摘要： An engine (10) includes an electronically controlled mixing ratio control valve (24) with a first inlet (25) fluidly connected to a source of gasoline (20), and a second inlet (26) fluidly connected to a source of compression ignition fuel (22), such as distillate diesel fuel. An outlet (42) from the mixing ratio control valve (24) is fluidly connected to a fuel inlet (40) of at least one fuel injector (17). The mixing ratio control valve (24) varies a mixture ratio of gasoline to compression ignition fuel responsive to a control signal communicated from an electronic controller (18). The blended fuel may be pressurized to injection levels in the fuel injector (17), and injected directly into the engine (10) cylinder (12). The compression ignition fuel is compression ignited, which in turn ignites the gasoline to produce a lower and better combination of undesirable emissions as a result of the combustion process.
