Cummins ISBe takes a further leap forward to meet BS-IV and BS-VI emission norms. With an excellent reputation for performance and fuel economy already established worldwide, these engines have been improved in a number of key areas benefiting the operators of rigid trucks, tractor trailers, tippers and buses with higher performance and lower running costs.

Key design enhancements are incorporated in the latest ISBe engines to provide higher power to weight ratios and improved vehicle productivity. Torque and power are increased substantially, allowing these engines to move up to new application classes traditionally associated with engines of higher displacement. Size constrained installations such as full-size buses are now in reach of the ISBe's capabilities. 

The ISBe is unique to Cummins, with superior design benefits for BS-IV. It provides equipment manufacturers with a much more cost-effective power plant backed by the renowned reliability and durability of Cummins B engine platform. Cummins ISBe – the engine for every job!

Emission Norms

Euro - IV/V/EEV

Emissions Technology
meets Euro 4 requirements with the Cummins Integrated Emission Management (IEM) system using Selective Catalytic Reduction (SCR) & Exhaust Gas Recirculation (EGR) technology.
New Electronic Control Module (ECM)
Maintains an optimum balance between load demands, fuel efficiency and emissions control. It is designed to be isolated from detrimental thermal and vibration loading for extreme reliability and durability.
Common Rail System
Works at higher pressure and provides more precise control of the combustion process. Capable of generating up to 1600 bar injection pressures for refined and rapid power delivery, reduced noise, and improved cold start
Rear Engine Power Take-Off (REPTO)
Suitable for applications such as cement mixers thanks to drive capability of 400Nm
Higher Power
4-cylinder engine increases to 210HP and the 6-cylinder engine moves up to 310HP, giving it the highest power to weight ratio in its class
Higher Torque
increased by 17% for improved responsiveness. 4-cylinder engine moves up to 700Nm and the 6-cylinder engine increases to 1100Nm
Low Operating costs
the optimized engine and after-treatment system provides significant reductions in fuel consumption and extends service intervals
Future Proof Design
minimal changes required to meet Euro 5 emission norms and beyond. The Euro 4 ISBe offers significant increase in power and torque. This is provided without penalty to fuel economy. In fact, fuel consumption will reduce by up to 7% with engine service intervals being extended by 60%.
