   Here is the list of modern emission control technologies applied in Bearford™ diesel generators.

  1. These technologies are used in Bearford™ diesel generators for diesel engines modifications to achieve new EPA tier 3 and tier 4 emission levels. They are very similar to those used on the diesel engines of modern trucks and buses:

  2. Electronic engine microprocessor based control with electronic sensors with possibility to control and adjust injection timing, fuel quantity, turbocharger boost pressure and full electronic fuel injection system, turbochargers with intercoolers.

  3. Exhaust gas recirculation ( EGR ) system – recycling a portion of the inert gases of the exhaust gas stream with incoming engine air. The technique has a dramatic effect on NOx: EGR rates as low as 10% can reduce NOx by 40% without having a significant effect on PM formation or power output.

  4. The real problem in designing a clean diesel  generator engine using above mentioned engine modification techniques  involves a trade-off between NOx and PM ( particulate matters ) emissions. Because when we change the temperature and the speed of ignition to decrease one of these 2 main pollutants the other upraises. So for further decrease of both particulate matters and NOx the following technologies for EXHAUST GAS AFTER TREATMENT are applied in Bearford™ diesel generators wherever necessary:

  5. Selective Catalytic Reduction (SCR) of NOx using an ammonia compound as reductant. In the SCR process, NOx reacts with the ammonia, which is injected into the exhaust gas stream before a special SCR Catalyst. Three forms of reductants can be used in SCR systems: (1) pure anhydrous ammonia, (2) aqueous ammonia and (3)  urea. The chemical reaction which occurs in an ammonia SCR system is shown by this Equation: 4NO+4NH3+O2=4N2+ 6H2O. Application of SCR is the revolutionary method of decreasing NOx in diesel generators emissions.

  6. Further Particulate Matter (PM) Reduction – While diesel engine design modifications are helping to minimize PM emissions, particulate matter (PM) traps are available for installations operating in some non-attainment areas. Diesel PM traps are designed to physically capture visible smoke and soot from the exhaust stream. They can either be simple mechanical filters requiring frequent replacement, or they can be catalytic filters that provide periodic or continuous oxidation (regeneration) of the trapped particulates. Particulate matter traps, catalytic converters and and smoke filters  are employed on diesel generators exhaust systems to achieve further PM reduction efficiencies of up to 90%.

  7. In the past application of catalytic converters for diesel engines and diesel generators was limited by the high sulfur content in non-road diesel fuel damaging them.

  8. Decreasing sulfur levels by the Non-road Diesel Fuel Rule http://www.epa.gov/nonroad-diesel/index.htm will prevent damage to the emission-control systems of diesel generators and significantly decrease PM emission.  In addition, reducing sulfur levels will provide immediate public health benefits by reducing particulate matter from all non-road diesel engines. This rule will reduce current sulfur levels from about 3,000 parts per million (ppm) to 15 ppm when fully implemented (a reduction of greater than 99 percent).

  9. Non-road Diesel Fuel reduces non-road diesel fuel sulfur levels in two steps. First, starting in 2007, fuel sulfur levels in non-road diesel fuel are limited to a maximum of 500 ppm, the same as for current highway diesel fuel.

  10. Second, starting in 2010, fuel sulfur levels in most non-road diesel fuel will be reduced to 15 ppm. This ultra-low sulfur fuel will create immediate public health benefits and will make it possible for diesel engine manufacturers to use mentioned above advanced emission-control systems that will dramatically reduce both PM and NOx emissions without any limitations.
