Experimental Characterization of Flat-Spray Injector for Gasoline Direct-Injection Engines

Characterisation of Particulate Matter Emitted from Aviation Gas Turbines and Spray-Guided Direct Injection Gasoline Engines

Combustion Modeling for Modern Direct Injection Diesel Engines

In order to comply with stringent pollutant emissions regulations, a detailed analysis of the engine combustion and emission is required. In this field, computational tools like CFD and engine cycle simulation play a fundamental role. Therefore, the goal of the present work is to simulate a high speed DI diesel engine and study the combustion and major diesel engine emissions with more deta...

Introducing of the propagation criterion and investigation of that for near vacuum chamber pressures for multi hole gasoline direct injector spray

with developing of optical technologies, using of different imaging methods to study various properties of gasoline direct injection spray is under development. Scope of this article is  to study the effect of overall spray angle and spray projected area for determination of spray propagation and investigate the effectiveness of this criterion.  The injector was a multi-hole direct injection in...

Hybrid Command Governors for Idle Speed Control in Gasoline Direct Injection Engines

Experimental investigation on the effect of injection pressure and injector installation angle on the penetration of the gasoline port fuel injector using high speed imaging method

The development of spray is one of the important factors effecting the combustion of PFI engines. This research was carried out in order to investigate some of the spray characteristics from PFI injector. In this study, the injector flux was investigated by a mass method and equations for it were presented. The results showed that in the pressure interval (2 to 6 bar), the relation of flux with...
