As the DPF does not function with low-sulfur diesel fuel, diesel engines that conform to 2007 EPA emissions standards require ultra-low-sulfur diesel (ULSD) fuel to prevent damage to the DPF. After a brief transition period, ULSD fuel became common at fuel pumps in the United States and Canada.
2006–2009 Second Generation Toyota Avensis 2.2 D4-D [1] [3] 2006–2009 Third Generation Toyota Corolla Verso 2.2 D4-D [5] The AD series engines would get refreshed to meet Euro V emissions with an upgraded fuel injection system, lower compression and addition of a DPF system collectively called by Toyota as Toyota Optimal Drive .
