| Abstract(E) | Split injection has shown its potential to improve combustion performance and reduce exhaust emissions. To further clarify the effects of injection pressure and injection interval on suppressing soot generation, the experimental study on diesel spray/wall interaction and combustion process was conducted using a rapid compression and expansion machine. Results showed, high injection pressure reduced soot generation by improving the air/fuel mixture uniformity. In addition, soot particles were captured firstly formatted at the flame interior resulting from the lack of oxygen in this region, and then gradually oxidated at the flame external as the high-temperature flame contacting with the ambient gas. |
