Experiments were conducted to determine exhaust emissions and combustion characteristics of a conventional diesel engine (CE) and high grade low heat rejection diesel engine (LHR) (with air gap insulated piston with superni (an alloy of nickel) crown, air gap insulated liner with superni insert and ceramic coated cylinder head)with different operating conditions [normal temperature and pre-heat...

Stringent emission legislation all over the world has led to the search for alternative fuels for I.C. Engines. In this context, experiments were carried out to evaluate the exhaust emissions and combustion characteristics with a conventional diesel engine (CE) and ceramic coated low heat rejection (LHR) diesel engine [with ceramic coated cylinder head] with different operating conditions [norm...

In diesel engines, it is difficult to reduce both smoke and NOx simultaneously. An experimental study was conducted to determine the performance and exhaust emission characteristics of a commercial single cylinder, natural aspirated, air cooled DI diesel engine. The system was modified to work on either dual fuel or diesel alone. The objective of this work is to investigate the possibility of d...

Ooty the Head Quarters of Nilgiris Districts has a large Number of commercial and non-commercial vehicles, due to increasing industrialization and Tourism related activities. In this thesis a study was conducted on vehicle pollution in Ooty town to asses pollution contribution from transport sector. Pollution due to auto exhaust has assumed menacing proportion in the developing countries like I...

Pollution due to auto exhaust has assumed menacing proportion in the developing countries like India, where its contribution is nearly 45% 75 % of the total air pollution in urban areas, Ooty the Head Quarters of Nilgiris Districts has a large Number of commercial and non-commercial vehicles, due to increasing industrialization and Tourism related activities. In this thesis a study was conducte...

In order to reduce the temperature in marine engine cabin, improve working environment of staff and meet economy emission requirements, cooling system was experimentally investigated present study. this regard, water air-cooling schemes were studied main indicators including torque, smoke-emission, exhaust analyzed. The obtained results indicate that highest torque can be from turbine case pipe...

We developed a rapid kinetic bioassay demonstrating the inhibition of glutathione peroxidase 1 (GPx-1) by organic electrophilic pollutants, such as acrolein, crotonaldehyde, and p-benzoquinone, that are frequently found as components of tobacco smoke, diesel exhaust, and other combustion sources. In a complementary approach, we applied a high-resolution proton-transfer reaction time-of-flight m...
