A governor (11) for providing at least two different regulation factors for an internal combustion engine (10) including a fuel injection system (12).

A governor (11) for providing at least two different regulation factors for an internal combustion engine (10) including a fuel injection system (12). The governor (11) includes a rotatable flyweight assembly (18,20,22) adapted to be mechanically connected (24) to the engine (10) to be driven thereby. A first spring (28) may be compressed by the flyweight assembly (18,20,22) proportional to engine speed. The flyweight assembly (18,20,22) is adapted to be connected to the engine fuel injection system (12) by a rack (14) and a control level (34) abuts the first spring (28), in opposition to the flyweight assembly (18,20,22). The governor (11) includes a second compressible spring (70) along with an actuator (56,58) for selectively engaging and disengaging the control lever (34). One regulation factor is provided when the second spring (70) is engaged with the control lever (34) and a second, different regulation factor is provided when the second spring (70) is disengaged from the control lever (34), with engine governing being provided solely by the first spring (28).

In a governor (11) for providing at least two different regulation factors for an internal combustion engine (10) wherein regulation factor is defined as the percent difference between no-load speed and loaded speed for the same throttle setting, the engine (10) including a fuel injection system (12
In a governor (11) for providing at least two different regulation factors for an internal combustion engine (10) wherein regulation factor is defined as the percent difference between no-load speed and loaded speed for the same throttle setting, the engine (10) including a fuel injection system (12) and a throttle linkage (36), the governor (11) being of the type having a rotatable flyweight assembly (18, 20, 22) adapted to be driven by the engine (10), a first spring (28) disposed to be compressed by the flyweight assembly (18, 20, 22) proportional to engine speed, and a control lever (34) associated with the first spring (28) for opposing the force of the flyweight assembly (18, 20, 22), said control lever (34) compressing the first spring (28) proportional to a desired engine speed, the flyweight assembly (18, 20, 22) and the first spring (28) being adapted to be connected to the fuel injection system (12), the improvement comprising: a second compressible spring (70); and actuator means (56, 58, 60, 62, 64, 66, 68) for selectively engaging and disengaging said second spring (70) from said control lever (34) to provide a first regulation factor based on the combined chosen spring rates of said first and second springs (28, 70) when said second spring (70) is engaged with said control lever (34) and a second different regulation factor based on the chosen spring rate of said first spring (28) alone when said second spring (70) is completely disengaged from said control lever (34).
