The Case SR250 and SV300 skid steers and TR320 and TV380 compact track loaders now feature 90-hp (67-kW), 3.4-liter Case diesel engines with the full high-pressure common rail (HPCR) design typically used in larger construction equipment. To meet Tier 4 Interim emission requirements, Case equipped the models with cooled exhaust gas recirculation (CEGR) technology, including diesel particulate filter and diesel oxidizing catalyst. Case selected CEGR technology as most appropriate for skid steers and compact track loader applications, where the engine typically runs at a high RPM.
Rated operating capacities are 2,500 lb (1135 kg) for the SR250; 3,000 lb (1361 kg) for the SV300; 3,200 lb (1451 kg) in the TR320, and 3,800 lb (1723 kg) for the TV380.
“Case skid steers and compact track loaders have always been known for power and productivity,” said Tim O’Brien, Case brand marketing manager. “Our upgraded Alpha Series models not only deliver best-in-class horsepower and industry-leading bucket breakout force – up to 8,585 pounds – but also more torque when you need it.”
He continued, “A 12-percent higher peak torque rise compared to the previous 3.2-liter engine translates into more power at 1400 rpm, while supporting faster recovery and improved reaction when the engine begins to lug.”
O’Brien noted that CEGR technology for Tier 4 is similar to that used in Tier 3, but now the fuel supply and exhaust gas recirculation process are controlled electronically to achieve greater performance and fuel efficiency, as well as even greater reliability – for example, to help protect the engine from overheating.
