Optimizing Early Injection Strategy for Diesel PCCI Combustion

SAE Technical Paper Series, 2009
<div class="htmlview paragraph">A low swirl, low compression ratio engine with narrow fuel spray angle injector was used to investigate the cylinder wall wetting process of early direct injection strategies. A methodology was developed in order to detect liquid fuel impingement on the cylinder wall oil film.</div> <div class="htmlview ...

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

A Numerical Simulation of Fuel Premixing for PCCI Combustion by Direct Injection

ASME 2011 Power Conference, Volume 1, 2011
Diesel engine has some advantages that thermal efficiency is high and control response is fast. On the other hand, more particulate matter (PM) and nitrogen oxide (NOx) are contained in the exhaust gas of diesel engine. Premixed charge compression ignition (PCCI) combustion is proposed to reduce the PM and NOx.

Study of Fuel Distribution on Diesel PCCI Combustion by Development of a New Characteristic-Time Combustion Model

SAE International Journal of Fuels and Lubricants, 2008
<div class="htmlview paragraph">In order to understand premixed charge compression ignition (PCCI) combustion, a new combustion model of kinetic-and-turbulent characteristic-time has been developed. A ununiformity function <i>H</i>(ϕ)was presented by analysis of the effect of fuel/air distributions on the role of turbulent timescale ...

Premixed-Diffusive Multizone Model for Combustion Diagnostics in Conventional and PCCI Diesel Engines

Journal of Engineering for Gas Turbines and Power, 2011
A new multizone premixed-diffusive combustion model has been developed, assessed, and applied to diagnose the burning process and emission formation in a conventional and in a premixed charge compression ignition (PCCI) diesel engine. The model is based on the Dec conceptual scheme, which considers combustion as a two-stage quasi-steady process: All ...
