Real Time Air Pollution Monitoring and Control System for Diesel Engine

Abstract

In recent years, the motor industry has been promoting the diesel car due to their greater fuel economy and reduced maintenance requirements. However, diesel cars have much harmful emission characteristics and an increase in diesel cars at the expense of petrol cars have caused negative impacts on urban air quality and caused global warming and other environmental issues. Apart from the various particulate matters, diesel engine mainly emits two pollutant gasses, carbon monoxide (CO) and nitrogen oxides (NOx). Among those two, the NOx is more harmful and is causing various negative environmental and harmful health related issues. Although, there are many systems proposed to encounter these issues but most of them either costly or difficult to implement and handle. Under such demand and availability scenario, present research has successfully designed and implemented a real-time low-cost NOx monitoring and removal system applicable for diesel engine. System designed under present research has successfully monitored and displayed NOx level in engine exhaust at various operating scenarios and also achieved 20% reduction in NOx level with its low-cost chemical filter. Although, technology proposed and developed under present research is at its early stage but with maturity, in near future it will successfully encounter diesel engine related harmful air pollution.
