Smoke traps based on a four monolithic ceramic filter system (Corning type EX-47) were fitted to the diesel buses in Athens. First results showed that the traps could collect 92% of smoke particles in the exhaust gases. Forced regeneration by exhaust gas throttling was initially tested while the vehicles were stationary in the depot. This was found to be both costly and unsatisfactory because of engine vibration, oil leakage and damage to close-parked vehicles due to high exhaust gas temperatures. The trap design was therefore modified to enable regeneration to take place while the vehicle was in use, without requiring the intervention of the driver. It is proposed to investigate the reliability and cost-effectiveness by installing smoke traps on 250 buses of the Athens fleet.
