Foton Cummins ISF series is one of the most widely applied replacement powertrains for light duty commercial vehicles. Professional repair workshops and wholesale distributors often need to differentiate ISF2.8 Euro3, ISF3.8 Euro3 and ISF3.8 Euro4 to meet diverse project demands.

These three engines are designed for distinct load capacities and regional exhaust compliance standards. We have sorted out all their key parameters and applicable scenarios to support your efficient model screening during procurement.

It is a 2.8L inline 4 turbo intercooled diesel engine. Without complicated SCR or DPF after treatment parts, its whole structure is simple, fewer vulnerable components and low daily maintenance cost.

• Power: 120 143 HP
• Peak torque: 360 420 N·m
• Key strengths: Light weight, low fuel consumption, compact installation size
• Best applications: Small light trucks, city delivery vans, mini logistics vehicles, light load equipment in Euro3 compliant regions.

Pick ISF2.8 Euro3 when your projects focus on light payload urban short haul transport. It is cost effective for light duty overhaul.

ISF3.8 Euro3 shares the same Euro 3 emission standard with ISF2.8 Euro3, but steps up to 3.76L displacement.

Also built without SCR / DPF exhaust accessories, it keeps the advantage of easy repair and affordable spare part cost.

• Power: 141 154 HP
• Peak torque: 440 500 N·m
• Key strengths: Strong low speed torque, great climbing and loading performance, robust for heavy load conditions
• Best applications: Heavier payload light trucks, small construction machinery, older fleet rebuilding for markets with loose emission rules.

Choose ISF3.8 Euro3 if customers need to carry heavier cargo, where ISF2.8 power is not enough.

ISF3.8 Euro4 uses the identical 3.76L engine block as ISF3.8 Euro3. The main upgrade lies in exhaust emission system.

It adds EGR + DOC after treatment system to meet Euro4 emission regulations. Power output stays close to Euro3 version, while fuel combustion is optimized for less pollution and lower noise.

• Power:141 154 HP
• Peak torque:450 500 N·m
• Key strengths: Compatible with medium emission markets, good balance among power, fuel economy and environmental requirement
• Best applications: Mid generation logistics trucks, commercial vehicles for countries requiring Euro4 compliance.

Important note: ISF3.8 Euro4 cannot simply swap directly with Euro3 unit. ECU and exhaust piping need matching modification.

1. ISF2.8 Euro3: Light load city delivery, small vans, focus on fuel saving and light weight.
2. ISF3.8 Euro3: Heavy load light trucks, old fleet repair, markets without strict emission inspection.
3. ISF3.8 Euro4: Same heavy load demand, while local law requires Euro4 emission standard.

Always double check original vehicle displacement, ECU type and local emission rules before ordering to avoid fitting mistakes.
