Cummins ISF engine range for light vehicles

T he ISF 2.8 and 3.8  ℓ , four-cylinder engines are the latest additions to Cummins’ extensive range of dependable engines, and are ideal for use in light commercial vehicles. “Cus- tomers stand to benefit from exceptional performance and low operating costs, with the reliability and durability expected from Cummins,” says sales and business develop- ment manager, Bo Fu, adding that the key environmental benefits of the range include low noise and emissions. The ISF engine family offers exceptional performance, low weight and operating costs, and improved durability. It has been developed specifically for light commercial applications such as trucks, vans, pick-up trucks, and utility vehicles. The high torque and power availability makes them ideal for weight-sensitive and space-constrained installations below 3.5 t GVW (gross vehicle weight). The ISF 2.8 is the lightest and strongest engine in its displacement class. Catering for Euro III and IV emissions levels, it offers advanced thermal engineering, electronic integration, and a high-pressure common rail (HPCR)system.Inaddition,aCumminswaste-

The design of the 2.8 and 3.8 litre engines featuremodular architecture for easy access and single-side servicing, reducing overall operating costs. Ahigh top-tank temperature capability facilitates higher operating tem- peratures, thereby reducing the size and cost ofthecoolingpackagerequiredonthevehicle. The electronic control module (ECM) has an industry-standard datalink that accepts input from all powertrain components, cre- ating a seamless flow of shared information, along with a high-speed network. The high processing capability of the ECM maintains an optimum balance between load elements, fuel efficiency, and emissions control. Fu points out that the engine’s HPCR system can function at an extremely high pressure, and provides precise control of the combustion process. Moreover, it can gener- ate injection pressures that allow for refined and rapid power delivery, lownoise, and fuel- efficient performance.

The rangehas the latest class-leading oil and fuel filtration systems developedbyCummins Filtration for high engine protection. “Cummins is committed to meeting inter- national emissions standards by adopting the right technology for eachmarket’s emissions limits, test cycles and operational factors. No other engine company has all of the critical sub-systems in-house: electronic control, air handling, fuel systems, combustion technol- ogy, filtration and exhaust after-treatment,” Fu assures. q
