Overview

Diesel 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:

Gaseous pollutants Solid pollutants
CARBON MONOXIDE (CO) PARTICULATE (PM)
  • Odourless and invisible
  • Causes headache, dizziness, nausea
  • Impairs vision and manual dexterity
  • Inhalation 0.3 vol.% can kill
  • Consists of carbon (C), absorbed hydrocarbons, sulphates etc.
  • Stains on products and places
  • Causes lung diseases
  • Mutagenic and carcinogenic
HYDROCARBONS (HC)  
  • Irritate eyes and throat
  • Cause the familiar diesel smell
  • Mutagenic and carcinogenic
 
NITROGEN OXIDES (NO AND NO2)  
  • Contribute to acid rain
  • Cause lung diseases
  • Nitrogen dioxide (NO2) is particularly poisonous



Product range

The product range mainly consists of catalytic oxidation purifiers (DOC) and particulate filters (DPF). The products are tested and approved by AVL/Motortestcenter, Sweden, ARB, U.S.A., VERT Switzerland, TÜV , Germany and conforms to the German TRGS 554 standards. The product housings are manufactured in stainless steel.

Catalytic oxidation purifiers

The catalytic purifiers 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 also at lower exhaust temperatures and the high reduction of hydrocarbons implies a certain reduction of particles. The purifiers can be designed to be a direct fit replacement for the manufacturer's original muffler. They can also be combined or built into the particulate filter Combifilter.

Particulate filters

The particulate filters remove most of the particles, PM, (the soot) of diesel exhaust, replaces the original silencer and is available with both active (extern) and passive regeneration (self regeneration).

 The Unikat Actifilter DB which regenerates with a diesel burner. The system operates independent of exhaust temperature and duty cycles. Can be combined with a catalytic purifier.

The well known Unikat Combifilter which is electrically regenerated, is available in many designs and models and of different filter materials to suit different operation conditions. The Combifilter functions independent of exhaust temperature and duty cycles. Can be combined with a catalytic purifier.

For vehicles running daily with tough duty cycles and thereby high exhaust temperatures ECS offers Purifilter™ and Cattrap™ with self regenerating filters. These particulate filters are dependent of exhaust temperatures to function.

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. ECS 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.
