Combustion Processes

In order to promote the quality of mixture and improve the fuel spray spatial distribution, enhancing airflow movement in a combustion chamber, a new swirl chamber combustion system in DI (direct injection) diesel engines is proposed based on conical-spray. Numerical simulations have been conducted by using the FIRE v2008 code. Several different widths of passage and spray angles are investigated in a single cylinder 135 diesel engine. The combustion and emissions performance were investigated by different conical-spray nozzles and combustion chambers with a constant compression ratio. The results show that using this combustion system, the mixture formation and combustion processes have been improved by a certain longitudinal swirl when the air is squished into the swirl chamber through the relative narrow passage. Moreover, the formation of homogeneous mixture is accelerated and the combustion is improved compared with that of conventional combustion system. The cases show the passage width of 5mm and conical spray cone angle of 140° has a better performance in the new combustion system.

The intent of this paper is to summarize the state of knowledge on use of vegetable oils as diesel fuels. Fuel related properties are reviewed and compared with conventional diesel fuel. The use of neat vegetable oil (edible and/or nonedible), biodiesel and its blends in a diesel engine has been discussed. Performance and emission characteristics are highlighted. Suitability of different combustion chambers for diesel engine operation with vegetable oils is outlined. Techniques to decrease viscosities are discussed. An overview on current developments on the use of vegetable oils directly and indirectly in diesel engines is presented.
