Biodiesel as a clean energy source could reduce environmental pollution compared to fossil fuel, so it is becoming increasingly important. In this study, we investigated the effects of different pilot injection timings from before top dead center (BTDC) and exhaust gas recirculation (EGR) on combustion, engine performance, and exhaust emission characteristics in a common rail diesel engine fuel...

– The rapidly depleting conventional petroleum resources have promoted research for alternative fuels for internal combustion engines. Among various possible options, fuels derived from triglycerides (vegetable oils/animal fats) present promising ‘‘greener’’ substitutes for fossil fuels. Vegetable oils, due to their agricultural origin, are able to reduce net CO2 emissions to the atmosphere alo...

A small group of heavy vehicle drivers underwent an ecodrive training course. Their driving was assessed for various ecodrive variables as they completed an 18 mile circuit in normal traffic immediately after the course and again 6 and 12 weeks later. Compared to pre-course measures, these drivers reduced their fuel consumption by an average of 27%, the number of gear changes by 29%, and the nu...

The fuel combustion in diesel engines can be improved by adding nanomaterials to the which result an reduction pollutant emissions and enhance quality of combustion. engine performance soot nanoparticles characteristics were evaluated this study with copper oxide (CuO2) rapeseed methyl ester (RME) under variable speeds. addition CuO2 RME significantly improve brake thermal efficiency (BTE) decl...

Alternative fuels have received much attention due to the depletion of world petroleum reserves and increased environmental concerns. Thus processed form of vegetable oil (Biodiesel) offers attractive alternative fuels to compression ignition engines. The present work investigates the engine performance parameters and emissions characteristics for direct injection diesel engine using coconut bi...

In this study a pseudo comprehensive carbon footprint model for fossil fuel power plants is presented. Parameters which their effects are considered in this study include: plant type, fuel type, fuel transmission type, internal consumption of the plant, degradation, site ambient condition, transmission and distribution losses. Investigating internal consumption, degradation and site ambient con...

In this study, performance and combustion characteristics of dual fuel operations (biogas, biogas+hydrogen) were experimentally analyzed compared with corresponding baseline diesel in four-cylinder, common-rail engine without thermal barrier coated piston. Tests conducted at three different loads (50 Nm, 75 100 Nm) a constant speed 1750 min-1. Engine pistons Yttria Stabilized Zirconia material ...

This paper describes the literature review of effect of different nano additives on performance and emission characteristics of diesel engine fuelled with different blends of biodiesel. This study is based on the previous research published articles. It was reviewed that by using nano additives with blend of biodiesel the performance characteristics were improved significantly but the exhaust e...

Currently, the main crop for biodiesel in Malaysia is palm oil. Recently, Jatropha curcas has drawn the attention of the Malaysian Government. This paper aims to study the feasibility of Jatropha as a potential biodiesel feedstock for Malaysia. Physico-chemical properties of Jatropha biodiesel and its blends with diesel followed by engine performance and emissions characteristics of B10, B20 an...

Herein, we investigated and analysed the performance characteristics of a compression ignition engine on methanol/diesel blends impact loads tailpipe emissions performance. Four combinations blended methanol were tested compared with pure diesel. Engine characteristics, such as: brake thermal efficiency, specific fuel consumption power analysed. HCs CO followed similar trends. The highest conce...
