System Identification of Homogeneous Charge Compression Ignition (HCCI) Engine Dynamics
IFAC Proceedings Volumes, 2004Homogeneous Charge Compression Ignition (HCCI) combustion lacksdirect ignition timing control, instead the auto ignition depends on the operatingcondition. Since auto ignition of a homogeneous mixture is very sensitive tooperating condition a fast combustion timing control is necessary for reliableoperation, the ignition timing control design requiring

Closed‐loop combustion control of homogeneous charge compression ignition (HCCI) engine dynamics
International Journal of Adaptive Control and Signal Processing, 2004AbstractHomogeneous charge compression ignition (HCCI) is a hybrid of the spark ignition and compression ignition engine concepts. As in a spark ignition engine, a homogeneous fuel–air mixture is created in the inlet system. During the compression stroke the temperature of the mixture increases and reaches the point of auto ignition, just as in a ...

Homogeneous Charge Compression Ignition (HCCI) Combustion: Combustion Process and Control Strategies
International Journal of Frontiers in Sociology, 2021Homogeneous Charge Compression Ignition (HCCI), a low temperature combustion technology, is believed to be a promising technology due to low NOx and PM emissions and better fuel economy. HCCI combustion can realize homogeneous charge preparation in the cylinder and promote combustion auto-ignites in multiple spots by cooperative control of fuel ...

Combustion phasing and work output are the two critical indicators for achieving and maintaining homogeneous combustion for homogeneous charge compression ignition (HCCI) engines. However, the complicated thermodynamic process keeps the combustion phasing model from being explicit.

SAE Technical Paper Series, 2009
<div class="htmlview paragraph">The current direction of most published diesel HCCI research is mixture preparation using the direct injection – system, referred to as internal mixture formation. The alternative to the internal mixture formation is, predictably, external mixture formation.

Modeling and control of a heated air intake homogeneous charge compression ignition (HCCI) engine
Proceedings of the 2010 American Control Conference, 2010In this paper a statistical physics based mean value model (MVM) is introduced for a heated intake homogeneous charge compression ignition (HCCI) engine based on a previously developed crank angle resolved model [1] and validated. In this HCCI engine, regulation of combustion timing is based on manipulating the cylinder charge temperature through the ...

Homogeneous charge compression ignition (HCCI) combustion of polyoxymethylene dimethyl ethers (PODE)
Fuel, 2016Abstract Polyoxymethylene dimethyl ethers (PODE) are a promising alternative fuel for diesel engines. PODE have high volatility, high ignitability and high oxygen content, and is thus also an ideal additive fuel for blend and dual-fuel combustion due to its low-temperature chemistry.

Research on Gasoline Homogenous Charge Compression Ignition (HCCI) Engine
2016Homogenous charge compression ignition engine (HCCI) represents a new idea of combustion technology that combines the main advantages of the gasoline engines (the homogeneous charge) with the main advantages of the diesel engines (higher compression ratios which determinates higher efficiencies). An important advantage is the low temperature combustion
