Abstract:
1. A device for sensing the speed of an EMD 567/645/710 two-cycle diesel engine having a crankcase housing a crankshaft, electronic fuel injectors, and an electronic control system for controlling the electronic fuel injectors, the device comprising: a shaft sized for connection to the crankshaft of the engine so that the shaft rotates with the engine; a gear operably secured to the shaft to rotate with the shaft and sized to rotate with the engine in a 1:1 ratio; at least one electronic sensor located adjacent the gear to sense rotation of the gear and connectable to the electronic control system to provide electronic signals to the electronic control system for determining when to inject fuel with the electronic fuel injectors; and an adapter plate for attachment to the engine crankcase and rotatable relative to the gear and the electronic sensor during installation so that the adapter plate can be aligned with the engine crankcase while maintaining positional relationship between the gear and the sensor during installation.
