Test Procedure - Natural Gas Engines
The 4S6553 Engine Evaluation Test Group can be used to make operating adjustments on natural gas engines and to determine the approximate power output of natural gas engines.The manifold pressure gauge and differential pressure gauges can be used to make all the operating adjustments to the fuel system of natural gas engines. The tachometer can be used as a reference when making adjustments, but it is recommended that an accurate digital tachometer be used when taking critical speed readings.The manifold pressure gauge can be used to make an approximate setting when balancing the manifold pressure in the two banks of a V-type engine. One needle can be connected into each bank to read the pressure in both banks. As the accuracy of this gauge is marginal for the final setting, it is recommended that the banks be balanced as closely as possible with the manifold pressure gauge, and then one of the differential pressure gauges be used for the final adjustment. The differential pressure gauges can be used for making all of the carburetor and regulator adjustments. Use of the 3B9389 Fittings at the test ports will speed testing by permitting switching of the gauges between ports without the need to shut off the engine. See the appropriate Operation Guide and Service Manual for test port connections, procedures and proper values.The power developed by a natural gas engine, either naturally aspirated or turbocharged, can be determined from the manifold pressure (boost), temperature of the air-fuel mixture in the manifold, and the BTU content of the fuel. Always measure the manifold pressure under the carburetor butterfly for all horsepower calculations. This power determination is accurate only for an engine in good condition with all adjustments correct. Under laboratory conditions, accuracy as close as 3% is possible. Under field conditions, accuracy may be less.Use the following procedure to check the power output of a natural gas engine.1. Run the engine under load until it is at operating temperature. Make a record of the following information at full load speed. Inlet manifold pressureEngine speedAir inlet temperatureAir inlet restrictionExhaust back pressureFuel delivery pressure2. Refer to the charts on pages 24 through 37 of engine horsepower vs. manifold pressure (under the carburetor butterfly) for the engine being tested to determine the power developed by the engine under standard temperature conditions using 1000 BTU per cu. ft. natural gas for fuel. These charts may be extended slightly if necessary. If a curve is not shown for the engine speed desired, the data can be approximated from the data shown. For example, 900 RPM will be midway between the 800 and 1000 RPM curves.3. The horsepower value obtained in step 2 must be corrected for temperature of the air-fuel mixture in the manifold (if the temperature is other than that listed below) and for the heating value of the fuel used if natural gas is not the fuel. Corrections may be calculated as follows. Temperature CorrectionsThe power outputs
