Abstract

Diesel engine is one type of engine that is very suitable for use in heavy equipment transportation because it has a large performance value (torque and power). The purpose of this study is to determine the effect of engine speed variations on the performance value of the Liebherr D9512 Engine. Data collection was carried out when the engine was operated using a Power Test Dynamometer 35X05 test tool. The results of the tests carried out showed that variations in engine speed will affect the performance value. At 1100 RPM engine speed the torque value is 2204 N.m on the remanufactured dynotest results and 2211 N.m on the factory dynotest results. At 1500 RPM engine speed the torque value is 3489 N.m and 3496 N.m on the factory dynotest results. At 2000 RPM engine speed the torque value is 2754 N.m and 2883 N.m on the factory dynotest results. On the other hand, variations in engine speed also affect the engine power value. Test data at 1100 RPM engine speed, the power value is 253 KW on the remanufacture dynotest results and 268 KW on the factory dynotest results. At 1500 RPM engine speed, the power value is 520 KW and 523 KW on the factory dynotest results. At 2000 RPM engine speed, the power value of the remanufacture dynotest and factory dynotest is the same, namely 565 KW.
