Cordierite Diesel Particulate Filter on GM 7.8 Isuzu. Unlike a catalytic converter which is a flow-through device, a DPF retains bigger exhaust gas particles by forcing the gas to flow through the filter material before exiting; [2] [29] however, the DPF does not retain small particles. Maintenance-free DPFs oxidise or burn larger particles ...
Early in the 1950s scientists discovered that vehicle emissions were a significant factor that had been causing the air quality to deteriorate. [7] This led to the introduction of vehicle emissions standards in California in 1966, furthermore due to the seriousness of the problem, in 1970 the Clean Air Act was introduced in order to regulate these standards all over the United States.

Catalytic converters remove only 20–40% of PM so particulates are cleaned up by a soot trap or diesel particulate filter (DPF). In the U.S., all on-road light, medium, and heavy-duty diesel-powered vehicles built after 1 January 2007, are subject to diesel particulate emission limits, and so are equipped with a 2-way catalytic converter and a ...
On September 26, 2007, Toyota recalled 55,000 sets of heavy-duty rubber floor mats from the Toyota Camry and ES 350 sedans. [34] The recalled mats were of the optional "all-weather" type. NHTSA stated that the recall was due to the risk that unsecured mats could move forward and trap the accelerator pedal. [34]
To achieve this standard, Cummins and other diesel engine manufacturers developed an aftertreatment system that includes the use of a diesel particulate filter (DPF). 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 fuel (ULSD) to prevent damage ...
California vehicles with 2.5, 2.8 and 3.5 liter engines will have a CLCC system. In 1980 model year, vehicles sold in California and 3.8 and 4.3 liter engines sold federally will have CLCC, and finally in the 1981 model year all passenger cars will have the system. California light and medium duty trucks may also use the c-4 system.
2005–2009 Third Generation Toyota Corolla Verso 2.2 D-CAT [5] 2007-2013 Toyota Corolla (E140) 2.2 D-CAT; 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 . Technical specifications: [6]
The Toyota Camry (XV10) is a mid-size car that was produced by Toyota between 1991 and 1996 in Japan and North America, and 1993 and 1997 in Australia. The XV10 series represented the third generation of the Toyota Camry in all markets outside Japan, which followed a different generational lineage. The XV10 Camry range is split into different ...
