Abstract
An internal combustion engine () comprises a fuel injection valve () which supplies a first fuel having a higher self-ignitability than gasoline and a second fuel having a higher combustion speed than gasoline such that an air-fuel mixture containing the first fuel and the second fuel is formed in a combustion chamber (), a spark plug () which ignites the air-fuel mixture, and a programmable controller () programmed to control supply proportions of the first fuel and the second fuel such that the ignited air-fuel mixture undergoes flame propagation combustion and then undergoes self-ignition combustion. Thus, a reduction in emissions can be achieved, and high thermal efficiency can be realized through the self-ignition combustion.
