The diesel engine is robust, has a long working life, and is fuel efficient. It has been used widely in ships, railway locomotives, and as a stationary engine to provide power, and there is increasing use worldwide in heavy duty and public transport vehicles and passenger cars. Dieselengined vehicles are widely used in underground mines and it is here that there is the highest human exposure.

Evaluation of the torsional vibration characteristics of a crankshaft system is indispensable to the development of marine diesel engines. It influences the selection or decision about shafting components such as the flywheel, torsional damper, generator and even modification of the crankshaft itself. In this paper, experimental and analytical investigations of torsional vibration were carried ...

Compound-specific isotope analysis (CSIA) offers great potential as a tool to provide chemical evidence in a forensic investigation. Many attempts to trace environmental oil spills were successful where isotopic values were particularly distinct. However, difficulties arise when a large data set is analyzed and the isotopic differences between samples are subtle. In the present study, discrimin...

which are in a nonconservative form. Global conservation is not guaranteed if integration is performed for Eqs. (2) and (3), which do not include PDF inside the temporal and spatial derivatives. On the other hand nonconservative forms allow a relatively coarse mesh since conditional averages show much less spatial dependence than PDF weighted Favre averages. Here η ρ ρ η ≡ and the scalar dissip...

Abstract: As day by day there is technological development seen all around world, the research work is progressing but the resources involved in them are depleting rapidly .The demand of resources and fuels for the technological development is increasing day by day. In order to keep the pace of development high there is a need to think about some alternate fuel with better efficiency which woul...

For the high-power low-speed diesel engine’s performance and reliability evaluation, this paper studies the engine’s running-in norms, presents the Test Scheme about the combustion process, the Inlet swirl control, the cooling system control, and the distribution and emission. The whole engine’s test methods and systems are established. By using the combined method of the test platform research...

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...

Numerical simulation of the vaporization of multi-component liquid fuels under high-pressure conditions is conducted in this study. A high-pressure drop vaporization model is developed by considering the high-pressure phase equilibrium which equates the fugacity of each component in both liquid and vapor phases. Peng-Robinson equation of state is used for the calculation of fugacity. To model t...
