Cummins QSF 2.8 Debuts at Asian Engineering Machinery Exhibition

QSF 2.8 is Cummins's smallest industrial fully-electrically controlled, high-pressure common-rail diesel engine launched this year. It was first presented at the INTERMAT Construction Machinery Exhibition in Paris in April. It is the industry's first choice with a short and small size. Its power is 46-74 hp (35-54 kW). ), to meet the European and American Stage IIIA/Stage IIIB (Tier 4 Final) emission standards, the volume and weight of the engine is equivalent to a smaller displacement, power is not inferior to a larger displacement engine, is a small excavator , 2.5-3.5 tons of forklifts, small compactors and other compact construction machinery and equipment, a great choice of power.

QSF 2.8 integrates the technical advantages of Cummins road and non-road classic models, developed jointly by the technical teams of Europe, China and the United States. It is a global engineering equipment power product. As an intelligent electronically controlled engine, the QSF2.8's electronically controlled system can fully monitor engine parameters and optimize engine performance during the operation of engineering equipment. Through precise control of multiple injection timings and injection volumes of high pressure common rail fuel system (HPCR), combustion is more complete and economical. The high-strength cast iron cylinder body adopts etching design, which effectively reduces the torsional vibration and has high resistance to high pressure. The QSF2.8 uses an efficient rear gearbox drive train to provide better mounting stiffness and reduce noise. The use of high-quality composite materials for valve body covers and other components, lighter weight. The QSF2.8's small, lightweight body allows easy installation and superior dynamics and durability. 2.8 litre naturally aspirated engine, which saves installation space and can easily replace the smaller displacement 2.2-liter engine; its turbocharged engine, compact structure, good fuel economy, greater torque output, and 3.4-liter engine It is beautiful. With the addition of an easy-to-use post-processing device, QSF2.8 can meet the Stage IIIB and Tier 4 Final emission standards.

The basic platform of the QSF2.8 is the same as that of the ISF vehicle diesel engine. It is optimized based on the application characteristics of construction machinery and the needs of the host plant. Since the launch of the ISF series in 2009, more than 100,000 units have been launched in the global market.
