Comparison of blends of conventional diesel fuel and CRBO containing high levels of FFA in a DI diesel engine
This work attempts to analyse the ability of high free fatty acid (FFA) crude rice bran oil (CRBO) in replacing diesel partially in a compression ignition (CI) engine. It was observed that the delay period and the maximum rate of pressure rise for CRBO blends are lower than diesel and is almost inversely proportional to FFA content. Maximum heat release rate for CRBO blends are lower and occur ...

Asia-Pacific Analysis: Go green not nuclear
Crispin Maslog says the region should follow the Philippines' lead and focus on renewable, not nuclear power. A year after the Fukushima nuclear disaster, questions remain over the role of nuclear power in the developing world, including South-East Asia and the Pacific. Nuclear power had a renaissance, driven by rapidly growing energy demands, and fading memories of high-profile disasters at ...

Gaseous release in LiNH2–MgH2 systems
Hydrogen is considered a safe and clean alternative to fossil fuels. Hydrogen storage is currently obtained by compressing the gas at high pressure. Researchers are currently attempting to tackle safety and energy density issues by locking hydrogen into solids, packing large quantities into small volumes. However, most of the known solids (i.e. intermetallics) show very low gravimetric density, ...

Effects of injection timing on the performance and emissions of a diesel engine fuelled with diethyl ether blended thevetia peruviana biodiesel
Fast depletion of petroleum reserves and existing emission norms drive us to search for the apt fuel for the IC engines. Biodiesel derived from vegetable oils is being tried now–a–days in most of the researches. A number of researches are in progress to reduce the emissions by using various techniques. In this study, the injection timing of a single cylinder diesel engine is advanced from 23° to ...

The performance and emission characteristics of a diesel engine using preheated Kusum oil and Kusum diesel blend
Rapidly depleting conventional petroleum resources have prompted research for alternative fuels. Among various possible options for internal combustion engines, fuels derived from triglycerides (vegetable oils/animal fats) are a promising substitute for diesel fuel. Vegetable oils pose some detrimental characteristics like high viscosity and low volatility compared to diesel fuel. In the present ...

Performance and energy analyses of a diesel engine fuelled with Koroch seed oil methyl ester and its diesel fuel blends
Performance of a single cylinder four–stroke diesel engine is analysed in the light of first law of thermodynamics in this study considering 10% (B10) to 40% (B40) (by volume) blending of Koroch seed oil methyl ester (KSOME) with diesel as fuels. An energy balance study is carried out to quantify the various losses associated with diesel engine processes on the basis of experimental data. ...

Externalities in North–South technology transfer: the case of CNG engines in Iran
This contribution focuses on illuminating the challenges and difficulties of North–South technology transfer. The central message of this paper is that North–South technology transfer is not simply a contract between two transacting firms and does not depend only on intra–firm and inter–firm factors. The process may also be influenced by a number of external factors, beyond the control or power ...

Full probabilistic service life prediction and life cycle assessment of concrete with fly ash and blast-furnace slag in a submerged marine environment: a parameter study
Nowadays, more attention is being paid to sustainability in construction. Over the years, the concrete research community has developed a wide range of potential 'green' concretes. To reduce cement related CO2 emissions, a considerable part of the traditional binder can be replaced with industrial by-products. However, as a result of the current focus on comparative durability assessment based on ...

Alternative fuels and managing a diverse fuel portfolio
Alternative fuels are becoming more prevalent in the marketplace at large and particularly within the waste industry. For example, Waste Management recently added its lOOOth natural gas fueled truck to its fleet this past summer. The alternative fuels that are going to work best for your fleet will take some investigation and research, but the prevailing data indicates that these solutions will ...

Incinerator location conflict: How opponents try not to be the losers of the public decision making?
The lack of monetary compensation and the difficulty for residents to exit close to an incinerator lead them to protest the construction of waste facilities. Opponents try to change undesirable locations to maintain their welfare. With a cost-benefit analysis, our incinerator location model attempts to measure both transportation and externality costs in comparable units. Two extreme behaviours ...

Parametric study of biodiesel quality and yield using a bench-top processor
Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...
