An electronically-controlled air injection system implemented in three different embodiments with respect to each cylinder. A first embodiment includes a T-adapter, an air solenoid, a fuel injector, and a control unit. The T-adapter receives pressurized fuel and pressurized air from an air solenoid, and outputs these to the fuel injector. The air solenoid controls the flow of air to the fuel injector via the control unit. The second embodiment includes a modified fuel injector, an air solenoid, and a control unit. The fuel injector is modified by forming therein an air passage and a communicating sac, wherein the sac communicates with the fuel valve. Compressed air is supplied through an air solenoid to the air passage. The third embodiment includes a modified cylinder head, an air solenoid, and a control unit. Compressed air is supplied through an air solenoid to at least one combustion chamber cylinder port in the cylinder head.
An electronically controlled air injection system for each cylinder of an internal combustion engine, said engine having a piston in each cylinder, at least one exhaust valve of each cylinder, and a source of pressurized fuel, said system comprising:
