ISF3.8s4168
Cummins
The Cummins ISF3.8s4168 is a state-of-the-art 3.8-liter, 4-cylinder diesel engine that delivers an industry-leading balance of robust power, superior fuel economy, and legendary durability. Engineered for demanding commercial and industrial applications, this compact and lightweight engine sets a new standard for performance and total cost of ownership in its class.
The ISF3.8s4168 is the power of choice for a wide range of light to medium-duty equipment, providing the torque and reliability needed for maximum productivity:
Commercial Vehicles: Light and medium-duty trucks, urban delivery vehicles, and pickup trucks.
Buses & Passenger Transport: Light buses and school buses.
Specialized Equipment: Versatile enough for crane trucks, utility vehicles, compact construction machinery, and generator sets.
1. Advanced Fuel & Combustion System
At the heart of the ISF3.8s4168 is a Bosch High-Pressure Common Rail (HPCR) direct injection fuel system. This technology enables ultra-precise fuel metering and multiple injections per cycle, resulting in cleaner, more efficient combustion. Combined with Cummins’ advanced combustion optimization and a 4-valve per cylinder design, it achieves excellent power output while minimizing fuel consumption and noise levels.
2. Robust Turbocharged Performance
The engine features a turbocharger with an intercooler, which forces more air into the cylinders for a significant power boost. This design delivers a powerful peak torque of 600 N·m across a wide rpm range (1300-1700 rpm), providing strong pulling power and excellent drivability, especially under load.
3. Full-Authority Electronic Control
A sophisticated Electronic Control Module (ECM) acts as the engine's brain. It provides real-time, precise management of fuel, air, and emissions systems for optimal performance. The ECM also enables comprehensive self-diagnosis, performance data reporting, and easy integration with modern vehicle electronic systems.
4. Engineered for Durability & Low Maintenance
Built with a reinforced structure, including a one-piece cylinder block and gear train, the ISF3.8s4168 is designed for exceptional longevity. Key features contributing to its low total cost of ownership include a B10 design life of 500,000 km (meaning 90% of engines reach this milestone without major overhaul), an extended oil change interval of up to 20,000 km, and a modular design that reduces parts count by 40% for easier serviceability.
