For the sample case study considered, the fuel penalty associated with CPF usage was reduced with higher PM loadings of the CPF, higher target temperatures at the inlet to the CPF and higher time constant of the low pass filter to the OCC inlet temperature. Also, different sized exhaust systems can be evaluated for active regeneration strategies using the VEASS model and a different sized CPF is simulated for illustration.

Therefore, they need to be installed at a point in the exhaust system where the exhaust gas temperature is normally over this level, and reaches it soon after a cold start, meaning the best location is usually upstream of the silencer. They must be protected from engine vibration so there should always be a bellows between the engine and the catalytic converter.
If the fuel contains more than 50 ppm of sulphur, Blackthorn can supply a special washcoat which can tolerate this, but periodic cleaning will be required. In these situations, we normally design the catalytic converter so that the substrate can be removed easily from the housing. Catalytic converters are completely passive, i. As no commissioning is required, we can supply them to customers anywhere in the World. Blackthorn has been supplying catalytic converters for diesel engines for over 20 years, but we have also kept up with changes in technology and therefore make use of nanotechnology coatings, which provide high levels of efficiency whilst being economical in terms of precious metal content.
After being coated with a catalyst, it is applied to the purification treatment of diesel vehicle exhaust in the catalytic converter, the harmful substances in the exhaust gas emitted by automobiles are catalytically converted and purified to meet the requirements of emission regulations.
