It is well known that direct injection (DI) is a technology enabler for stratified combustion in spark-ignition (SI) engines. At full load or wide-open throttle (WOT), partial charge stratification ca....
Recent years have witnessed a dramatic increase in global ethanol production, while cellulosic feedstock or the algae-based production approach make more sustainable ethanol production foreseeable in ....
This paper presents the results of part of the research activity carried out by the Politecnico di Torino and AVL List GmbH as part of the European Community InGAS Collaborative Project. The work was ....
In this work a numerical analysis of multiple-injection strategy in homogeneous operation in DISI engines is presented. Moving toward Euro 6 emission standards, one of the main challenges for GDI engi....
Cycle-to-cycle variations of combustion processes strongly affect the emissions, specific fuel consumption as well as work output. Especially Direct Injection Spark-Ignition (DISI) engines are very se....
Of late direct injection engines are replacing carbureted and port-injected engines due to their high thermal efficiency and fuel economy. One of the reasons for the increased fuel economy is the ultr....
Heavy fuel engines have typically been limited to large, heavy compression ignition engines. However, with the push by the US military to use a common fuel (JP5/JP8/diesel) there is a need to develop ....
Spray penetration and mixture formation in GDI engines are crucial to a reliable ignition and the subsequent combustion. For the prediction of the mixture formation process, computational fluid dynami....
Numerical simulation has been widely used in the engine development process to improve the development quality, especially in the area of in-cylinder flow and fuel evaporation. In this paper, a fuel s....
Advanced combustion strategies for direct injection gasoline engines require high performance fuel injectors. They must perform precise fuel metering, enhanced linear flow range and multi-pulse inject....
Gasoline direct injection provides reduced engine emissions, increased power, and increased fuel economy as compared to port fuel injection (PFI). Reduced emissions are largely due to starting the eng....
The improvement of spray atomization and penetration characteristics of GDI multi-hole injector sprays is a major component of the engine combustion developments, in order to achieve the fuel economy ....
Combustion in direct injection spark ignition (DISI) engines is strongly influenced by the in-cylinder charge motion. The charge motion depends both on the injection strategy as well as the geometry o....
