National Symposium on Rotor Dynamics - IIT Madras

December 19,20,21

Most machines have one or more rotating parts. Rotating machine elements thus form the backbone of industrial infrastructure and therefore play a pivotal role in the growth and development of the country. Rotor Dynamics is the key in design and maintenance of all such rotating machinery. This area has made tremendous strides in recent years.

ObCom 2011 - VIT

September 9

This International Conference is a major event to be conducted following the grand success of series of ObCom conferences during 2003, 2004 and 2006, which were audited by a good number of participants from Academia and Industry across the World. The past ObCom conferences received good contributions from academia, industry and research organizations. Our sponsors included governmental and non-governmental agencies like DRDO, ISTE, DIT, CSIR etc.

Abstract:
In this study a conventional diesel engine assembly is modified to work in the dual fuel mode with LPG as primary fuel and diesel as the pilot fuel. In this work, tests were conducted on a TEXVEL four stroke single cylinder diesel engine running with LPG in dual fuel mode of operation with diesel. Work reported is an attempt to study the extent to which LPG can be carbureted through manifold induction in a diesel engine. The investigation has been conducted to obtain brake thermal efficiency, emissions and total fuel consumption at various diesel substitutions and outputs.
There is an increase in the brake thermal efficiency from 40.4% in the diesel mode to 43.8% in the dual fuel mode at full load due to a rise in the combustion rate. However poor ignition leads to a drop in the brake thermal efficiency and increase in hydrocarbon and CO levels at low loads particularly with high diesel substitutions. It is seen that the CO levels reduce in the dual fuel mode with increase in the diesel substitution up to an output of full load. It is also noticed that the unburnt HC emission reduces from 810 parts per million (PPM) to 710 PPM with the dual fuel mode at full load.

  1. Very clear post about the diesel fuel!
