We are a global vertically integratedmanufacturer and distributor of emissionscontrol systems and products, with a wellestablished London base. Our turnkeyin-house skills range from applicationsengineering and manufacture to patentedcatalysation techniques. This gives us thefreedom to develop new solutions for specificmarkets, free from the constraints of out-dated technologies.


CClleeaann DDiieesseell TTeecchhnnoollooggiieess is a low emissions specialist providing sustainablesolutions to reduce emissions, increase energy efficiency and lower the carbonintensity of on- and off-road engine applications. Our patented technologiesand products allow manufacturers and operators to comply with increasinglystrict regulatory emissions and air quality standards, while also improving fueleconomy and power. The Company’s solutions, which are in commercial useworldwide, significantly reduce emissions formed by the combustion of fossil-fuels and bio-fuels, including particulate matter, nitrogen oxides (NOx), carbonmonoxide and hydrocarbons. Our solutions also reduce carbon dioxide (CO2)emissions, a key greenhouse gas associated with global climate change.

Our focus is on the Heavy Duty Diesel (HDD)and Light Duty Vehicle (LDV) markets,utilising our proprietary patented MixedPhase Catalyst (MPC®) technology andPlatinum Plus® Fuel Borne Catalyst (FBC).Over 9 million Clean Diesel catalysts havebeen installed while its diesel particulatefilters have been applied in the mostchallenging conditions, e.g. continuous 18-24 hour day, 7 days a week usage inLondon Bus fleet operations.

The London LEZ, which covers most ofGreater London, was introduced in 2008 toensure the most polluting diesel vehiclesbecome cleaner, to improve the health andquality of life for people visiting, working orliving in London. As LEZ now enters its thirdand fourth phases, Transport for London (TfL)estimates that approximately 150,000vehicles, such as larger vans, minibuses,trucks, buses, coaches, emergency andheavy or specialised diesel vehicles will beaffected by the new regulations.

TfL believes that approximately 20,000 ofthese vehicles will require diesel emissionretrofit solutions. To support this demand,Clean Diesel now supplies a new range ofproducts all fully featured to deliver reliableand cost-effective solutions to customers forLondon LEZ Phase 4.

We have an established network of skilledservice providers who are trained installersand also fully committed to recommendingsystems specific for your purpose – you canbe sure the right advice and solution isavailable at a Clean Diesel installer near to you.

Low Emission Zones are being introduced throughout Europe toencourage the use of less-polluting diesel vehicles.

“Based on our experiences with CleanDiesel in 2008 for the first phase ofLondon LEZ and the quality of thoseinstallations, we are happy to be re-engaging for this next phase…” Chris Hayter, Managing Director, HayterTransport

Petrol DieselDiesel with

Clean Diesel Technology





The Technology

The main reason that most diesel engines appear to produce more exhaustsmoke than comparable petrol engines is because they produce a higher levelof soot particles in the exhaust gases, known as Particulate Matter. The broadobjective of the new legislation is to provide cleaner air inside the Londonconurbation improving human health.

Clean Diesel is an accredited supplier of low emission control solutions.However unlike most competing suppliers, Clean Diesel takes care to alsomeet the primary operational need of all operators – reliability and durability onthe road.

The diagram below provides a comparison of the primary emissions (CarbonDioxide, Nitrogen Oxides and Particulates) produced in the combustion of bothpetrol and diesel fuels and shows the dramatic improvements achievable withClean Diesel’s Technology.

MPC TechnologyCatalytic Solutions MPC® family of ceramicoxide catalytic substrate coatings, and theprocess by which they are applied, are theresult of the development and application ofadvanced material science by our dedicatedproduct development team. The coatingscontain patented mixed-metal oxidesproduced from combinations of low-costmaterial that form active and stable ceramicoxides when fired at high temperatures. Incertain applications, the coatings use smallamounts of platinum group metals togetherwith inexpensive transition metals andlanthanides. When compounded in ourcoatings, their atomic structure uniquelyenables the reactions necessary for high-performance catalytic converters. • Provides flexibility in tailoring performance

characteristics for specific customer requirements

• No ‘sintering’ and loss of surface area that occurs at high temperature

• Catalytic coatings capable of significantly better catalytic performance than previously available

• High levels of performance over time using substantially lower platinum group metals than products previously available

• Proven durability

Platinum PlusPlatinum Plus is a major step forward in FuelBorne Catalyst (FBC) technology, combiningmany of the advantages of previous FBCswith unique benefits of its own. Consisting ofPlatinum and Cerium metallic compoundsformulated as a stable fuel soluble liquid, thetechnology works by introducing very lowlevels of Platinum and Cerium catalyst intothe combustion chambers via the fuel. The catalysts are deposited on the metalsurfaces of the combustion chambersthroughout the exhaust system as activemetals in the soot particles are trapped in theDPF. This results in a significant reduction inDPF regeneration temperature.• Reduces hazardous fumes – higher

particulate reductions• Up to 90% reduction in other gaseous

emissions, HC, NOx, CO and PAH – no additional catalyst hardware needed

• Unlike many alternative regeneration systems based on catalytic hardware. Platinum Plus does not produce unwanted and potentially harmful NO2

emissions during operation

“We’ve also observed the additional benefits of extending the longevity of particulatefiltration components and offering a significant maintenance and running costreduction” Ian Foster, Engineering Director, Metroline Travel Ltd

• Lowest metal content – low ash build-up in the DPF results in longer service intervals

• Improves fuel economy• Includes a diesel detergent – keeps the

engine’s fuel injection system clean, thereby eliminating one of the common causes of DPF failure

Platinum Plus has multiple mechanismsworking simultaneously to provide maximumperformance and long-term durability.

To make this advanced technologycommercially available, Clean Diesel hasdeveloped the new ‘Purifier™ e4’ family offilter systems capable of reducing particulateemissions by up to 98%. In these days ofsoaring fuel costs, this new family is alsorecognised for being able to deliver improvedfuel economy, while still meeting thestringent Low Emission Zone regulations
