Induction arrangement for internal combustion engine having multiple inlet valves per cylinder

In an internal combustion engine

• a combustion chamber;
• an induction manifold;
• intake port means in communication with said induction manifold formed by a main section and first and second branch sections located downstream of said main section and separated one from the other by a partition wall extending toward said main section;
• first and second inlet valves for controlling fluid communication between said combustion chamber and said first and second branch sections, respectively;
• a fuel injector for injecting fuel into the main section of said intake port along a flow path toward said partition wall so that said fuel enters both said first and second branch sections;
• and
• a flow control valve disposed upstream of said first and second branch sections for control of flow of the entire volume of air from said induction manifold, said flow control valve including at least on aperture in a surface so that when the flow control valve assumes a closed position the flow of air which is inducted into the combustion chamber via the induction manifold follows a path of flow which is close to said partition wall to entrain the injected fuel and enter the combustion chamber in a manner which mixes the air and fuel.
