NOx and N2O formation in HCCI engines

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">Calculations using homogeneous and stochastic reactor models were performed in order to find an explanation to observed properties of NOx HCCI engines. It was found that for moderate NOx levels, N2O reactions play an important role in the NOx formation.

Grey-box modeling of HCCI engines

Applied Thermal Engineering, 2014
Abstract Homogenous Charge Compression Ignition (HCCI) holds promise to increase indicated thermal efficiency and reduce Nitrogen Oxides (NOx) and Particulate Matter (PM) emissions from internal combustion engines. Lack of a direct means to initiate the combustion and high levels of Total Hydrocarbon (THC) and Carbon Monoxide (CO) emissions are major

Research Testbed for HCCI Engine

2015
Within the project Experimentally Supported Development of Advanced Internal Combustion Engine Models (ExDAM) a new engine testbed is designed. During a phase of the testbed conceptual design, it has been concluded that the existing eddy current dyno is inadequate for planned tasks, so decision was made to build a new testbed with the AC dyno.

Cycle-to-Cycle Control of HCCI Engines

Dynamic Systems and Control, Volumes 1 and 2, 2003
With stated benefits ranging from increased thermal efficiency to significantly reduced NOx emissions, Homogeneous Charge Compression Ignition (HCCI) represents a promising combustion strategy for future engines. When achieved by reinducting exhaust gas with a variable valve actuation (VVA) system, however, HCCI possesses nonlinear cycle-to-cycle ...

Engine Modeling of HCCI Transient Operations

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">Control strategies for HCCI (Homogeneous Charge Compression Ignition) operation in 4-cylinder, 4-stroke engines were investigated using a simple engine model, which is composed of intake, combustion and gas exchange sub-models.

NOx formation inside HCCI engines

American Journal of Scientific and Industrial Research, 2010
A multizones modeling of the combustion characteristics of the spark assisted homogeneous charge compression ignition (HCCI) engine is performed. The main aim of this work is to deduce the simulation to reveal the in-cylinder conditions prevailing during the spark assisted HCCI combustion which is difficult to obtain experimentally.
