INTERNAL COMBUSTION ENGINE
First Claim
1. 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.

Abstract
An internal combustion engine (100) comprises a fuel injection valve (21, 22) 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 (14), a spark plug (25) which ignites the air-fuel mixture, and a programmable controller (41) 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.

20. An internal combustion engine comprises:
-
means for supplying 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; means for igniting the air-fuel mixture so as to perform flame propagation combustion; and means for controlling 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.
