Investigation of Diesel Particulate Filter Behaviour Using Alcohol as a Fuel for Diesel Engine

Pollution and emission are major problem worldwide now a day. So, reduction of emission from vehicle is major requirement of any automotive industry. Diesel engines are widely used for heavy-duty vehicle because it have high efficiency, reliability and low operating cost. In addition to many advantages of these engines they are also responsible for environmental pollution caused by exhaust emissions. Four main pollutant emissions from diesel engine are carbon monoxide (CO), hydrocarbon (HC), particulate matter (PM) and oxide of nitrogen (NOX). Focusing on PM, it is harmful to our health because it causes heart or lung disease, irregular heartbeat, asthma, irritation of the airways and it also effect the environment. Various after-treatment processes use in diesel engine for emission reduction are diesel oxidation catalyst (DOC), selective catalytic reduction(SCR), NOX absorber technique and diesel particulate filter (DPF) and As per researcher, out of all after-treatment processes of emission reduction the Diesel Particulate Filter is best suitable for vehicle exhaust PM reduction. Many researcher uses various non-petroleum fuel such as alcohols, ethers, vegetable oils, bio-diesel etc. alcohol has low viscosity resulting easily injection, easily mixed with air and reduce pollutant emission so it getting high demand as fuel for CI engine. But many few focused on the behaviour of the DPF with alcohol as a fuel in diesel engine, taking DPF as the most effective means for the reduction of PM. The aim of this investigation is to know what variation occur in the DPF performance when we are using alcohol fuel in place of diesel fuel.
