Abstract: (7407 Views)
Natural gas characteristics make it an attractive choice for replacing with oil fuels which causes climatic problems and environmental pollutions in the world. Generally, using natural gas in an internal combustion engine leads to lower volumetric efficiency of the engine, but gas direct injection technology would improve volumetric efficiency. Furthermore, more research is essential for improving the effectiveness of direct injection engines. A partially stratified charge is an appropriate idea for combustion efficiency improvement in direct injection engines. In the present study, a port injection engine is converted to direct injection engine and feasibility and condition of partially stratified mixture formation are investigated. Also, its effects on combustion and efficiency of the engine, with regards to location and injection timing of injector are noticed. Numerically simulation of current study shows that the formation of partially stratified charge, because of using air-guided method and located injector between air intake valves, is so hard and inaccessible. The high momentum of CNG jet makes a rapid motion of injected gas fuel and is not able to perform an appropriate mixture of air and fuel. Accordingly, an increase in air and fuel ratio is locally seen in the combustion chamber as this causes a drop in combustion efficiency. Although the increase in flame propagation and heat release can be expressed as results of this study, however, the benefits of rapid burning of CNG combustion due to the problems that are mentioned are not so impressive.
