Document Type and Number:
Japanese Patent JP2983547
Kind Code:
B2
Abstract:
A fuel injection pump for internal combustion engines, which has a pump interior and a control mechanism chamber separate from it, with a control mechanism for actuating a quantity adjusting device determining the fuel injection quantity, is provided with an electrical temperature sensor, to compensate for the effect of temperature on the metered fuel quantity. The output signal of the temperature sensor is included as a correction variable in the control variable for the control mechanism. To assure accurate temperature measurement without delay, and for easy access to the temperature sensor for servicing, the temperature sensor is disposed in the control mechanism chamber and, with a temperature-sensitive sensor element, preferably an NTC resistor, dips into a permanent fuel flow diverted from the pump interior. The electrical connecting lines of the temperature sensor are extended to a circuit board on which the connecting lines for the electric control mechanism are also located, in the control mechanism chamber and bonded thereto.
