摘要： A fuel injector includes a nozzle body, and spray ducts coupled to the nozzle body and in spray path alignment with spray orifices therein. A nozzle check is movable within the nozzle body to open and close the spray orifices. Each of the spray ducts defines a duct center axis, and includes a center body forming, together with a duct inner surface, a spray jet passage circumferential of the duct center axis and reduced in area in a direction of spray jet advancement from the nozzle body.

The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

摘要： In an in-cylinder injection type multicylinder internal combustion engine for uneven interval firing, including a plurality of air-fuel mixture injection valves for directly injecting an air-fuel mixture into a combustion chamber of each cylinder, the air-fuel mixture injection valves being mounted on a multicylinder engine body and each having a fuel injection valve and an air injection valve, and an air pump actuatable by power transmitted from a crankshaft for discharging compressed air. The air pump is connected in common to the air-fuel mixture injection valves with the injection pressure of the air-fuel mixture injection valves in each cylinder being prevented from changing for good combustibility. The discharge timing of the air pump is set out of synchronism with the injection timings of the fuel injection valves and the air injection valves of all the cylinders.
