Fuel injection system for an internal combustion engine
This patent describes a fuel injection system for four-cylinder internal combustion engine having a common intake manifold connected to the cylinders of the engine on both sides of the engine with respective branches of respective common intake manifold sections of the common intake manifold being connected with adjacent cylinders on both sides of the engine respectively via fuel-air intake valves of the cylinders, respectively, the fuel-air intake valves of the respective cylinders opening and closing in predetermined sequential order defining a cycle, and ignition in the respective cylinders occurring at respective predetermined timings, the improvement comprising at least one fuel injector being disposed in each of the common intake manifold sections, the fuel injectors being operable by a fuel injection signal so as to permit injection of fuel into the manifold sections, and means for generating the fuel injection signal for opening the fuel injectors when three of the intake valves of the cylinders are closed and before beginning of closing of the remaining intake valve of the remaining cylinder.
