Title: Fuel injection pump amount setting detection for IC engine
Inventor: OISHI TAKASHI
IPC: F02B3/06
Filed: 1997-09-17
Abstract: The IC engine has fuel injection with the amount of fuel injected determined by the mechanical position of a fuel control element using a position sensor. To correctly characterise the fuel control unit the output of the position sensor is recorded at idling setting and at full torque setting. The control system calculates a relation between the sensor output and the amount of fuel injected. This corrected relation is used for the whole range of engine torque. The self-correcting control enables the different friction effects on different engines to be eliminated and to achieve an accurate control for the amounts of fuel injected.
