There is provided efficient compression auto-ignition combustion over intermediate load range extended towards a low and high load range. An internal combustion engine enables compression auto-ignition combustion by securing a so-called sealed duration created by negative valve overlap. It includes a cylinder head, a cylinder, a piston in the cylinder having a top coupled to the cylinder head, a combustion chamber between an inner surface of a cylinder head and a top of the piston, and intake and exhaust valves. Two intake valves are arranged per each combustion chamber and made to differ in valve lift. |
