<P>PROBLEM TO BE SOLVED: To provide a controller for internal combustion engine which improves fuel consumption while preventing knocking. <P>SOLUTION: A controller (100) for an internal combustion engine (10) includes: a structure for reducing cooling loss in a cylinder head (12) by heat insulation of the cylinder head while securing cooling of a cylinder block (11); and an air current control valve (21) which controls a flow direction when mixed air obtained by mixing the fuel with air flows in a combustion chamber (14); and a control part (105) which controls aperture of the air current control valve so that the mixed air flowing in the combustion engine collides with the cylinder head when heavy fuel detection means (104) of detecting heavy fuel in the internal combustion engine detects the heavy fuel. <P>COPYRIGHT: (C)2013,JPO&INPIT |
