Four different diesel particulate filter (DPF) systems for city buses have been studied on an engine bench, and based on the results, their practicalities are discussed. On road data of buses operating in Tokyo were collected, and a city bus driving pattern for engine bench test was prepared. Evaluation tests were carried out on an engine bench using an 11-liters engine, used on city buses. The test engine equipped with a DPF system was operated on cyclic test of the city bus driving pattern for the accumulated loading time of 400 hours. Each of the DPF systems has a wall flow monolith filter. A diesel fuel burner or an electric heater with or without catalyst-coated filter is used for regeneration. It is possible to remove about 90 % of particulates from the exhaust gas by the use of DPF systems for diesel engines. Soluble organic fraction (SOF) is reduced by about 30 %. It is difficult to sufficiently remove SOF. No deterioration in the filtering efficiency of particulate matter has been noted after the bus cycle test of 400 hours.
