RISEffects of Charge Preheating Methods on the Combustion Phasing Limitations of an HCCI Engine With Negative Valve Overlap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Homogeneous charge compression ignition (HCCI) has the potential to reduce both fuel consumption and NOx emissions compared to normal spark-ignited (SI) combustion. For a relatively low compression ...
Assessment of Residual Mass Estimation Methods for Cylinder Pressure Heat Release Analysis of HCCI Engines With Negative Valve Overlap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Increased residual levels in homogeneous charge compression ignition (HCCI) engines employing valve strategies such as recompression or negative valve overlap (NVO) imply that accurate estimation ...
Knock In Various Combustion Modes in a Gasoline-Fueled Automotive Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Homogeneous charge compression ignition (HCCI) offers great potential for improved fuel economy and dramatically reduced NOx emissions, compared to typical spark ignition (SI) combustion. However, ...
