This document summarizes a study on controlling aldehyde emissions from a 4-stroke spark ignition engine using methanol-blended gasoline with an improved catalytic converter design. The engine was tested with a conventional combustion chamber and one with a copper coating. Different catalysts including sponge iron and manganese ore were tested in the catalytic converter. Results showed that the copper coated chamber and catalytic converter with air injection reduced aldehyde emissions more effectively than other configurations tested.
This document summarizes a study on exhaust emissions from a four-stroke spark ignition engine operating on gasohol (ethanol blended with gasoline) with two different engine configurations: a conventional engine and one with a copper-coated combustion chamber. The engine was tested with and without an improved design of catalytic converter that used inexpensive sponge iron as the catalyst. Exhaust emissions of carbon monoxide and unburnt hydrocarbons were measured at various engine loads. The copper-coated engine configuration and use of the catalytic converter both reduced exhaust pollutants compared to the conventional engine operating on pure gasoline without a catalytic converter. Further reductions were seen when air was injected into the catalytic converter.
This document summarizes a study on the influence of injector opening pressure on exhaust emissions in a direct injection diesel engine with three levels of insulation operated on diesel fuel. Experiments were conducted with a conventional engine and engines featuring ceramic coated cylinder heads, air gap insulated pistons and liners, and a combination of the two insulation techniques. Exhaust emissions of particulate matter and nitrogen oxides were measured at varying brake mean effective pressures and injector opening pressures. The insulated combustion chambers showed higher nitrogen oxide emissions than the conventional engine, while particulate emissions were comparable. Increasing the injector opening pressure reduced exhaust emissions for all engine configurations.

This document discusses theoretical investigations of injection pressure in a four-stroke diesel engine using alcohol as fuel. A computer program was developed to simulate the engine's performance with diesel and at different alcohol injection pressures ranging from 180 to 160 bar. The results showed that an injection pressure of 165 bar for alcohol produced higher brake thermal efficiency and indicated thermal efficiency that were closest to diesel fuel. It was concluded that alcohol can be used in diesel engines with an injection pressure of 165 bar as it allows an optimum amount of alcohol to be injected while compensating for alcohol's low viscosity.

Comparative study of performance of dual plug and single plug si engine at diffIAEME Publication
The document describes a study that compares the performance of a dual plug spark ignition engine to a single plug engine. The dual plug engine was developed by introducing a second spark plug opposite the first plug. Experiments were conducted at different loads and compression ratios. Results showed the dual plug engine had better thermal efficiency, lower HC and CO emissions, but slightly higher NOx emissions than the single plug engine. The effect of compression ratio on the dual plug engine was also investigated, finding an optimum ratio for best performance and emissions.
The aim of this study is to investigate a technique to enhance the air swirl to achieve
betterment in engine performance characteristics in a direct injection (DI) single cylinder diesel
engine. A good swirl promotes the fast combustion and improves the efficiency. The engine should
run at low speeds in order to have low mechanical losses and fast combustion, enabling good
combustion efficiency. Therefore to produce high turbulence prior to combustion within the cylinder,
swirl induced by the inlet manifold will be helpful. This paper aims at studying the effect of air swirl
generated by directing the air flow in intake manifold on engine performance. The turbulence is
achieved in the inlet manifold with different types of internal threads of constant pitch. In view this,
experimental investigation has been carried out to find the effect of swirl on the performance
characteristics of the engine, by inducing swirl in inlet manifolds with three different types of
internal threads viz. acme, buttress and knuckle threads of constant pitch. The results indicate that
inlet manifold with buttress threads is identified as optimum configuration based on performance
characteristics of engine. This is because inlet manifold with buttress threads achieved a higher swirl
coefficient and swirl ratio compared with inlet manifold having acme and knuckle threads

This document summarizes a study on the performance of a diesel engine with oxygen-enriched intake air at different compression ratios. The study used a single cylinder variable compression ratio diesel engine with an eddy current dynamometer. Tests were conducted at two compression ratios (16.5 and 17.5) and two oxygen intake levels (1 L/min and 2 L/min). Results showed that brake specific fuel consumption decreased with higher oxygen intake and compression ratio. Brake power and exhaust gas temperature increased with higher oxygen intake and compression ratio. Optimum performance was achieved between 70-80% load with a compression ratio of 16.5-17.5 when oxygen intake was increased.
The document presents research on the experimental analysis of performance of a spark ignition engine with variable compression ratios between 6-9. The results show that brake thermal efficiency and brake mean effective pressure were highest at a compression ratio of 9, while specific fuel consumption was lowest. Emissions of carbon monoxide and unburned hydrocarbons decreased as the compression ratio increased from 6 to 9. The maximum improvement in brake thermal efficiency was approximately 10% when increasing the ratio from 6 to 9.

