ABSTRACT:
An internal combustion engine having two intake valves arranged in respective intake passages for each cylinder, wherein, a first intake passage is arranged to cause a swirl of intake air in the combustion chamber and a fuel injector is arranged in this intake passage, and a flow control valve is arranged in the second intake passage to close same when the engine load is low. An EGR passage is provided with an outlet in the second intake passage at a position between the second intake valve and the flow control valve, and the EGR gas is thus delivered to a volume enclosed in the second intake passage between the second intake valve and the flow control valve and remains there while these valves are closed. Then, when the second intake valve is open, the EGR gas slowly flows into the combustion chamber and floats toward and is collected at the upper region in the combustion chamber, while fuel flows smoothly into the combustion chamber, together with intake air, through the first intake passage.
