Abstract
Each cylinder of a multi-valve engine is provided with a bifurcate induction port which has a partition wall; a fuel injector which injects fuel toward the partition wall so that fuel is distributed into the two branches which lead to the inlet valves; and a flow control valve is disposed upstream of the partition wall and formed with one or more apertures which when the valve is closed, direct a flow or flows of air which pass close to the partition wall, entrain the injected fuel and induce a turbulent mixing action which forms an ignitable cloud of air-fuel mixture in close proximity to the spark plug.
