Legislation All diesel powered equipment with power ratings of between 174 and 751 hp supplied in North America had to meet the requirements of Tier 4i (interim) and Stage IIIB emissions regulations. This means, for example, that ® High Capacity Lift Trucks with lifting capacities above 32,000 lbs, including container handlers and ReachStackers, had to be provided with new engines and emissions management technologies. The regulations require diesel engines to reduce Particulate Matter (PM) exhaust emissions by 90% and Oxides of Nitrogen (NOx) exhaust emissions by 45% compared with Tier 3 and Stage IIIA emissions standards. Hyster spent years developing and testing new products that not only complied with the legislation, but provided significant financial savings for the customer through fuel savings of up to 20%. In November 2010, Hyster was the first company in the world to launch a range of high capacity lift trucks equipped with a range of Tier 4i / Stage IIIB compliant diesel engines, featuring an integrated Diesel Particulate Filter exhaust after-treatment and a cooled exhaust gas recirculation (EGR) system so the operator can fill the fuel tank as normal. In addition to Cummins engine technologies which help ensure high power ratings and extensive peak-performance, Hyster® optimized truck functions to provide intelligent engine speed control, including hibernate idle, load sensing hydraulics and demand sensitive cooling systems. This innovative combination means that the High Capacity Internal Combustion range can offer fuel savings of up to 20%. In fact, one terminal has reported a saving of 1.3 gallons per hour compared to a competitor model used in the same operation.
