Particulate Matter (PM) is one of the major harmful substances in diesel exhaust gas. Technologies like the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC) have been positioned at the exhaust to reduce the quantity of harmful substances released to the environment. This paper highlights the factors that affect combustion in diesel engines and the potential of the introductio...

this work studies the biosurfactants production which enables the diesel biodegradation byusing mixed microbial consortia from polluted sites. it was carried out by culturing three microbial consortia(named as xa, xb and xc) obtained from polluted soils, and enriched in diesel as sole carbon source.batchexperiments were done to study the effects of three variables (temperature,hydrocarbon conce...

Nano-additives blended water-diesel emulsion fuel is the alternative fuel for compression ignition (CI) engine that reduce the NOx emission and at the same time increase the brake thermal efficiency due to combined effect of nanoparticles and micro explosion phenomenon of water diesel emulsion. This review paper addresses emulsion, emulsion types, micro-explosion phenomenon of water-diesel emul...

During three separate studies involving characterization of diesel particulate matter carbon nanotubes (CNTs) were found among diesel exhaust particles sampled onto transmission electron microscopy (TEM) grids. During these studies, samples were collected from three different diesel engines at normal operating conditions with or without an iron catalyst (introduced as ferrocene) in the fuel. Th...

The objective of this work is tomake an experimental investigation onchemical feasibility of karanja seed oilby modified the fuel using karanja methyl ester(biodiesel)blends withmineral diesel. This experimentation evaluatethe performance and emission characteristicsof 4stroke, single cylinder, DI diesel enginetest rig. The karanja biodiesel blended withdiesel in various proportions like 10%,20...

Increasingly stringent international diesel particulate emissions standards have re-established interest in Diesel filters. Modern Diesel engine technology, with computerized engine management systems and advanced, common rail injection systems, needs to be fully exploited in order to allow the application of efficient and durable Diesel filter systems, usually supported by catalytic aids, as s...

Our model suggests that spot diesel should rise 25 cents a gallon over the next six months and 41 cents a gallon over the next 18 months. americans who drive cars are no doubt aware of the drastic rise and fall in gasoline prices over the past few years. What they may not have noticed is the unusual movement in the price of diesel, a fuel primarily used in trucks, buses, railroad engines, farm ...

Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...

The paper investigates the result on the existing diesel engine that can suitably modified to operate on the diesel fuel mode to conserve diesel and also reduce environmental pollution. The conventional fuels, petrol’s and diesel for internal combustion engines are exhausted at an alarming rate, due to increase of vehicle population and also these fuel causes environmental problems. Make these ...

The prevention of wax formation under high pressure on new diesel engine requires a good understanding of the behaviour of the paraffin molecules crystallization. In this work a diesel from a Petrogal refinery was investigated under pressure. In particular the melting curve was measured from atmospheric pressure to 100 MPa by an optical technique. The behaviour of the solid phase with the press...
