Hybrid multi-objective MPC for fuel-efficient PCCI engine control

2015 European Control Conference (ECC), 2015
In the present paper the closed-loop control of an innovative combustion engine is investigated. The investigated combustion engine is characterized by the ability of handling different combustion modes, such as Premixed Charge Compression Ignition (PCCI), which are applied depending on the operating point.

Investigation of the Optimal Injection Conditions for a PCCI Diesel Engine

ASME 2012 Internal Combustion Engine Division Fall Technical Conference, 2012
Premixed charge compression ignition (PCCI) engines have the potential with their attractive advanced combustion process to achieve a more homogeneous mixture and a lower peak combustion temperature resulting in both lower nitrogen oxides (NOx) and diesel particulate matter (PM) emissions.

Miller-PCCI Combustion in an HSDI Diesel Engine with VVT

SAE International Journal of Engines, 2008
<div class="htmlview paragraph">A variable valve timing (VVT) mechanism has been applied in a high-speed direct injection (HSDI) diesel engine. The effective compression ratio (ε_eff) was lowered by means of late intake valve closing (LIVC), while keeping the expansion ratio constant.

Model-Based Optimal Control for PCCI Combustion Engines

IFAC Proceedings Volumes, 2010
Abstract New combustion methods for engines have been recently researched very intensively. In diesel engines, the homogenisation of the air-fuel mixture by early fuel injection has significant effects on emission reduction. The paper presents a model-based optimal control strategy for premixed charge compression ignition (PCCI) low temperature ...

Fuel Property Effects on PCCI Combustion in a Heavy-Duty Diesel Engine

Journal of Engineering for Gas Turbines and Power, 2010
An experimental study was performed to investigate fuel property effects on premixed charge compression ignition (PCCI) combustion in a heavy-duty diesel engine. A matrix of research diesel fuels designed by the Coordinating Research Council, referred to as the Fuels for Advanced Combustion Engines (FACE), was used. The fuel matrix design covers a wide

Effects of Fuel Volatility on Combustion Characteristics of PCCI Diesel Engine

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">In PCCI diesel engine, the fuel is injected much earlier than the injection timing of conventional diesel engines. Exhaust-emission improvements are attained by the lean-premixed combustion. It is expected that fuel properties influence mixture formation and combustion characteristics. In this research, experiments
