Title:
FUEL LIMITING DEVICE FOR ENGINE WITH SUPERCHARGER
Document Type and Number:
Japanese Patent JP3433167
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To prevent black smoke emission and wasteful fuel consumption while ensuring starting performance of an engine in a simple, inexpensive constitution.
SOLUTION: By constituting a metering tool 21 of a fuel injection pump 20 of an engine E with a supercharger so that its metering movement is possible with a governor lever 14, and latching an output rod 30 of a booster 26 with a power point J of a rocking lever 31 supported by a rocking spindle Q, fuel increasing movement of the metering tool 21 is controlled at the point of force application K of the rocking lever 31, in conjunction with ascending delay of supercharged pressure P of the engine. A power point J of the rocking lever 31 is so constituted that it can be displaced to face the opposite direction by an actuator 40 mounted on the output rod 30 of a booster 26. When the engine starts, the actuator 40 does not operate, thereby releasing the fuel limiting function of the booster 26. After the engine starts, the fuel limiting function of the booster 26 is maintained.
