Selective Catalytic Reduction systems (SCR) are very efficient on reducing NOx. However, they only perform properly when exhaust gas temperature is higher than 180 °C. This means that for low engine regimes combined with cold temperatures, SCR remains inactive. study presents a new approach to minimize the amount of NOx emitted by diesel engines Heavy-Duty Vehicles during and gases conditions. ...

The search for alternative fuels that can limit the use of traditional fossil to power internal combustion engines is one main tasks faced by both modern automotive industry and energy industry. This paper presents experimental tests a compression ignition engine, in which conventional fuel, i.e., diesel, was partially replaced with propyl alcohol, renewable biofuel. Studies on co-combustion di...

This paper presents an experimental investigation on a four-stroke single cylinder diesel engine fuelled with the blends of Mahua oil methyl ester (MOME) and diesel. The performance emission, energy, and exergy analysis has been carried out in B20 (mixture of 80% diesel by volume with 20% MOME). From energy analysis, it was observed that the fuel energy input as well as energy carried away by e...

The objective of this study was to test the performance of diesel engine using diesel B3 mixed with crude palm oil in ratios of 95 : 5, 90 : 10, and 85 : 15, respectively, and to compare the results with diesel B3. According to the tests, they showed that the physical properties of the mixed fuel in the ratio of 95 : 5 were closest to those of diesel B3. The performance of the diesel engine tha...

Vegetable oils are renewable in nature and can be directly used as fuels in diesel engines. However, their high viscosity and poor volatility lead to reduced thermal efficiency and increased hydrocarbon, carbon monoxide and smoke emissions. Transesterification is one of the methods by which viscosity could be drastically reduced and the fuel could be adopted for use in diesel engine. This Ester...

Standalone diesel systems have been widely used on Malaysian islands due to the isolated locations of the islands. Nevertheless, the high diesel prices and the high cost of transporting diesel to islands cause the use of standalone diesel systems to be uneconomical. This study analyzes the feasibility of implementing PV (photovoltaic) systems as alternatives to standalone diesel systems by cons...

This paper represents the prospect of mustard oil as a renewable and alternative fuel. To cope up with present load-shedding situation and to reduce the dependency on imported fuel, Bangladesh government is encouraging the use of renewable energy sources. Since diesel engines have versatile uses including small irrigation pumping systems, and standby small electricity generators, use of diesel ...

Petroleum based products are the major source of energy for industries and daily life. Leaks and accidental spills occur regularly during the exploration, production, refining, transport, and storage of petroleum and petroleum products. In the present study we isolated the bacteria from diesel contaminated soil and screened them for diesel biodegradation capacity. One monoculture isolate identi...
