Final Report - Summary

The ammonia flow rate control system has been developed and implemented. Both diesel fuel and biodiesel were tested together with premixed ammonia. For a constant engine torque with variable ammonia and diesel fuel energy, the ammonia concentration in the engine exhaust is on the order of 1,000 to 4,500 ppm. If 5 percent of the energy comes from diesel fuel and ammonia is used to control the engine torque, the ammonia exhaust concentration ranges from 12,000 ppm to 4,000 ppm.
