  • Study of available exhaust gas heat recovery technologies for HD diesel engine applications

    Diesel engines reject a considerable amount of energy to the ambience through the exhaust gas. Significant reduction of engine brake-specific fuel consumption (bsfc) could be attained by recovering a significant part of exhaust gas heat. Various techniques have been proposed in the past to recover exhaust energy: mechanical, electrical turbocompounding and Rankine Bottoming Cycles. In the present ...

  • Case study - Engine cell exhaust: Catalytic oxidizer

    Overview Endurance testing of outboard motors for boats has typically been done in lakes and sometimes on barges. This testing was time consuming, presented logistic problems and removed the testing from the R & D department and the factory. When a company in Oklahoma decided to build their own endurance test cell area, the Environmental Protection Agency required them to control the ...

  • Diesel Particulate Filters in the City of London - Case Study

    The catalysed wall flow soot filter was designed and installed in the fourth quarter of 2008 to treat the Particulate Matter (PM), Volatile Organic Compounds (VOCs) & Carbon Monoxide (CO) in the exhaust gases from the outlet of an MTU 12V000G23E emergency generator installed in the basement in the financial district London EC2R. AirProtekt Catalysed Wallflow Particulate Filter is a system ...

  • Combinations of Measures for Reduction of NOx & Nanoparticles of a Diesel Engine

    Reduction of NOx- and particle emissions of Diesel engines is worldwide an important challenge for the engineers. Some unregulated components, like NO2, NH3 and naoparticles NP came in the focus of attention in the last years.Application of EGR and / or SCR can lower NOx, using RME (Bxx) can increase NOx. What happens with NP, parameter which enters in some further steps of exhaust gas ...

  • Performance and emission characteristics of CI engine, fuelled with diesel and oxygenated fuel blends

    Vegetable oils are a potential alternative towards partial or total substitution of diesel fuels. In this study, we used ethanol as the solvent, and a bio fuel enhancer as additive to explore the possible use of higher percentages of biodiesel in an unmodified diesel engine. Biodiesel was produced from cashew nut shell liquid (CNSL) by pyrolysis process. A mixture containing 80% (by volume) of ...

  • Diagnosing the effects of pilot fuel quality on exergy terms in a biogas run dual fuel diesel engine

    This work presents the exergy balances of biogas dual fuel combustion modes using two different pilot fuels in a single-cylinder diesel engine. The main focus is on the use of biodiesel (BD) as a pilot in place of fossil diesel fuel. The results reveal that the important exergy loss recovery sources are the exhaust gas and cooling water exergy. By accessing these losses, there is an increase of ...

  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...
