Clean Diesel Technologies in Fuel Borne Catalyst Agreement with Fleetguard

2 September 2005

Clean Diesel Technologies (CDT) has signed a blending and distribution agreement with Fleetguard, Inc., a business unit of Cummins Inc. (CMI), for the sale of Platinum Plus Fuel-Borne Catalyst (FBC) in North America and international markets.

Under the terms of the agreement, Fleetguard will purchase Platinum Plus FBC concentrate from Clean Diesel for blending into finished products for sale to distributors and end users in the on-highway, off-road, marine and power generation markets.

Platinum Plus is a bimetallic platinum/cerium kerosene-based fuel additive used at 4–8 ppm metal in fuel that:

  • Improves fuel economy between 3%–8%

  • Reduces PM emissions by 10–20% (30%–50% when combined with an oxidizer, 95% when combined with filter)

  • Reduces HC and CO emissions by 10%–30% (50% when combined with an oxidizer)

  • Lowers filter regeneration temperature to 300º–350° C.

Presently, there are three options for adding the fuel catalyst: the operator can add it manually to a fuel tank; a fueling station can use a dosing system to add the FBC as the fuel is pumped; or the fuel supplier can pre-mix the additive into the supply delivered to fueling stations.

Clean Diesel and Fleetguard are also cooperating on a fourth option: a new on-board delivery system developed by Fleetguard that incorporates reservoir of FBC into the engine’s fuel filter.

This system will release the FBC into the fuel as it is pumped through the fuel filter on its way to the engine. The dosing system will require no action by the vehicle operator other than having the filter replaced during scheduled maintenance.

Initially targeted at the retrofit market, Clean Diesel is also conducting programs using Platinum Plus FBC in advanced engines with exhaust gas recirculation (EGR) and soot filters to achieve the EPA 2007 emissions standards. The company anticipates that the FBC will allow lower platinum loadings on after-treatment devices, reduce fuel economy penalties of new low-emissions engines, and improve low-temperature regeneration of soot filters in difficult medium-duty urban drive conditions.

Comments

Does something downstream capture the platinum and cerium from the exhaust? Or does it just go into the air?

Both plantinum and cerium will be present in the exhaust. As an aside, studies have show an increase in platinum group element concentrations in ambient air and dust since the introduction of catalytic converters.

According to CARB, catalytic converters contribute more platinum into the environment than other industrial sources.

Long-term effects of both nanoparticulate cerium oxide and platium are poorly understood at this point.
