MIT Unveils Dual-Mode SI/HCCI Concept That Could Boost Gasoline Engine Fuel Economy

摘要

Massachusetts Institute of Technology (MIT) researchers on July 23 unveiled a dual-mode combustion engine concept that eventually could help gasoline engines become more fuel-efficient.In a paper presented to Society of Automotive Engineers fuels & lubes conference in Japan this month, the MIT researchers said the scheme could allow switching between conventional spark-ignited (SI) gasoline combustion and homogenous charge compression ignition (HCCI), which more resembles diesel combustion.
