    摘要： In a port fuel injection lean burn engine, attaching of fuel spray onto a wall surface, which is a problem at atomizing injected fuel, is reduced, and the quality and shaping state of the mixed gas in cylinders of the engine is improved.
    The engine comprises a fuel injector (1); an intake valve (6) for opening and closing an intake port; and an intake air flow control device (10). The injected fuel is shaped in a low penetration fuel spray when the engine is operated in a low load and low rotation speed, and the injected fuel is shaped in a high penetration fuel spray when the engine is operated in a high load and high rotation speed, the fuel is injected in synchronism with the intake stroke of the engine, and is transported by the air flow flowing through the intake air flow control device (10) to suppress attaching of fuel spray onto a wall surface.

    摘要： The invention relates to an engine startup fuel control system for use with an internal combustion engine (20) of the type having a plurality of combustion chambers (30), an air intake passage (34) fluidly connected to each combustion chamber (30) and a source of fuel (44). The system includes a multipoint fuel injector (42) associated with each combustion chamber (30) in which the multipoint fuel injector (42) has an inlet connected to the fuel source (44) and an outlet fluidly connected to the intake air passageway (34) adjacent its associated combustion chamber (30). A cold start fuel injector (60) also has an inlet (62) connected to the fuel source (44) and an outlet (64) connected through a cold start passageway (68) with each combustion chamber (30). A processing circuit (48) selectively activates the multipoint fuel injectors (42) as well as the cold start fuel injector (60). The processing circuit (48) determines the air/fuel mixture introduced by the cold start fuel injector (60) into each combustion chamber (30) during engine startup and then selectively activates the multipoint fuel injectors (42) to achieve a predetermined air/fuel mixture in each combustion chamber (30) during engine startup. The processing circuit (48) also variably retards the ignition of the combustion charge within at least one of the combustion chambers (30) to achieve faster heating of a catalytic converter. Furthermore, the cold start fuel injector (60) is optionally activated in a plurality of spaced sub-pulses (112) for each combustion charge provided to each combustion chamber (30).
