Progress and recent trends in homogeneous charge compression ignition (HCCI) engines

Progress in Energy and Combustion Science, 2009
HCCI combustion has been drawing the considerable attention due to high efficiency and lower nitrogen oxide (NOx) and particulate matter (PM) emissions. However, there are still tough challenges in the successful operation of HCCI engines, such as controlling the combustion phasing, extending the operating range, and high unburned hydrocarbon and CO ...

Homogeneous Charge Compression Ignition (HCCI) Engine

SAE International Journal of Fuels and Lubricants, 2009
<div class="htmlview paragraph">Ion sensors have been shown to be a low-cost and robust method of measuring start of combustion (SOC) in Homogeneous Charge Compression Ignition (HCCI) engines. The combustion event in an HCCI engine is governed by temperature sensitive chemical-kinetics and is highly fuel dependent.

Dynamics of Homogeneous Charge Compression Ignition (HCCI) Engines with High Dilution

2007 American Control Conference, 2007
This paper analyzes the stability of the autoignition process of homogeneous charge compression ignition (HCCI) engines in light of the cycle-to-cycle thermal feedback due to the high percentage of exhaust dilution. The influence of heat transfer and the cooling system on the system stability is investigated.
