ENGINE GOVERNOR WITH DUAL REGULATION

摘要

Engine Governor With Dual Regulation A governor for providing at least two different amounts of regulation for an internal combustion engine including a fuel injection system. The governor includes a rotatable flyweight assembly mechanically connected to the engine to be driven thereby. A first spring may be compressed by the flyweight assembly proportional to engine speed. The flyweight assembly is connected to the engine fuel injection system by a rack and a control lever abuts the first spring, in opposition to the flyweight assembly. The governor includes a second compressible spring along with an actuator for selectively engaging and disengaging the control lever. One amount of regulation is provided when the second spring is engaged with the control lever and a second, different amount of regulation is provided when the second spring is disengaged from the control lever, with engine governing being provided solely by the first spring.
