Effect of Direct Injection Diesel Engine Convert to Sequential Injection CNG Engine in Intake Port Gas Flow Pressure Profile
The one dimension computational model of a sequential injection engine, which runs on compressed natural gas (CNG) with spark ignition, is developed for this study, to simulate the performance of gas flow pressure profile, under various speed conditions. The computational model is used to simulate and study of the steady state and transient processes of the intake manifold. The sequential injec...
متن کاملA Cluster Nozzle Concept with high injection pressures for DI Diesel Engine
A combination of high pressure injection and small orifices will be one of strategies to achieve the lean combustion. But the small orifice tends to increase soot under high load conditions because of short spray tip penetration. For this reason, a cluster concept was proposed in this study. The difference of the cluster nozzle is that the cluster has several groups of orifices; each group cons...
متن کاملDual Fuelling of a Direct Injection Automotive Diesel Engine by Diesel and Compressed Natural Gas
Application of Compressed Natural Gas (CNG) in diesel engines has always been important, especially in the field of automotive engineering. This is due to easy accessibility, better mixing quality and good combustion characteristics of the CNG fuel. In this study the application of CNG fuel along with diesel oil in a heavy duty direct-injection automotive diesel engine is experimentally investi...
متن کاملDual-Fuelling of a Direct-Injection Automotive Diesel Engine by Diesel-Gas Method
Use of liquefied petroleum gas (LPG) in compression-ignition (C-I) engines has always been considered important in the diesel engineering field. This is due to its easy accessibility and good combustion characteristics. In this paper the application of LPG fuel along with diesel oil in a direct- injection automotive diesel engine is experimentally investigated. In order to convert the pure dies...
متن کاملInvestigation the effects of injection pressure and compressibility and nozzle entry in diesel injector nozzle’s flow
Investigating nozzle’s orifice flow is challenging both experimentally and theoretically. This paper focuses on simulating flow inside diesel injector nozzle via Ansys fluent v15. Validation is performed with experimental results from Winkhofler et al (2001). Several important parameters such as mass flow rate, velocity profiles and pressure profiles are used for this validation. Results includ...
