g. Amount of Injection Quantity by Atmospheric Air Pressure Correction With using atmospheric air pressure sensor signal, the maximum injection quantity curve is corrected as shown in the figure below. %QSYRXSJ%XQSWTLIVMG%MV4VIWWYVI'SVVIGXMSR 5) )RKMRI7TIIH h. Idle Speed Control System (ISC) Controls the idle speed by regulating the injection quantity in order to match the target speed, which has been calculated by the computer, with the actual speed. The functions of the ISC can be broadly divided into the following two items: (1) Auto ISC Controls the idle speed in accordance with the water temperature.
