The ISF 3.8 is perfect for light commercial vehicles because of its outstanding performance, light weight, low operating costs, and the dependability and durability expected from Cummins. For installations over 3.5 tonnes GVW that are space-constrained and weight-sensitive, the ISF 3.8 is the best option because it is the lightest and most powerful engine in its class.
Easy access and one-way service are made possible by modular engine design, which lowers overall operating costs. Higher operating temperatures are made possible by the high temperature capability at the top of the tank, which lowers the size and cost of the cooling unit needed for the car.
A high-speed network is utilized in conjunction with the Electronic Control Module (ECM), which has a standard data link that receives input from all drivetrain components. An ideal balance between load elements, fuel efficiency, and emissions control is maintained by the ECM’s high processing power.
The engine’s HPCR (High Pressure Common Rail) system offers exact control over the combustion process and can run at very high pressures. It can also produce injection pressures that offer better and quicker power delivery, reduced noise, and fuel efficiency.
Cummins Turbo Technologies’ Wastegated Turbocharger offers outstanding performance throughout the whole power range and enhanced responsiveness by producing more torque at low revs. Cummins Filtration’s state-of-the-art oil and fuel filtration systems, which offer exceptional engine protection, are part of the line.
Cummins ISF 3.8 complies with Euro 4. Selective Catalytic Reduction (SCR) technology is used to achieve emission compliance. SCR is the most cost-effective way to lower NOx emissions in trucks and light buses. It is also the best technology for maximizing fuel efficiency, which enables the engine to run cleaner. Cummins Emissions Solutions created the fully integrated internal design of ISF’s SCR system. As a matter of fact, Cummins is the only manufacturer of diesel engines with patented integrated core technologies, ranging from exhaust aftertreatment to air intake.
