RISOptical Investigation of the Effects of Ethanol/Gasoline Blends on Spark Assisted HCCI
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spark assist (SA) has been demonstrated to extend the operating limits of homogeneous charge compression ignition (HCCI) modes of engine operation. This experimental investigation focuses on the effects of 100% indolene ...
In-Cylinder Imaging and Emissions Measurements of Cold-Start Split Injection Strategies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Strategies to mitigate cold-start emissions are critical to meet stringent standards for particulate and regulated gaseous emissions from direct injection spark ignition (DISI) engines. The objective of the current work ...
The Impact of Low Octane Primary Reference Fuel on HCCI Combustion Burn Rates: The Role of Thermal Stratification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new experimental method was developed which isolated charge composition effects for wide levels of internal exhaust gas recirculation (iEGR) at constant total EGR (tEGR) for homogeneous charge compression ignition (HCCI) ...
Genetic Optimization for Engine Combustion System Calibration: A Case Study of Optimization Performance Sensitivity to Algorithm Search Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of genetic optimization algorithms (GOA) has been shown to significantly reduce the resource intensity of engine calibration, motivating investigation into the development of these methods. The objective of this ...
