Homogeneous Charge Compression Ignition of Diesel Fuel
SAE Technical Paper Series, 1996<div class="htmlview paragraph">A single-cylinder, direct-injection diesel engine was modified to operate on compression ignition of homogenous mixtures of diesel fuel and air. Previous work has indicated that extremely low emissions and high efficiencies are possible if ignition of homogeneous fuel-air mixtures is accomplished.

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.

Homogeneous charge compression ignition with synthetic fuels
MTZ worldwide, 2005Homogeneous Charge Compression Ignition (HCCI) represents a promising alternative mode of combustion to simultaneously reduce engine-out emissions of particulates and nitrogen oxides. In this article, the effect of different, mostly synthetic fuels on the HCCI combustion process and emissions will be discussed.

Active valvetrain for homogeneous charge compression ignition
International Journal of Engine Research, 2005Homogeneous charge compression ignition (HCCI), also known as controlled autoignition (CAI) or the premixed charge compression ignition (PCCI) engine concept, has the potential to be highly efficient and to produce low NO x , carbon dioxide, and particulate matter emissions.

Torque-oriented control of an homogeneous charge compression ignition vehicle
2008 47th IEEE Conference on Decision and Control, 2008This paper presents a torque-oriented structure designed for a diesel homogeneous combustion compression ignition (HCCI) engine control. The proposed controllers are designed to get the maximum benefit provided by the HCCI combustion system. The engine control issues comes from the sensitivity of the HCCI combustion system and from the complexity of ...

Adaptive control of homogeneous charge compression ignition (HCCI) engines
2012 American Control Conference (ACC), 2012This paper presents an adaptive controller which maintains consistent ignition timing control of a gasoline homogeneous charge compression ignition (HCCI) engine with high dilution in the presence of uncertainty or unknown variation in plant parameters such as exhaust runner wall temperature and cylinder charge properties. The control of the combustion

Performance of a homogeneous charge compression ignition engine fuelled with gasoline
International Journal of Vehicle Design, 2012The performance of a Homogeneous Charge Compression Ignition (HCCI) engine fuelled with gasoline by means of a stochastic reactor model is investigated. A zero-dimensional simulation code called Stochastic Reactor Model (SRM) for combustion and convective heat transfer is applied.

Homogeneous charge compression ignition (HCCI) is known as an advanced combustion system. Due to cost limitations, small-scale engines are not equipped with features and devices, such as variable valve timing, intake heater, etc. which facilitate HCCI combustion. This study implemented HCCI on two small-scale engines, 150 cc spark ignition (SI) and 224
