Abstract: A device for locking the throttle linkage of a vehicle comprises a bracket having a pair of aligned openings through which a rod of the linkage can pass. A lever pivotally mounted on the bracket has a free end for engaging the rod between the pair of openings so as to clamp the rod at that point and prevent actuation movement.

The valve is then released to unclamp the linkage and allow normal driving movement of the linkage during operation of the vehicle.

Abstract: A mechanical engine governor includes a gear driven input shaft and an output shaft. A fly-weight assembly is mounted on the input shaft to apply a torque to the output shaft which varies as a function of the rotational speed of the input shaft. An output plate assembly is secured to the output shaft to rotate with the output shaft and is coupled to a fuel metering device such as a fuel injection system for a diesel engine. A stop plate is mounted to rotate about the output shaft, and a spring is mounted between the output plate assembly and the stop plate. At engine speeds below 500 RPM this spring rotates the output plate assembly with respect to the stop plate to provide increased fuel delivery to the engine during engine start up. At speeds greater than 500 RPM the stop plate insures that the governor commands no more than a predetermined maximum continuous fuel flow to the engine.

Abstract: The subject air-fuel ratio control system for an engine includes a fluid-powered broken-link mechanism which is operatively linked between an air-fuel ratio control device and a fuel quantity control member, such as a fuel injection pump rack.

This construction minimizes the duration and quantity of any smoke produced during engine startup, simplifies the cost and construction of the air-fuel ratio control device, and permits relatively easy adjustment of the air-fuel ratio control setting.
