GROUNDBREAKING NEWSGoing RetroVolvo Engines Retrofit System forConstruction EquipmentAlthough Tier 4 emissions standards for off-highwayengines are just around the corner, Volvo ConstructionEquipment is looking beyond new equipment to cleanup engines already on jobsites. Volvo has enteredinto a strategic partnership with HUSS LLC, a leadingspecialist in diesel particle filtration and systems forexhaust after-treatment, to provide retrofit systems forVolvo construction equipment that will significantlyreduce exhaust emissions and make the air we breathecleaner.The HUSS retrofit system for Volvo equipment iscapable of collecting up to 99 percent of diesel particulatematter (PM) emissions, substantially exceedingthe CARB requirements. Volvo CE will begin its engineretrofit program immediately, utilizing the HUSS MKexhaust after-treatment system.The HUSS system is verified to meet California’s CARBLevel 3 requirements (minimum 85 percent particulatecollection), and Volvo equipment owners using the systemwill be able to meet the “In-Use Off-Road DieselVehicle Regulation,” New York Local Law 77 and futurepending legislation.With their vast experience in after-treatment technologies,additional emissions reduction systems from Volvoand HUSS are coming — first, a passive system allowinga less expensive solution, but for specific machines andapplications, and second, a passive/active system combiningthe benefits of passive and active systems withbroad applications and no machine downtime.HUSS LLC, Palm Springs, Calif., is a specialist in exhaustafter-treatment for diesel engines and has morethan 20 years of experience in the manufacturing andservicing of diesel particulate filtration systems. Applicationsof the HUSS systems include construction andmining equipment, industrial and refuse trucks, transitand school buses, heavy-duty on-highway vehicles andstationary generator sets.The partnership is based on an agreement betweenVolvo headquarters in Sweden and HUSS headquartersin Switzerland, which will make the HUSS systemsalso available for Volvo Trucks, Mack Trucks, VolvoPenta and Volvo Bus engine retrofit applications on aglobal basis.How the Retrofit System WorksThe retrofit system is equipped with a HUSScontrol unit that constantly monitors filter functionto precisely control diesel PM loading andregeneration. The system is integrated into theexhaust system of the vehicle to collect thediesel particulate matter. Active filter regeneration,through an integrated fuel burner system,typically takes place after approximately eightto 10 operating hours and is completed in fiveto 35 minutes. Engine exhaust backpressure isset to Volvo requirements.In addition to the reduction of 99 percent PM,there is no increase of NO2 or other secondaryemissions in the HUSS system. The MK systemis extremely versatile and is applicable over awide range of machines and machine operatingconditions. The HUSS technology is alsoadaptable to high-horsepower equipment (upto 700 hp) providing reliable double-filter installations.The Good, the Bad and the UglyFMI’s Fourth Quarter Report Predict Negative Nonresidential in 200910 Utility Contractor | January 2009While the early months of 2008 offeredwaves of news focusing on greentechnology and energy independence, it’salready clear that the economy will be onthe minds of Americans for at least thefirst half of 2009.
