Equipment ID
The customer can assign an "Equipment ID" for identification for the engine application.Engine Serial Number
The engine serial number is programmed into the ECM at the factory. The number is stamped on the engine information plate.Timing Control
The "Desired Timing" parameters allow the customer to program the timing of the ignition spark of the electronic system to meet the needs for specific applications and specific installations. The desired timing value can be changed while the engine is running or while the engine is stopped. The value that is entered for the desired timing is the ignition timing when the engine is operating at rated speed and at full load.Note: The actual ignition timing at a given instance may vary from the desired timing value. This variance is due to variations in the engine speed or the detonation.The range for programming the desired timing is 0 degrees to 40 degrees before the top center (TC) position."First Desired Timing"
The "First Desired Timing" is determined with the methane number of the primary fuel that is used. Use the Engine Performance Sheet, "Fuel Usage Guide". The ECM selects the "First Desired Timing" when the timing select switch creates an open circuit for terminal J1-20 at the engine ECM.Note: Determine the desired timing by using the Caterpillar Software, LEKQ6378, "Methane Number Program" with the results that are from the fuel analysis. Use of only the data from the gas analysis can result in incorrect settings."Second Desired Timing"
The "Second Desired Timing" is determined with the methane number of the alternate fuel that is used and the Engine Performance Sheet, "Fuel Usage Guide". The ECM selects the "Second Desired Timing" when the timing select switch creates a short circuit to ground for terminal J1-20 at the engine ECM.If an alternate fuel is not used, enter the same timing value for the "Second Desired Timing" parameter that is entered in the "First Desired Timing" parameter.Global Timing Offset
The feature provides the ability to offset the engine's ignition timing to compensate for timing errors that are due to resistances in the electrical circuitry and the stack up of mechanical tolerances.This parameter provides a manual method that will allow more timing adjustment to be performed after calibration of the speed/timing sensor. Perform a negative adjustment to this parameter to retard the engine timing. Perform a positive adjustment to this parameter to advance the engine timing. Only perform an adjustment to this parameter if engine operating indicators and measured data indicate that an adjustment is required.Air/Fuel Ratio Control
Before the initial start-up, a current gas analysis is required. Periodic gas analyses are also recommended. Use the Caterpillar Software, LEKQ6378, "Methane Number Program" to calculate the parameters for air/fuel ratio control for Caterpillar Gas Engines. The results are programmed into the ECM.Note: It is important to use the Caterpillar Software, LEKQ6378, "Methane Number Program". The improper programming of the air/fuel ratio control can result in damage to the engine.The Caterpillar Software, LEKQ6378, "Methane Number Program" is also contained in Caterpillar Software, LERW4485, "GAS ENGINE RATING PRO - VERSION 3.01". This software also contains information that is related to engine performance.Fuel Quality
This is the fuel's Low Heat Value (LHV). The air/fuel ratio control of the ECM will compensate for some inaccuracy in this setting. The ECM derives a corrected value that is multiplied by the "Fuel Correction Factor". The status of the parameter can be viewed with Cat ET.The "Fuel Quality" parameter can be used to change the air/fuel ratio when the engine is operating in the open loop mode. To richen the air/fuel mixture, reduce the value. The calculation will compensate for the reduced LHV by increasing the fuel flow. To lean the air/fuel mixture, increase the value. The calculation will compensate for the increased LHV by reducing the fuel flow.Gas Specific Gravity
This is the fuel's specific gravity in relation to the specific gravity of air. The ECM does not use this information. The ECM provides the information to the fuel metering valve via the CAN data link. Some fuel metering valves require an input for the "Gas Specific Gravity" to precisely meter the fuel flow.Fuel Specific Heat Ratio
This is a ratio of the fuel's specific heat at a constant pressure and at a constant volume. The ratio is also known as "k". The ratio is related to the expansion of the gas across the fuel metering valve. The ECM does not use this information. The ECM provides the information to the fuel metering valve via the CAN data link. Some fuel metering valves require an input for the "Fuel Specific Heat Ratio" to precisely meter the fuel flow.Emissions Feedback Mode Configuration
The "Emissions Feedback Mode configuration" can be set to "NOx Feedback" or to "Feedback Disabled". This feature allows the feedback mode to be disabled to troubleshoot the engine. For example, the disabling of this feature can help determine whether the air/fuel ratio control is the cause of a problem with instability of the engine.If the signal from the NOX sensor is not available, the engine control system does not have the feedback that is necessary for maintaining the desired exhaust emissions.If there is a problem with the NOX sensor, this parameter can be set to "Feedback Disabled" to allow the engine to run in the open loop mode until a new sensor is obtained.
