ISF3.8S4R
Cummins
The Cummins ISF3.8S4R is a premium 3.8-liter diesel engine designed to deliver an exceptional balance of power, fuel economy, and durability. As a core model of the F-series, this compact and lightweight engine is engineered for superior performance in a wide range of applications, building upon the reliability of the platform with enhanced capability.
This engine is an excellent choice for modern lightweight vehicles where power-to-weight ratio and operational efficiency are critical:
Light and Medium-Duty Trucks: Including urban distribution trucks, pickup trucks, and utility vehicles.
Special Purpose Vehicles: Such as crane trucks and other vocational equipment.
Non-Road Machinery: Can be adapted for use in compact construction equipment and generator sets.
The “4R” designation commonly indicates compliance with Euro IV / China National IV emission standards, making it a proven solution for regulated markets.
The ISF3.8S4R incorporates several advanced technologies to meet today's performance and environmental demands:
Advanced Fuel System: Equipped with a High-Pressure Common Rail (HPCR) fuel system. This technology enables higher injection pressure, more precise fuel metering, and optimized combustion, resulting in lower fuel consumption, reduced noise, and improved cold-start performance.
Efficient Turbocharging: Features a wastegate turbocharger designed to provide excellent responsiveness and strong low-end torque across the entire operating range, enhancing drivability under load.
Full Electronic Control: As part of a new generation of fully electronically controlled diesel engines, it allows for precise engine management, seamless integration with vehicle systems, and advanced diagnostics.
Designed for Durability: Utilizes a modular architecture and integrated design with fewer parts compared to previous generations, significantly improving reliability and reducing potential maintenance needs.
