Performance and Emission Characteristics of CI Engine fuelled with Pungamia Methyl Ester and it’s Blend with Diesel

Abstract
Unbalanced supply and cost escalation of petroleum fuels is a menace for diminution of renewable source of energy. The look for of alternate fuel for compression ignition engine has supposed great significance. Use of renewable biomass based fuel appears to be viable alternate with the commercial liquid fuel, predominantly for farm use. Amongst various fossil fuels for diesel, vegetable oil is a promising one based on the comparable fuel properties to that of diesel. Basically, internal combustion engines are designed to operate under conventional fossil fuel. However, the use of alternative fuel in existing engine needs modification but biodiesel can be used without any engine modification. Investigations were carried out to analyse the fuel properties of the biodiesel – Pongamia methyl ester as blend with diesel fuel from 20 to 80% by volume by running a diesel engine. Engine tests were carried out to evaluate brake thermal efficiency, brake specific fuel consumption and CO, CO2, HC, NOx emissions and smoke intensity. The outcome of the study reveals that the reduction in exhaust emissions together with increase in brake thermal efficiency and reduction in brake specific fuel consumption make the biodiesel a suitable alternative fuel for diesel fuel and environmentally benevolent.

Performance Enhancement of Solar PV System using Incremental Conductance Technique

Abstract
Photovoltaic systems normally use a maximum power point tracking (MPPT) control to continuously deliver the highest possible power to the load when variations in the insolation and temperature occur. The perturb & observe (P&O) technique, is very popular and the most commonly used in practice because of its simplicity in algorithm and the ease of implementation. But this method fails to track the power under fast varying atmospheric conditions. The proposed paper is using incremental conductance (incCond) technique intending to solve the problem of the P&O technique and the main difference of the proposed paper to the existing MPPT technique is eliminating Complexity of the incCond technique the effect of simplifying the control circuit. The resultant system is capable of tracking MPPs accurately and rapidly without steady state oscillation and also its dynamic performance is satisfactory.

COMPARATIVE STUDY ON PERFORMANCE AND EMISSION IN FOUR STROKE DIESEL ENGINE USING DIFFERENT BLENDED FUEL

Abstract
In today’s relevance, the application of diesel engine holds an important role. Though the economic and environmental aspects do not support the use of diesel nowadays, it is impossible to accomplish the habitual livelihood without diesel engine. Therefore it is mandatory to devise the use of diesel in an economic and environmentally benevolent manner. In the present scenario, the combustion efficiency of compression ignition engine is very low. The improper combustion leads to poor efficiency and the emission of incomplete combustion by-products. Hence it was planned to increase the combustion efficiency and thereby to increase the performance and to reduce the exhaust emission. The combustion efficiency of diesel can be further improved by reducing the ignition delay period. The present work was aimed at to improve the performance and to reduce the emission by using different chemical compounds at a definite proportion by volume with diesel, also to compare the performance and emission of the engine while using different blended fuel. For experimentation, different blended fuels in which various chemical additives blended with diesel were used as fuel. The observations were analyzed and the results were compared with the performance and emission characteristics of the engine while using diesel without any additives as fuel. The performance characteristic curves revealed that the addition of additives enhances the combustion efficiency of diesel; the outcome of the emission test concluded that there was an appreciable reduction in emission of combustion by-products.

Mobility Based Geographic Routing With Multiple Sinks in Mobile Sensor Networks

Abstract
In the research center on geographic routing, and a promising routing idea in wireless sensor networks (WSNs) is shifting in the direction of duty-cycled WSNs in which sensors are sleep scheduled to decrease energy utilization.. However, except the connected-k neighborhood (CKN) sleep scheduling algorithm and the geographic routing oriented sleep scheduling (GSS) algorithm, nearly all research work about geographic routing in duty-cycled WSNs has focused on the geographic forwarding mechanism.Sleep scheduling is a broadly used approach for reduction the energy of sensor nodes and prolonging the life span of a wireless sensor network (WSN). In this paper, we concentrate on sleep scheduling for geographic routing in obligation cycled WSNs with portable sensors furthermore, propose geographic-distance-based connected-k neighborhood (GCKN) sleep scheduling algorithm. That is GCKNF for first Scheduling calculation with multiple sinks. The approach is evaluated through simulation. Simulation results have confirmed the effectiveness of our new approach.

Automatic Classification of ECG signal for Heart Disease Diagnosis based on Probabilistic Neural Network and Self Organising Maps

Abstract

Electrocardiogram is one of the traditional methods used as a diagnosis mechanism for cardiac diseases which records the electrical activities of the heart. The intention of this work is to classify the ECG signal into normal and abnormal (Arrhythmia) category in an automated manner. The proposed work demonstrates an automatic classification system using the morphological features extracted from the ECG signal, and classified using effective techniques such as the Probabilistic Neural Network (PNN) and Self Organising Map (SOM) Model. MIT-BIH (Massachusetts Institute of Technology – Boston’s Beth Israel Hospital) dataset of both normal and arrhythmia patients has been used to substantiate the algorithms. The experimental results demonstrate the efficacy of the proposed method. A comparison is made for the experimental results obtained using both PNN and SOM model and the performance is studied. The SOM model has given a better performance of 97\% than PNN model during testing and both the normal and Arrhythmia categories are classified accurately.

Experimental Study on Performance and Emission Characteristics of a Four Stroke Diesel Engine Using Blended Fuel

                                          Abstract

In today’s applications, the use of diesel engine holds a key role. Even though the environmental features do not satisfy the use of diesel nowadays, it is not possible to accomplish the habitual livelihood without diesel engine. Therefore it is mandatory to devise the use of diesel in an environmentally benign way. In the present scenario, the combustion efficiency of compression ignition engine is very low. The improper combustion of fuel inside the engine leads to poor performance and emission of incomplete combustion by-products. Hence it was planned to increase the combustion efficiency and thereby to increase the performance and reduce the exhaust emission. For the experimentation, blended fuels of various proportions were prepared by blending Diethyl ether as additive with diesel. The observations were analyzed and the results were compared with the performance and emission of the engine using diesel as fuel without any additives. The performance characteristic curves revealed that the addition of additives enhanced the combustion efficiency of diesel; the outcome of the emission test also revealed that there was an appreciable reduction in emission of combustion by-products.
