Engines and Pollutants
The diesel engine has a superior reliability of service and efficiency but all diesel engines, new as well as old, emit harmful pollutants because of incomplete combustion.
The diesel exhaust consists of following known pollutants:
Our product range mainly consists of diesel oxidation catalysts (DOCs) and diesel particulate filters (DPFs). CDTi systems are tested and approved by AVL/Motortestcenter Sweden; VERT Switzerland; TÜV Germany; and conform to the German TRGS 554 standards. The product housings are manufactured in stainless steel.
We also offer fuel borne catalysts, diesel fuel additives containing catalyst materials that regenerate diesel particulate filters & reduce emissions.
Diesel oxidation catalysts
Purifier™ DOCs from CDTi effectively reduce the gaseous pollutants carbon monoxide (CO) and hydrocarbons (HC) and are offered in several sizes and models. The latest developed models function better at lower exhaust temperatures and the high reduction of hydrocarbons implies a certain reduction of particles. Purifier™ DOCs can be designed to be a direct fit replacement for the manufacturer's original muffler. They can also be combined or built into our Combifilter® particulate filter.
Diesel particulate filters
Our DPFs remove most of the particulate matter, or PM (the soot), of diesel exhaust, replace the original silencer and are available with both active (external) and passive regeneration (self regeneration).
The well known Unikat® Combifilter® which is electrically regenerated, is available in many designs and models and of different filter materials to suit different operating conditions. The Combifilter® functions independent of exhaust temperature and duty cycles and can be combined with a Purifier™DOC.
Purifier®e4 systems combine modern, durable filter hardware with a choice of catalytic technologies to suit driving styles and duty cycles. This allows operation over a much greater range of conditions compared to traditional filter solutions, especially in low-temperature applications - very typical of London-centric operators.
For vehicles running daily with tough duty cycles and thereby high exhaust temperatures, CDTi offers Purifilter®, Purifilter® EGR and Cattrap® with self regenerating filters. These DPFs are dependent upon exhaust temperatures to function.
Our Platinum Plus® and PatFluid® fuel borne catalyst products improve combustion to reduce emissions and enhance the performance of emission control systems. When used with DPFs they reduce regeneration temperatures, enabling cost-effective filter regenerations in various applications.
CDTi also offers spark arresters fully compliant with EU ATEX standards and certified to EN 1834 for use in high explosive environments.
Better products through combined technology
Technology integration is the key to our ability to meet specified demands on both a custom and a cost-effective basis. CDTi exhaust emission control systems are both effective and flexible. You can buy them as they are, or they can be configured to meet the needs of different applications.
