Abstract

Air pollution has become a growing problem in megacities and large urban areas throughout the globe, and transportation is recognized as the major source of air pollution in many cities, especially in developing countries. Contribution of automobiles is reported in the range of 40 to 80% of the total air pollution. The challenge facing megacities is how to reduce the adverse environmental impacts and other negative effects of transportation without giving up the benefits of mobility. This research paper includes the testing of bio-signal ring developed by Wellan International Limited for reduction of pollution levels in petrol and diesel vehicles and generator sets. The ring when attached to the inlet of the fuel pipe acts on the fuel through bio-signals. The bio-signals help in atomization of the fuel and reduce the pollutants by further enhancing the combustion process, and thus reducing the un-burnt pollutant particles from the exhaust. The ring was tested on diesel engines, petrol engines and generator sets. For diesel engine and generator set, reduction in smoke was measured, while in the petrol engine parameters such as CO, CO2, SOx and NOx were measured before and after attaching the ring. The percentage reduction of the pollutants obtained from the ring for the diesel engine is about 16.4%, and in petrol engine, significant reduction in the pollutants is observed. The average reduction in the opacity of the diesel generator set exhaust was 54.7%. Therefore, it is evident that the device can effectively control the issue of rising air pollution levels in residential, commercial as well as industrial zones.

Highlights

A bio-signal is any signal in living beings that can be continually measured and monitored
According to the tests performed on the diesel and petrol engine, it can be observed that a significant decrease in the pollutants released by the engine can be achieved with the help of the ring
The overall reduction in diesel engines with the aid of the ring was found to be about 16.18%, which shows that if these rings are fitted in diesel engine it can give a remarkable outcome in alleviating pollution levels

Summary

Introduction

A bio-signal is any signal in living beings that can be continually measured and monitored. The term bio-signal is often used to refer to bioelectrical signals, but it may refer to both electrical and nonelectrical signals. Electrical bio-signals, or bioelectrical time signals, usually refer to the change in electric current produced by the sum of an electrical potential difference across a specialized tissue, organ or cell system like the nervous system. Among the bestknown bioelectrical signals are: Electroencephalogram (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. Electrocardiography (ECG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin. Mechanomyogram (MMG) is the mechanical signal observable from the surface of a muscle when the muscle is contracted. At the onset of muscle contraction, gross changes in the muscle shape cause a large peak in the MMG [1,2,3,4,5]
