RISSI–HCCI Mode Transitions Without Open-Loop Sequence Scheduling: Online Parameter Adaptation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A parameter adaptation method for a previously developed spark ignition (SI) to homogeneous charge compression ignition (HCCI) combustion mode transition control architecture is described. The goal of the adaptive method ...
SI-HCCI Mode Transitions Without Open-Loop Sequence Scheduling: Control Architecture and Experimental Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a model-based feedback control method to transition from spark ignition (SI) to homogeneous charge compression ignition (HCCI) combustion in gasoline engines. The purpose of the control structure is ...
Effect of Ambient Temperature and Humidity on Combustion and Emissions of a Spark-Assisted Compression Ignition Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spark-assisted compression ignition (SACI) offers more practical combustion phasing control and a lower pressure rise rate than homogeneous charge compression ignition (HCCI) combustion and improved thermal efficiency and ...
Fuel Economy of a Multimode Combustion Engine With Three Way Catalytic Converter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Highly diluted, low temperature homogeneous charge compression ignition (HCCI) combustion leads to ultralow levels of engineout NOx emissions. A standard drive cycle, however, would require switches between HCCI and ...
Particulate Matter Emission Comparison of Spark Ignition Direct Injection (SIDI) and Port Fuel Injection (PFI) Operation of a Boosted Gasoline Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spark ignition direct injection (SIDI) gasoline engines, especially in downsized boosted engine platforms, are increasing their market share relative to port fuel injection (PFI) engines in U.S., European and Chinese ...
Lean HCCI/Rich SACI Gasoline Combustion Cycling and Three Way Catalyst for Fuel Efficiency and NOx Reduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multimode combustion (MMC) concepts using homogeneous charge compression ignition (HCCI) gasoline combustion at low loads and spark assisted compression ignition (SACI) gasoline combustion at medium loads have the potential ...
