摘要： A fuel injection system for an internal combustion engine wherein an oxygen sensor for detecting a limit electric current is employed for providing a signal indicating an oxygen partial pressure in the gas introduced into the engine. The sensor detects an amount of air newly introduced into the engine. In addition to a map for calculating a basic fuel injection amount from the oxygen partial pressure, a second map is provided for calculating the basic fuel amount from a parameter such as a degree of opening of the throttle valve. A degree of activation of the oxygen sensor is determined by detecting the impedance of the sensor. When it is determined that the oxygen sensor is not activated, the second map is employed in place of the first map to calculate the basic fuel amount based on the degree of opening of the throttle valve.
摘要翻译：一种用于内燃机的燃料喷射系统，其中采用用于检测极限电流的氧传感器，以提供指示引入发动机的气体中的氧气分压的信号。传感器检测新引入发动机的空气量。除了用于从氧分压计算基本燃料喷射量的地图之外，还提供第二图，用于根据诸如节流阀的开度的参数来计算基本燃料量。通过检测传感器的阻抗来确定氧传感器的激活程度。当确定氧传感器未被激活时，采用第二图来代替第一映射，以基于节气门的打开程度来计算基本燃料量。

摘要： A fuel injector comprising a pair of air passages which are joined at the nozzle opening, whereby fuel injected from the fuel supply bore is joined with the airstreams flowing in the air passages. At this time, the fuel is carried by the airstreams and thus flows through the air passages at a high speed, and accordingly, the fuel is caused to impinge against the inner wall of the nozzle opening at a high speed.
