Key Benefits

- Peak torque of 1966 N.m @ 1200 rpm holds the load without downshifting or derating.
- Turbocharged & Charge Air Cooled induction with water cooling keeps charge temperature under control in continuous duty.

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 ISZ 317KW 425HP Vehicle Diesel Engine variant from a serial number takes experience; MEP Power checks the configuration before quoting.

How It Compares
| Compared with | What to consider |
|---|---|
| A rebuilt or used engine of the same rating | A rebuilt unit may show the same 317 kW (425 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same Cummins 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. |
