduced significantly. At rated power, Brake thermal efficiency values of standard Diesel, and blends B20, B40, B60 and B80 are 29.1%, 28.5%, 28%, 27.4%, and 26.9% respectively. The NOx emissions are in the order of 1515 ppm, 1546 ppm, 1552 ppm, 1566 ppm and 1630 ppm and smoke emission are 4.4 BSU for diesel fuel whereas it decreased with the increase of methyl ester in the blends. The same trend has been observed for hydrocarbon emissions. The study reveals that the B20 blend (80% Diesel + 10% Pongamia Methyl Ester + 10% Mahua Methyl Ester) is similar to that of diesel fuel in terms of performance and oxides of nitrogen emission.

Abstract Diesel engines are commonly known for its high-power output and high performance. However, the rise in energy consumption, the gradual depletion of petroleum fuels and compliance with strict emission regulations are of great interest to researchers to produce alternative fuels from renewable energy resources. Of all the different alternative fuels, vegetable oil replaces traditional diesel fuels. The transesterification process is frequently used in the process of extracting biodiesel from vegetable oils. In this process, triglycerides are converted into monoglycerides using alcohol and a catalyst at a specific reaction temperature. In this experimental work, pongamia and mahua oil having a higher composition of Palmitic and oleic fatty acids are used to extract biodiesel through a transesterification using methanol and KOH catalyst. Since the combustion process in diesel engine is very complicated because of heterogeneous spray combustion. The physiochemical properties of biodiesel vary when compared to diesel fuel. It is essential to study the influence of Palmitic and oleic fatty acids on combustion parameters of diesel engines. Palmitic and oleic acids are the main fatty acids of pongamia and mahua biodiesel. This was the key inspiration for this research to understand and examine the combustion behaviour of CI engines fuelled with methyl ester containing a higher composition of Palmitic and oleic acid mixture. The experiment was performed with a diesel engine for diesel and pongamia and mahua biodiesel blends (PME25, PME50, PME75 and PME) as a fuel. The combustion parameters namely, in-cylinder pressure, the MRPR, HRR, cumulative HRR, ID and CD were evaluated. It was observed that the ID and the MRPR reduced for biodiesel than diesel due to higher cetane number of biodiesel blends showing a smoother operation of the engine. The longer combustion duration was detected for all methyl ester blends, resulting in poor engine performance for biodiesel blends.

In this paper, we carried out a study to upsurge the brilliance of the plungers used in the braking system. The main focus has been taken on various defects that occur in the plungers during manufacturing. In this work, we analyzed the types of defects that transpire in the plunger. The foremost issue is acknowledged using tools like Pareto graphic representation, root and effect diagram, Failure Mode and Effect Analysis, Trend Analysis and Control chart. We identified more frequently occurring defects and major causes and effects of these defects in plungers. Based on the result of the analysis, interpretation measures are taken to overcome the defects of the plungers that will help to improve the overall efficiency of the brake system in vehicles.

Abstract Developing an efficient and economic solar dryer for continuous drying of agricultural food products has become potentially a viable substitute for fossil fuel in developing countries like India. Drying is a process of removing moisture content from the most important agricultural products like fruits and vegetables. This process is widely used for preservation and storage of agricultural products. The fruits and vegetables must be maintained at good quality because it has very high nutrition. The best way to maintain its nutritional value is to keep the items as fresh. Multiple methods are available for this preservation, but drying is the most common way of preserving food because the storage life is increased. Solar power is used for drying fish and agricultural products such as cocoa, coffee, rubber, cotton, tobacco, corn, tea. There are various types of solar drying systems were available for agricultural food products. Therefore, in this review paper, an attempt has been made to summarize the previous and current research in the field of solar dryers for drying of agricultural food products. Solar tunnel drier architecture, solar drier testing with drying vegetables, economic analysis and dried crop quality analyzes were discussed. In some cases, the moisture content of these items reaches 90%. The quality of water is considered the main cause for the development of microorganisms contributing to decomposition. The efficiency of a solar dryer with both a natural and a forced convection solar drier for fruit and vegetables were analyzed and compared in this article. Drying rate, weight losses and humidity removal were discussed.

Abstract A tricycle is a three-wheeled human-powered vehicle. This vehicle is powered by humans so greater human effort is required for operating this vehicle. Tricycles are classified as a hand-driven tricycle, motorized tricycle, electric tricycle. The hand-driven tricycle makes the user tiring. The motorized tricycle uses internal combustion engine which may lead to pollute the environment. The main objective of this work is to produce an eco-friendly motorized tricycle. This electric tricycle uses a motor which is driven by energy stored in the battery. The energy can be obtained from non-conventional sources thereby causing no harm to the environment. In this work, photovoltaic cells were used to obtain the electricity needed to drive the motor. These photovoltaic cells convert solar energy into electric energy. Therefore, this eco-friendly method is used for producing electricity. The main aim of this work is to study a tricycle powered by energy obtained by solar cells for physically challenged people. This tricycle can be operated by physically challenged persons to travel to longer distances without much effort.

Biofuels, namely, biodiesel and ethanol produced from renewable energy sources are used as fuels in the blended form along with diesel to investigate the performance and emission characteristics of a DI diesel engine. Diestrol blend consists of diesel, biodiesel/methyl ester and ethanol. In diestrol blends, ethanol percentage is steadily elevated with an incremental factor of 5% culminating into three blends with a maximum percentage of 15% by volume and named as EB5, EB10 and EB15 respectively. A comprehensive analysis of engine performance characteristics such as brake thermal efficiency, brake specific fuel consumption, exhaust gas temperature and emission characteristics such as carbon monoxide, carbon dioxide, unburned hydrocarbon, oxides of nitrogen and smoke opacity were carried out. From the above investigation, it was found that brake thermal efficiency increased by 3%, 5% and oxides of nitrogen emission decreased by 23%, 24.5% when compared to diesel and B20 respectively.

For many decades all major conservation bodies have realized the need to conserve our valuable fuel and power sources. The increased level of consumption of fuel and power results in carbon-di-oxide emissions to environment which results in the depletion of ozone layer leading to global warming. As a result, many ways of utilizing renewable fuel and power sources are developing with solar energy and waste heat recovery applications. Most of the process and industries have large capacity Diesel Generating (DG) set. The exhaust gas of such a DG set carries a lot of heat and it goes waste if it is not utilized properly. Energy recovery from engine exhaust is one of the energy saving methods in engines. By using energy recovery techniques, waste heat energy can be saved, emissions can be reduced and thermal efficiency of the engine is increased. This paper discusses about the exhaust gas energy recovery from engine exhaust using Rankine cycle and thermodynamic properties of the working ...
