Journal ArticleDOI
Numerical and experimental investigation on combustion characteristics of a spark ignition engine with an early intake valve closing load control
TL;DR: In this paper, a new intake port configuration has been designed, analyzed by means of 3D CFD simulation and experimentally tested on a turbocharged Spark Ignition (SI) engine, with the aim of addressing the issue of the poor in-cylinder turbulence levels which are typical of the Early-Intake-Valve-Closing (EIVC) strategies adopted in VVA systems at part load to reduce pumping losses.
Proceedings ArticleDOI
Experimental Investigation on Early and Late Intake Valve Closures for Knock Mitigation Through Miller Cycle in a Downsized Turbocharged Engine
TL;DR: In this paper, both EIVC and LIVC strategies have been examined aiming to achieve possible improvements for knock mitigation for turbocharged downsized spark ignition engine, and after some preliminary investigations confirmed that the latter was more effective than the former for this goal.
Journal ArticleDOI
Engine displacement modularity for enhancing automotive s.i. engines efficiency at part load
TL;DR: In this paper, the effects and possible benefits of cylinder deactivation on a four cylinder turbocharged downsized gasoline engine equipped with MultiAir VVA system were experimentally investigated, aiming to obtain further reductions of pumping losses beyond those achievable through normally adopted Early Intake Valve Closure (EIVC) strategies.
Patent
Internal combustion engine with cylinders which can be deactivated, in which the deactivated cylinders are used as pumps for recirculating exhaust gases into the active cylinders, and method for controlling this engine
TL;DR: In this article, an internal-combustion engine provided with variable actuation of the intake valves (6) of the cylinders (I, II, III, IV), some of said cylinders (II, III) are deactivated in given conditions of operation by interrupting the supply of fuel.
Proceedings ArticleDOI
Effects of Different Geometries of the Cylinder Head on the Combustion Characteristics of a VVA Gasoline Engine
TL;DR: In this paper, two different modifications of the baseline cylinder head configuration have been designed and experimentally tested on a MultiAir turbocharged gasoline engine, in order to address the issue of the poor in-cylinder turbulence levels which are typical of the Early-Intake-Valve-Closing (EIVC) strategies which are adopted in Variable Valve Actuation systems at part load to reduce pumping losses.
