Black Carbon Concentration from Passenger Diesel Vehicles

摘要

In this research, we explored the effect of modification of diesel electric hybrid vehicle on diesel engine exhaust characteristics when the vehicle was driven on a real road. We performed idle exhaust emission test and actual urban road driving test. We repeated the same driving test for 4 different conditions; A) Hybrid mode : two motors operate at approximately 90% of power and the diesel engine operates at idle, B) Engine mode without Generator : only diesel engine operates to run the original vehicle, C) Engine mode with Generator OFF : only diesel engine operates to run the original vehicle while the generator was installed but was not in operation, D) Engine mode with Generator ON : only diesel engine operates to run the original vehicle, the generator was installed and in operation.
