Abstract: Due to the high transiency and high voltage characteristics of spark ignition (SI), precise measurements are in demand for efficient ignition in future clean combustion engines. The practical challenges of SI systems arise ...

Abstract: Homogeneous charge compression ignition (HCCI) combustion in diesel engines can provide cleaner operation with ultralow NOx and soot emissions. While HCCI combustion has generated significant attention in the last decade, ...

Abstract: The characteristics of combustion, emissions, and thermal efficiency of a diesel engine with direct injection (DI) neat nbutanol were investigated. The engine ran at a load of 6.5–8.0 bar indicated mean effective ...

Abstract: Heavy EGR required on diesel engines for future emission regulation compliance has posed a big challenge to conventional turbocharger technology for high efficiency and wide operation range. This study, as part of the U.S. ...

Abstract: Worldwide research and development programs aim to reduce harmful emissions from transportation vehicles. Soft sensors have shown great potentials to reduce cost and improve onboard diagnosis for vehicle emission control. ...

Abstract: Previous research indicates that the low temperature combustion (LTC) is capable of producing ultralow nitrogen oxides (NOx) and soot emissions. The LTC in diesel engines can be enabled by the use of heavy exhaust gas ...