This document summarizes the design and analysis of an exhaust manifold expansion joint for a WDP4D diesel locomotive. The existing expansion joint design cracks due to high thermal stresses from exhaust gas temperatures over 600°C. A finite element analysis is performed to investigate fatigue phenomena. The analysis identifies high stresses in gaps in the existing design that reduce heat convection. The design is modified by increasing the bellow width and curvature area to improve heat transfer and reduce stresses. Thermal analysis of the modified design shows von Mises stresses under 150MPa, lower than the material yield strength, indicating the design is safe and cracks will not occur.
This document summarizes an experimental study on reducing oxides of nitrogen (NOx) emissions in a single cylinder diesel engine converted to run in dual fuel mode with compressed natural gas (CNG).

Performance analysis of ic engine using air energizereSAT Journals
Abstract In normal circumstances, due to incomplete combustion, 30% of the fuel remains unburnt and is emitted in the form of black smoke, causing air pollution. Moreover, the carbon originating from incomplete fuel combustions, settles on the spark plug and on the engine piston, thus diminishing the compression capacity of the piston and increasing the friction factor. This rate of carbon deposition increases especially in city driving, as the engine works much of the time at part throttle. Excess carbon decreases the compression ratio of the engine which ultimately robs the engine of its power, due to acute knocking or detonation. The above problem can be reduced to some extent by making use of paramagnetic property of oxygen present in the incoming air i.e. by passing the air through external magnetic field.

EFFECT OF INJECTION PRESSURE ON EXHAUST EMISSIONS OF DIESEL ENGINE FUELLED WI...IAEME Publication
In the context of exhaustion of fossil fuels day by day due to heavy demand with the use of agriculture sector and transport sector, escalation of fuel prices in International Oil Market causing huge economic burden on developing countries like India and rise of pollution levels with fossil fuel, the conservation of fossil fuels has become pertinent. Gaseous fuels have many merits over liquid fuels, as the pollutants emitted by gaseous fuels are low due to clean combustion, high calorific value in comparison with liquid fuels. Vegetable oils are good substitutes for diesel, as they are renewable, comparable calorific value and cetane (measure of combustion quality) number when compared with neat diesel operation. However, the disadvantages associated with vegetable oils such as high viscosity and low volatility cause combustion problems in diesel engines. They can be rectified to some extent by converting them into biodiesel. They are many methods to induct gaseous fuels such as port injection, carburetion technique, injection of gaseous fuel at the near end of compression stroke etc. Investigations were carried out with Acetylene gas as primary fuel inducted by port injection and diesel was injected into the engine in conventional manner. Particulate matter (PM), oxides of nitrogen (NOx), carbon mono oxide (CO) levels and un-burnt hydro carbons (UBHC) are the exhaust emissions from a diesel engine. They cause health hazards, once they are inhaled in. They also cause environmental effects like Green-house effect and Global Warming. Hence control of these emissions is an immediate effect and an urgent step. The pollutants of PM, NOx, CO and UBHC were determined at full load operation of the engine with varied injection pressure and compared with diesel operation on conventional engine. The maximum induction of Acetylene gas was 35% of total mass of diesel as full load operation. Particulate emissions were determined by AVL Smoke meter, while other emissions were measured by Netel Chromatograph multi-gas analyzer at full load operation. These pollutants were drastically reduced with induction of Acetylene gas and further reduced with an increase of injection pressure.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.
EXPERIMENTAL STUDY OF MECHANICAL AND TRIBOLOGICAL RELATION OF NYLON/BaSO4 POL...IAEME Publication
An experiment conducted in this study found that BaSO4 changed Nylon 6's mechanical properties. By changing the weight ratios, BaSO4 was used to make Nylon 6. This Researcher looked into how hard Nylon-6/BaSO4 composites are and how well they wear. Experiments were done based on Taguchi design L9. Nylon-6/BaSO4 composites can be tested for their hardness number using a Rockwell hardness testing apparatus. On Nylon/BaSO4, the wear behavior was measured by a wear monitor, pinon-disc friction by varying reinforcement, sliding speed, and sliding distance, and the microstructure of the crack surfaces was observed by SEM.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
