The Cummins ISF2.8 is a 2.8-liter, four-cylinder diesel engine.
It features a compact design that makes it well-suited for light-duty trucks and smaller commercial vehicles. The engine delivers impressive power and torque, with ratings ranging from 110 to 150 horsepower and 295 to 369 lb-ft of torque. This provides ample power for a variety of applications while ensuring excellent fuel efficiency.
One of the key features of the ISF2.8 is its advanced fuel system. It incorporates high-pressure common rail fuel injection technology, which optimizes fuel delivery for improved combustion efficiency and reduced emissions. The engine also features a wastegate turbocharger that enhances performance and responsiveness across the operating range.
In terms of durability, the ISF2.8 is built to withstand the demands of heavy-duty use. It employs a cast-iron cylinder block for increased strength and longevity. The engine also incorporates a robust piston design and a high-strength forged steel crankshaft, ensuring reliable performance even under severe conditions. Additionally, the ISF2.8 utilizes a maintenance-free crankcase breather system, simplifying maintenance requirements and reducing operating costs.
Moving on to the Cummins ISF3.8, it is a slightly larger 3.8-liter, four-cylinder diesel engine. The ISF3.8 offers increased power and torque compared to the ISF2.8, with ratings ranging from 130 to 178 horsepower and 369 to 520 lb-ft of torque. This makes it suitable for a wider range of applications, including medium-duty trucks, buses, and industrial equipment.
Similar to the ISF2.8, the ISF3.8 incorporates advanced fuel system technology for improved efficiency and emissions performance. It features a high-pressure common rail fuel injection system with precise control over fuel delivery, resulting in optimized combustion and reduced fuel consumption. The engine also utilizes a wastegate turbocharger to enhance power delivery and throttle response.
Durability is a key focus of the ISF3.8 as well.
It utilizes a robust cast-iron cylinder block, along with reinforced pistons and a forged steel crankshaft, to ensure reliable operation under demanding conditions. The engine also features a compact and maintenance-free crankcase breather system, simplifying service intervals and minimizing maintenance costs.
Both the ISF2.8 and ISF3.8 engines are designed to meet stringent emissions regulations, such as Euro 6 and EPA Tier 4 Final standards. They incorporate advanced aftertreatment systems, including diesel particulate filters (DPF) and selective catalytic reduction (SCR), to minimize emissions of particulate matter and nitrogen oxides.
