Document Type and Number:
WIPO Patent Application WO/2016/117444
Kind Code:
A1
Abstract:
Provided is a flexible-fuel engine that makes it possible to use a fuel containing an alcohol as a fuel that is burned in a cylinder (11), wherein: the geometric compression ratio is set to 12 or more; engine starting is carried out using a fuel that contains an alcohol; and the intake valve closing timing at the time of engine starting is set to a timing that is more advanced than a first reference timing (L1), which is the most retarded timing from among intake valve closing timings at which the engine can be started even when fuel containing 100% alcohol is burned in the cylinder at a first intake temperature, and more retarded than a second reference timing (L2), which is the most advanced timing from among intake valve closing timings at which pre-ignition does not occur even when fuel containing 100% gasoline is burned during starting at a second intake temperature.
