Abstract
An internal combustion engine having a plurality of banks; each having a cylinder provided to said banks comprising: an intake valve provided between said cylinder and an intake manifold a camshaft opening and closing said intake valve by means of mechanical power of said internal combustion engine; and a changing unit changing, according to an operating state of said internal combustion engine a phase angle of said camshaft said phase angle corresponding to a closing timing of said intake valve said banks differing from each other in most retarded phase angle changed by said changing unit.

An internal combustion engine having a plurality of banks each having a cylinder provided to said banks, comprising:
- an intake valve provided between said cylinder and an intake manifold;
- a camshaft opening and closing said intake valve by means of mechanical power of said internal combustion engine;
- and
- a changing unit changing, according to an operating state of said internal combustion engine, a phase angle of said camshaft, said phase angle corresponding to a closing timing of said intake valve,
- said banks differing from each other in most retarded phase angle changed by said changing unit, and
- when said internal combustion engine is started, an in-cylinder pressure of a first bank of said plurality of banks that is determined based on a phase angle of said first bank is different from an in-cylinder pressure of a second bank different from said first bank that is determined based on a phase angle of said second bank.
