Apparatus for adjusting fuel amount of diesel engine

摘要

An apparatus for adjusting the fuel amount of a diesel engine is capable of preventing a decrease in the accuracy of the adjustment of the fuel amount. An engine stop operation input portion 12 is installed in the slider 5 and an engine stop operation output portion 13 is opposite to the engine stop operation input portion 12. When an engine stop operation is performed, engine stop operation force 14 is inputted from the engine stop operation output portion 13 to the engine stop operation input portion 12 and the slider 5 slides in the direction of the decrease in the fuel amount with the governor lever 1 remained intact so that the engine is stopped. A virtual line 16 is assumed to pass through a central portion of the biasing spring 9 when seen from a direction parallel to the adjustment amount rack pin 8.

1. An apparatus for adjusting the fuel amount of a diesel engine comprising:
a base end portion 2 of a governor lever 1 of a mechanical governor being pivoted on a governor lever shaft 3, a slider 5 being slidingly mounted on a swing end portion 4 of the governor lever 1 in a direction of an increase and decrease in a fuel amount, and an adjustment amount rack pin 8 of a fuel injection pump 7 being engaged in a rack pin engagement portion 6 of the slider 5 so that the slider 5 is biased by a biasing spring 9 in the direction of the increase in the fuel amount, stoppers 10 installed in the governor lever 1 and locking portions 11 facing the stoppers 10 installed in the slider 5 so that the locking portions 11 are supported by the stoppers 10 and thus a movement of the slider 5 in the direction of the increase in the fuel amount is stopped, and an engine stop operation input portion 12 installed in the slider 5 and an engine stop operation output portion 13 opposite to the engine stop operation input portion 12, when an engine stop operation is performed, an engine stop operation force 14 is inputted from the engine stop operation output portion 13 to the engine stop operation input portion 12 and the slider 5 slides in the direction of the decrease in the fuel amount with the governor lever 1 remained intact so that the engine is stopped, and wherein a virtual line 16 is assumed to pass through a central portion of the biasing spring 9 when seen from a direction parallel to the adjustment amount rack pin 8, a shaft-distant side 30 spaced apart from the governor lever shaft 3 and a shaft-proximal side 31 proximal to the governor lever shaft 3 being divided on the basis of the virtual line 16, and the stoppers 10 being disposed in the shaft-distant side 30 and the shaft-proximal side 31, respectively.
