Dosing Control of Urea in Selective Catalytic Reduction (SCR) to enhance the reduction of Nitrogen oxides
Abstract: Selective Catalytic Reduction (SCR) is an effective aftertreatment technique designed to comply with rigorous emission criteria established by global regulatory authorities for the elimination of nitrogen oxides from exhaust streams. Since NOx and ammonia reagents are poisonous and an excess of either is therefore very undesired, it poses an intriguing control problem, particularly at high conversion. SCR systems must reduce NOx emissions as much as possible and reduce the possibility …

Reduction of Pollutant for SI Engine Using Argon and Oxy-hydrogen
Abstract: Reducing the emission associated with oil combustion is gaining increasing interest worldwide. Due to their dangerous effects on human health, vegetation and climate, various pre-combustion, in-cylinder and post combustion techniques have been tried for their abatement. The combustion of a hydrocarbon fuel with air produces mainly carbon dioxide(CO2) and Water(H2O). However, internal combustion engines are not perfectly efficient, so some of the fuel is not burned, which results in the …

Proposal of System for High Efficiency Energy Extraction from LNG and Study of Use of EGR and SCR System in Ships
Abstract: The paper focuses on the green shipping methodologies and environment friendly practices. Liquefied natural gas (LNG) is one of the most effective alternatives to traditional shipping fuels. Ports have LNG re-gasification systems, which generally use Open Rack Vaporizers (ORVs) to convert the LNG to NG. In this process, a lot of the ‘cold energy’ is lost. A proposal for a LNG re-gasification system has been made in this paper which …

Evaluating the Effect of the EGR Rate on the Performance and the Emission of VCR Engine Operating on Jatropha Biodiesel Blends
Abstract: AbstractThe modern diesel engines running on biodiesel employ many techniques to encounter strict exhaust emission norms. Among the many techniques suggested to mitigate the NOX emission from the compression ignition engine, the Exhaust Gas Recirculation (EGR) system is being employed extensively. The EGR curtails the proportion of the oxygen in the mixture and lowers the flame temperature inside the cylinder. This research is intended to investigate the influence of the …

A Vehicle Emission Tax Model: To Promote Adoption of Zero Emission Vehicles for Indian Context
Abstract: Vehicle tailpipe emissions have been regulated by the authorities over the period of time forcing vehicle manufacturers in improving engine technologies to comply with the government stipulated norms. Improvement in engine designs has reduced vehicle tailpipe emissions to the extent of emissions to meet the notified norms. Historically, such a reduction in vehicle emissions has been achieved in steps/stages as and when new emission norms were notified. It is proposed …
