Expanding the operating range of homogeneous charge compression ignition-spark ignition dual-mode engines in the homogeneous charge compression ignition mode

International Journal of Engine Research, 2005
Vehicle fuel economy benefit through the use of homogeneous charge compression ignition (HCCI) engine technology depends on the range of HCCI operating conditions. The range of HCCI operating conditions also determines the frequency of combustion mode transition over vehicle drive cycles.

Compression-Ignited Homogeneous Charge Combustion

SAE Technical Paper Series, 1983
<div class="htmlview paragraph">Experimentally obtained energy release results, a semi-empirical ignition model, and an empirical energy release equation developed during this research were used to evaluate the combustion of compression-ignited homogeneous mixtures of fuel, air, and exhaust products in a CFR engine. A systematic study was carried

Homogeneous charge compression ignition engine-out emission-does flame propagation occur in homogeneous charge compression ignition?

International Journal of Engine Research, 2002
Engine-out emissions data [CO, CO 2 , speciated hydrocarbons (HC), and particulate matter (size and number density)] were obtained from a single-cylinder, 660 cm 3 , homogeneous charge compression ignition (HCCI) engine operated on gasoline fuel using ...

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.
