Railroads are very fuel-efficient in moving freight by land. The history of rail begins with steam power, moving to eventual dieselization. Some components, advantages and disadvantages of internal combustion engines (gasoline, diesel) and external combustion engines (steam) are explored. Interesting developments with steam turbines and even gas turbine propulsion are recounted in this paper. Improvements...
In this paper, a novel biodiesel named rapeseed oil monoester of ethylene glycol monomethyl ether has been developed, which has one more ester group than traditional biodiesel. It was synthesized and structurally identified through FT-IR, 1H NMR analyses. Engine test results show that when atested diesel engine is fueled with this biodiesel in place of 0#diesel fuel, engine-out smoke emissions can...
Biodiesel is renewable and environmental friendly alternative diesel fuel for diesel engine. It can be produced from food grade vegetable oils, inedible oil, animal fats and waste or used vegetable oils, by transesterification process. Transesterification is a chemical reaction in which vegetable oils and animal fats are reacted with alcohol in the presence of a catalyst. The products of reaction...
Determine engine performance of a naturally aspirated direct injection diesel engine fueled with diesel and pungam methyl ester blend (PME20). Comparison of performance was done for different values of compression ratio, injection pressure and injection timing to find best possible combination for operating engine with PME20. It is found that the combined compression ratio of 19:1, injection pressure...
Short-term performance tests using crude palm oil (CPO) as fuel for a diesel engine showed CPO to be a suitable substitute of diesel fuel. However, prolonged use of CPO as fuel caused the engine performance to deteriorate. After 500 hours of cumulative running with CPO, the maximum power was reduced by about 20% and the minimum brake specific fuel consumption (bsfc) increased by about 26%. Examination...
This paper presents the results of investigations carried out on a single cylinder, direct injection, water cooled diesel engine operating on diesel, straight vegetable oils (Thumba oil and Neem) and 20% biodiesel blend of Thumba oil. The experiment covered a range of loads. Results show that Thumba oil can be used as an alternative fuel with better performance and lower emissions compared to Neem...
A substantial opportunity exists to reduce carbon dioxide (CO2) emissions as well as dependence on foreign oil by developing strategies to cleanly and efficiently use biodiesel, a renewable, domestically available, alternative diesel fuel. However, biodiesel utilization presents several challenges, including decreased fuel energy density and increased emissions of smog-generating nitrogen oxides (NO...
The aims of this research are to find, in decentralized production, more economical and effective techniques based on sustainable energy to extract and transesterificate oil to fuel (the use of ethanol, catalysts, and so on), to find new more effective filtering techniques to clean oils and fats for diesel fuel that produces less pollutants, verified by engine experiments, to find optimal regulations...
