Flow Dynamics of Charge Stratification in Small GDI Two-Stroke Engines
No full textDirect high-pressure liquid fuel injection is able to control the mixing process inside the cylinder for getting either stratified charge at partial loads or quasi-homogeneous conditions, as it is required at full load. This paper shows the development of this solution for small two-stoke engines, using multidimensional modelling. The aim is investigating how the design of scavenging ducts and combustion chamber influences charge stratification behaviour, taking into account fuel distribution and stratification stability varying engine load and speed

Numerical and Experimental Study of Direct Injection for Charge Stratification in a 200 cc Two-Stroke Motorcycle Engine
No full textThis paper shows a numerical and experimental study concerning liquid high-pressure direct injection with charge stratification in a 200 cm 3 two-stroke motorcycle engine.
Numerical predictions have been performed using KIVA-3v code with different combustion-chamber shapes and spray characteristics.
Experimental outcomes have substantially confirmed the predictions of computation and proved that injector characteristics are of the utmost importance to achieve satisfactory results
