The head has an intake passage therein and an intake valve interposed the intake passage and the cylinder. The head has a recirculation passage therein having an exhaust gas recirculation valve interposed the intake passage and the cylinder. And, the exhaust gas recirculation valve is movable between a closed position and an open position in which an exhaust gas is communicated from the cylinder to the intake passage.
