Global air pollution is a serious threat caused by excessive use of fossil fuels for transportation. Despite the fact that diesel fuel is a big environmental pollutant as it contains different hydrocarbons, sulphur and crude oil residues, it is yet regarded as a highly critical fuel due to its wide applications. Nowadays, biodiesel as a renewable additive is blended with diesel fuel to achie...

Fuel consumption reduction is one of the main challenges in the automotive industry due to its economical and environmental impacts as well as legal regulations. While fuel consumption reduction is important for all vehicles, it has larger benefits for commercial ones due to their long operational times and much higher fuel consumption. Optimal control of multiple energy buffers within the vehi...

This study explores different hybridization ratios of two types of parallel hybrid electric vehicles, a torque assist parallel hybrid and a full parallel hybrid, with equal powerto-weight ratio. The powertrain consist of an internal combustion engine, an electric motor, and a NiMH battery. The different hybridization ratios are compared by their optimal fuel consumption for eight different driv...

Compression Ignition (CI) engines are widely used for transportation, agriculture, power generation and industrial applications. The conventional fuel for CI engine is petro diesel. Among the countries in the world, India is one of the largest consumers of petro diesel fuel. Indian economy is very much dependant on the consumption of petro diesel. Brake thermal efficiency, brake specific fuel c...

This is an O Abstract — As a promising solution to the reduction of fuel consumption and CO2 emissions in road transport sector, hybrid electric powertrains are confronted with complex control techniques for the evaluation of the minimal fuel consumption, particularly the excessively long computation time of the design-parameter optimization in the powertrain’s early design stage. In this work,...

Application of unit fuel consumption has been explored deeply based on the second law analysis of thermodynamics to meet the strategy demand of optimizing energy structure adjustment. Theory of unit consumption analysis has been used in this paper to explore the theoretical foundation of energy structure adjustment. It has been proved that value of fuel exergy varies when two fuel exergy assess...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

Off-farm work is a growing reality in the US agricultural sector as a whole. Another staple program in the US agriculture is the use of crop insurance. This paper assesses hitherto unaddressed issues of fuel consumption and hence pollution generated by farm households associated with off-farm work and crop insurance. We applied a quantile regression method on a unique national farm-level survey...
