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).

摘要： The invention relates to a system which detects droplets (12) on a translucent surface (14) having a camera (16) which, upon activation, acquires an image of a portion of the surface (14). A radiation source (22), upon activation, illuminates the portion of the translucent surface (14) while a control circuit selectively activates both the camera (16) and the radiation source(22). A processor receives a captured image from the camera (16) and, through image processing, generates an output signal representative of the number of droplets (12) on the portion of the translucent surface (14).

摘要： An apparatus (20) for performing computed tomography having a radiation source (22, 162) and at least one radiation detector (24, 164) spaced from the radiation source (22, 162) and which generates an output signal (26, 28) representative of the strength of the received radiation from the radiation source (22, 162). A part support (30) for holding a plurality of parts is positioned in between the radiation source and the detectors (24, 164). The part support (30) is rotatably mounted about an axis (38) generally perpendicular to a vector between the radiation source (22, 162) and the detectors (24, 164) so that, upon rotation of the part support (30), the radiation detectors (24, 164) generate an output signal corresponding to the internal structure of parts (32) supported on the part support (30). A computer system (40) receives the output signals from the detectors and, under program control, generates a report of the internal structure of the parts (32) on the part support.

摘要： A method and a system are disclosed for identifying a gas type. The system includes a first sensor in contact with the gas and which produces a first electrical output signal indicative of a first condition of the gas. Similarly, a second sensor is also in contact with the gas and produces a second electrical output signal indicative of a second condition of the gas. A processor receives the output signals as input signals from the first and second sensors and determines the type of gas by calculation or from lookup tables stored in memory accessible to the processor. The first and second conditions of the gas are selected from the group of temperature, mass flow rate, temperature and pressure.
