  • Engine controller with air meter compensation during engine crank
    Patent number: 5623908
    Abstract: An engine controller compensates for changes in air pressure and intake of the engine during engine crank which are caused by injection of fuel into the intake. The engine controller compares rotational speed of the engine to a threshold value and determines a cylinder air charge value in a first manner if the engine speed is greater than or equal to the threshold value. If the engine speed is less than the threshold value then the reliability of an air meter positioned in the intake is tested and if the air meter is determined to be of sufficient reliability then the cylinder air charge is determined in a second manner. If the air meter is determined to be unreliable then the operability of a throttle position sensor is determined and if the throttle position sensor is determined to be operable then the cylinder air charge is determined in a third manner.
