The operator's interface with the engine control is provided by the Caterpillar Electronic Technician (ET) and by the optional control panel. For information on Cat ET, refer to Systems Operation/Testing and Adjusting, "Electronic Service Tools".
Many of the engine control's parameters can be programmed for the specific site. For information on the programmable parameters, refer to Systems Operation/Testing and Adjusting, "Electronic Control System Parameters".
The starting motor solenoid, the Gas Shutoff Valve (GSOV), and other components are used to control start-up and shutdown. For information on start/stop sequencing, refer to Systems Operation/Testing and Adjusting, "Start/Stop Control".
The ECM provides the timing and the voltage for ignition. For information on ignition control, refer to Systems Operation/Testing and Adjusting, "Ignition System".
Feedback from sensors and adjustment of the air/fuel ratio control or fuel metering valve enable control of the exhaust emissions. The G3516 TA engine uses O2 sensors for Oxygen feedback. For information on air/fuel ratio control, refer to Systems Operation/Testing and Adjusting, "Air/Fuel Ratio Control".
The desired speed is maintained through control of the throttle actuator. For information on governing of the engine, refer to Systems Operation/Testing and Adjusting, "Engine Governing".
Other sensors enable the ECM to monitor the engine operation. For information on engine monitoring and protection, refer to Systems Operation/Testing and Adjusting, "Engine Monitoring System".
