A mobile aggregate plant operated by Cedar Rapids, Iowa-based Wendling Quarries is testing the MTU Series 1600 diesel engine used to power a 600-kW standby/550-kW prime-rated generator set. An operator of about 100 quarries in eastern Iowa and western Illinois, Wendling is using the generator set to power primary and secondary crushers, screen plant, conveyors and loaders.
While the portable test plant has a main crusher powered by its own diesel engine, the MTU generator set is being used to run multiple electric motors up to 60 horsepower. At any one time, the total load on the engine is estimated to be about 375 kW, and it operates about 10 hours a day, five days a week.
The Series 1600 is the manufacturer's smallest engine. Combined with the new generator set, it suits emergency standby or prime-power applications. In addition to the 12-volt engine used in the test, the series includes 10-volt and 6-cylinder inline configurations. The engine is equipped with high-pressure, common-rail fuel injection and a high ratio of displacement to horsepower for fast response to load changes. Those features account for its EPA certification; compliance to ISO 8528-5 testing for transient response at 85% load factor (versus standard testing at 70% load factor); and NFPA 110 one-step rated load acceptance (one-step 100% block load).
