What This Engine Is Built For
Cummins ISLe340-30: a 6-cylinder in-line vehicle diesel engine displacing 8.9 L on a 114 * 144.5 mm bore and stroke, supplied complete by MEP Power. It is rated at 250 kW (340 HP) at 2100 rpm and develops 1425 N.m @ 1100-1400 rpm. The engine is turbocharged & charge air cooled and water cooled, with a Bosch Common rial (CCR)/ECM Governor fuel system. It is built at the Dongfeng Cummins Plant and carries Euro III. Typical duty is trucks, buses, coaches and municipal vehicles; dry weight with flywheel and alternator is 706 Kg and the overall envelope is 1147mm*767mm*1104mm.
Key Benefits
- Delivers 250 kW (340 HP) at 2100 rpm from 8.9 L as a factory-rated assembly.
- Peak torque of 1425 N.m @ 1100-1400 rpm holds the load without downshifting or derating.
- Turbocharged & Charge Air Cooled induction with water cooling keeps charge temperature under control in continuous duty.
- Supplied to Euro III, so the unit can be registered in markets that require it.
- Dry weight 706 Kg and envelope 1147mm*767mm*1104mm are published so the installation can be checked before ordering.
- Rated for continuous running up to 4500 m altitude.
Application Scenarios
- Heavy truck engine assembly replacement
- City bus and coach repower
- Mixer, tipper and refuse body chassis
- Light commercial vehicle conversion
Who It Is For
- Truck and bus fleets doing engine assembly swaps instead of in-frame rebuilds
- Body builders and chassis converters specifying a known driveline
- Workshops supporting Dongfeng and other Cummins-powered vehicles
- Municipal fleets running refuse, mixer and utility bodies
Problems It Solves
- In-frame rebuilds tie up a bay for days and still leave old ancillaries in service.
- Emission compliance has to be matched to the market the vehicle runs in.
- Mixed fleets with several engine families multiply the parts a workshop must carry.
- Identifying the right ISLe340-30 variant from a serial number takes experience; MEP Power checks the configuration before quoting.

- Match the flywheel housing and clutch to the existing gearbox
- Check the emission level required in the registration market before ordering
- Re-use the vehicle's cooling pack only if it meets the engine's heat rejection

How It Compares
| Compared with | What to consider |
|---|---|
| A rebuilt or used engine of the same rating | A rebuilt unit may show the same 250 kW (340 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same ISLe range | Moving up a frame size adds weight, envelope and fuel burn; specify the next size up only if the duty cycle really needs the headroom. |
| A non-Cummins engine of similar output | Parts and service for Cummins families are available in most markets, which matters more over ten years than the purchase price on day one. |
