Overview
The Cummins ISDe185 is a 4.5 / 6.7 L 4 / 6-cylinder Cummins diesel engine supplied in 4 factory ratings from 182 hp (136 kW) to 182 hp (136 kW). Every rating listed on this page is a complete engine for on-highway duty, not a generator set, and each unit ships with its serial number recorded against the specification sheet that applies to it.
Ratings in this family differ in rated speed, peak torque and emissions tier rather than in displacement or cylinder count, so the choice between them is a duty-matching question. The specifications panel and the per-rating entries on this page are generated from the same source data, so a rating quoted here can be matched directly against a delivery document.
Specifications
The specifications panel lists the family-level values that are common to every ISDe185 rating, including the 4.5 / 6.7 L displacement and the inline 4 / 6-cylinder layout. Ratings that share displacement and cylinder count but differ in output are listed individually in the model selection section.
Model Selection: ISDe185 Ratings
Each entry in this section is one rating of the Cummins ISDe185. The rated power is the output at the stated speed; the peak torque figure is the value the rating develops at the lower speed shown, which is what normally decides whether a rating suits a given machine. Each rating carries a stable anchor, so a single rating can be linked or quoted directly.
ISDe185 30
ISDe185 30 — rated 136 kW (182 hp) at 2500 rpm; peak torque 700 N·m at 1400 rpm; emissions EuroIII.
ISDe185 40
ISDe185 40 — rated 136 kW (182 hp) at 2500 rpm; peak torque 700 N·m at 1400 rpm; emissions EuroIV.
ISDe185 31
ISDe185 31 — rated 136 kW (182 hp) at 2500 rpm; peak torque 650 N·m at 1400 rpm; emissions EuroIII.
ISDe185 41
ISDe185 41 — rated 136 kW (182 hp) at 2300 rpm; peak torque 700 N·m at 1400 rpm; emissions EuroIV.
Applications
ISDe185 engines in this family are normally specified for on-highway work.
On-highway: ratings are selected against the gross vehicle weight, the intended road speed and the emissions standard that applies in the destination market.
Emissions: the ratings listed here carry EuroIII or EuroIV. Where a market imposes a different standard, confirm the tier before ordering, because the same model number can be built to more than one tier.
Verification, Documentation and Ordering
Each engine is offered with nameplate verification + load-test record per serial number. That means the model and rating printed on the engine nameplate can be checked against the record issued for that serial number before shipment, which is the point most buyers of re-rated or re-exported engines want covered.
To receive a quotation, send the exact rating from the matrix above (for example ISDe185 41), the machine or application it will drive, the quantity, and the destination port. If the rating you need is not listed, send the model and the required output and we will confirm whether it belongs to this family or to a neighbouring one.
Buyer tip: Send your ISDe185 specification, quantity and destination port for a verified quotation and lead time.
Frequently Asked Questions
What displacement and cylinder count does the ISDe185 use?
Every rating in this family shares the same 4.5 / 6.7 L displacement and inline 4 / 6-cylinder, 4-cycle configuration. Ratings differ in output, rated speed and emissions tier rather than in the base engine.
What is the difference between ISDe185 31 and ISDe185 41?
ISDe185 31 is rated 136 kW (182 hp) at 2500 rpm with peak torque of 650 N·m, while ISDe185 41 is rated 136 kW (182 hp) at 2300 rpm with 700 N·m. They use the same base engine; the higher rating is the one to specify when the driven load needs the extra torque at the lower speed.
Which emissions tiers are available for the ISDe185?
The ratings on this page are listed as EuroIII and EuroIV. Emissions tier is part of the rating definition, so state the tier your market requires when you request a quotation.
How is a ISDe185 rating ordered?
Send the exact rating shown in the model selection table, the application it will drive, the quantity and the destination port. The engine is then quoted against that rating and confirmed against its nameplate and load-test record.
