Cummins ISL9 achieves new 536HP rating for defence applications

Posted 12 September 2017 · Add Comment

Cummins has announced that its ISL9 diesel engine is now available up to 536 hp for fast response defence applications

Displayed on Cummins stand at the DSEI show, the ISL9 is already proven in a wide variety of equipment such as armoured vehicles, military trucks and infantry fighting vehicles manufactured by OEMs worldwide. 

“Cummins invests heavily in state of the art engineering test cells which simulate the harsh conditions the engine is exposed to in theatre. Balancing key technologies such as combustion, turbocharging, fuel systems and electronic calibrations allows us to develop the best solution for our customers. This has enabled us to develop the ISL9 engine to a new peak power output of 536hp for military use,” said Nigel Chisman, Defence Marketing Manager.

Cummins ISL9 is a light weight, compact and fuel efficient 8.9 litre engine. It offers distinct advantages to global vehicle manufacturers, with a simplified engine architecture that reduces complexity for ease of installation. For operators it provides high performance with low operating costs and excellent reliability with less parts that could fail.

The ISL9 has developed a strong reputation in automotive, construction and mining use. Cummins has drawn on the knowledge and experience gained from these markets to fully optimize the 9 litre engine, increasing power by 34%.  Torque capability is also increased up to 1,900 Nm.  The optimization of key performance parts and the integration of Cummins HE500 Variable Geometry Turbocharger (VGT) has been key in achieving this improvement.

The VGT has a unique patented one-piece sliding-nozzle design which precisely adjusts the airflow delivered to the engine.  It combines the benefits of a small and a large turbocharger in a single unit.  The sliding nozzle varies the exhaust gas flow into the turbine wheel to provide rapid boost at low engine rpm and then maintain high boost at higher rpm.

“With the new 536hp rating Cummins offers improved engine response time for demanding gradients and tough terrain in challenging climates.  The higher power capability allows vehicles to carry a heavier load; more people, more equipment and more armoury on the vehicle. All without experiencing a reduction in power and speed,” added Chisman.

Wellingborough based Cummins UK supports Cummins engines and generators in operation through aftermarket parts and service support.
